Fix build, documentation, and tests.
This commit makes it possible to build, document, and test Rocket v0.4. The main changes are: * A `Cargo.lock` was added that includes references to yanked deps. * The `tls` feature isn't tested as `ring` fails to build. * The site guide was moved to `docs/guide`. * The `site/` directory was removed.

END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
{one line to give the program's name and a brief idea of what it does.}

||||

the Free Software Foundation, either version 3 of the License, or
|
||||
(at your option) any later version.

|
||||

||||
You should have received a copy of the GNU General Public License
|
||||
along with this program. If not, see <http://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program does terminal interaction, make it output a short
|
||||
notice like this when it starts in an interactive mode:
|
||||
|
||||
{project} Copyright (C) {year} {fullname}
|
||||
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, your program's commands
|
||||
might be different; for a GUI interface, you would use an "about box".
|
||||
|
||||
You should also get your employer (if you work as a programmer) or school,
|
||||
if any, to sign a "copyright disclaimer" for the program, if necessary.

||||

The GNU General Public License does not permit incorporating your program

|

may consider it more useful to permit linking proprietary applications with
|
||||
the library. If this is what you want to do, use the GNU Lesser General
|
||||
Public License instead of this License. But first, please read

|
||||
* `guide/*.md` - Guide pages linked to from `guide.md`.
|
||||
|
||||
[Rocket Programming Guide]: https://rocket.rs/v0.4/guide/
|
||||
|
||||
### Guide Links
|
||||
|
||||
Cross-linking guide pages is accomplished via relative links. Outside of the
|
||||
index, this is: `../{page}#anchor`. For instance, to link to the **Quickstart >
|
||||
Running Examples** page, use `../quickstart#running-examples`.
|
||||
|
||||
### Aliases
|
||||
|
||||
Aliases are shorthand URLs that start with `@` (e.g, `@api`). They are used
|
||||
throughout the guide to simplify versioning URLs to Rocket's source code and the
|
||||
Rocket API. They are replaced at build time with a URL prefix. At present, the
|
||||
following aliases are available, where `${version}` is Rocket's version string
|
||||
at the time of compilation:
|
||||
|
||||
* `@example`: https://github.com/SergioBenitez/Rocket/tree/${version}/examples
|
||||
* `@github`: https://github.com/SergioBenitez/Rocket/tree/${version}
|
||||
* `@api`: https://api.rocket.rs/${version}
|
||||
|
||||
For example, to link to `Rocket::launch()`, you might write:
|
||||
|
||||
```md
|
||||
Launch an instance of your application using the [`launch()`] method.
|
||||
|
||||
[`launch()`]: @api/rocket/struct.Rocket.html#method.launch
|
||||
```

Like other important features, JSON works through Rocket’s `FromData` trait,

Rocket’s approach to deriving types from body data. It works like this:

specify a `data` route parameter of any type that implements `FromData`. A

value of that type will then be created automatically from the incoming
|
||||
request body. Best of all, you can implement `FromData` for your types!

<!-- we should be able to generate the title and subheading -->
|
||||
|
||||
Today marks the first major release since Rocket's debut a little over a month
|
||||
ago. Rocket v0.2 packs a ton of new features, fixes, and general improvements.
|
||||
Much of the development in v0.2 was led by the community, either through reports
|
||||
via the [GitHub issue tracker](https://github.com/SergioBenitez/Rocket/issues)
|
||||
or via direct contributions. In fact, there have been **20 unique contributors**
|
||||
to Rocket's codebase since Rocket's initial introduction! Community feedback has
|
||||
been incredible. As a special thank you, we include the names of these
|
||||
contributors at the end of this article.
|
||||
|
||||
## About Rocket
|
||||
|
||||
Rocket is a web framework for Rust with a focus on ease of use, expressibility,
|
||||
and speed. Rocket makes it simple to write fast web applications without
|
||||
sacrificing flexibility or type safety. All with minimal code.
|
||||
|
||||
> Rocket's so simple, you feel like you're doing something wrong. It's like if
|
||||
> you're making fire with rocks and suddenly someone gives you a lighter. Even
|
||||
> though you know the lighter makes fire, and does it even faster and better and
|
||||
> with a simple flick, the rock's still in your brain.
|
||||

|
||||
|
||||
## New Features
|
||||
|
||||
Rocket v0.2 includes several new features that make developing Rocket
|
||||
applications simpler, faster, and safer than ever before.
|
||||
|
||||
### Managed State
|
||||
|
||||
Undoubtedly, the star feature of this release is **managed state**. Managed
|
||||
state allows you to pass state to Rocket prior to launching your application and
|
||||
later retrieve that state from any request handler by simply including the
|
||||
state's type in the function signature. It works in two easy steps:
|
||||
|
||||
1. Call `manage` on the `Rocket` instance corresponding to your application
|
||||
with the initial value of the state.
|
||||
2. Add a `State<T>` type to any request handler, where `T` is the type of the
|
||||
value passed into `manage`.
|
||||
|
||||
Rocket takes care of the rest! `State` works through Rocket's [request
|
||||
guards](../../guide/requests/#request-guards). You can call `manage` any number
|
||||
of times, as long as each call corresponds to a value of a different type.
|
||||
|
||||
As a simple example, consider the following "hit counter" example application:
|
||||
|
||||
```rust
|
||||
struct HitCount(AtomicUsize);
|
||||
|
||||
#[get("/")]
|
||||
fn index(hit_count: State<HitCount>) -> &'static str {
|
||||
hit_count.0.fetch_add(1, Ordering::Relaxed);
|
||||
"Your visit has been recorded!"
|
||||
}
|
||||
|
||||
#[get("/count")]
|
||||
fn count(hit_count: State<HitCount>) -> String {
|
||||
hit_count.0.load(Ordering::Relaxed).to_string()
|
||||
}
|
||||
|
||||
fn main() {
|
||||
rocket::ignite()
|
||||
.mount("/", routes![index, count])
|
||||
.manage(HitCount(AtomicUsize::new(0)))
|
||||
.launch()
|
||||
}
|
||||
```
|
||||
|
||||
Visiting `/` will record a visit by incrementing the hit count by 1. Visiting
|
||||
the `/count` path will display the current hit count.
|
||||
|
||||
One concern when using _managed state_ is that you might forget to call `manage`
|
||||
with some state's value before launching your application. Not to worry: Rocket
|
||||
has your back! Let's imagine for a second that we forgot to add the call to
|
||||
`manage` on line 17 in the example above. Here's what the compiler would emit
|
||||
when we compile our buggy application:
|
||||
|
||||
```rust
|
||||
warning: HitCount is not currently being managed by Rocket
|
||||
--> src/main.rs:4:21
|
||||
|
|
||||
4 | fn index(hit_count: State<HitCount>) -> &'static str {
|
||||
| ^^^^^^^^^^^^^^^
|
||||
|
|
||||
= note: this State request guard will always fail
|
||||
help: maybe add a call to 'manage' here?
|
||||
--> src/main.rs:15:5
|
||||
|
|
||||
15| rocket::ignite()
|
||||
| ^^^^^^^^^^^^^^^^
|
||||
|
||||
warning: HitCount is not currently being managed by Rocket
|
||||
--> src/main.rs:10:21
|
||||
|
|
||||
10 | fn count(hit_count: State<HitCount>) -> String {
|
||||
| ^^^^^^^^^^^^^^^
|
||||
|
|
||||
= note: this State request guard will always fail
|
||||
help: maybe add a call to 'manage' here?
|
||||
--> src/main.rs:15:5
|
||||
|
|
||||
15 | rocket::ignite()
|
||||
| ^^^^^^^^^^^^^^^^
|
||||
```
|
||||
|
||||
You can read more about managed state in the [guide](../../guide/state/), the
|
||||
API docs for [manage](@api/rocket/struct.Rocket.html#method.manage), and the API
|
||||
docs for [State](@api/rocket/struct.State.html).
|
||||
|
||||
### Unmounted Routes Lint
|
||||
|
||||
A common mistake that new Rocketeers make is forgetting to
|
||||
[mount](../../guide/overview/#mounting) declared routes. In Rocket v0.2, Rocket
|
||||
adds a _lint_ that results in a compile-time warning for unmounted routes. As a
|
||||
simple illustration, consider the canonical "Hello, world!" Rocket application
|
||||
below, and note that we've forgotten to mount the `hello` route:
|
||||
|
||||
```rust
|
||||
#[get("/")]
|
||||
fn hello() -> &'static str {
|
||||
"Hello, world!"
|
||||
}
|
||||
|
||||
fn main() {
|
||||
rocket::ignite().launch();
|
||||
}
|
||||
```
|
||||
|
||||
When this program is compiled, the compiler emits the following warning:
|
||||
|
||||
```rust
|
||||
warning: the 'hello' route is not mounted
|
||||
--> src/main.rs:2:1
|
||||
|
|
||||
2 | fn hello() -> &'static str {
|
||||
| _^ starting here...
|
||||
3 | | "Hello, world!"
|
||||
4 | | }
|
||||
| |_^ ...ending here
|
||||
|
|
||||
= note: Rocket will not dispatch requests to unmounted routes.
|
||||
help: maybe add a call to 'mount' here?
|
||||
--> src/main.rs:7:5
|
||||
|
|
||||
7 | rocket::ignite().launch();
|
||||
| ^^^^^^^^^^^^^^^^
|
||||
```
|
||||
|
||||
The lint can be disabled selectively per route by adding an
|
||||
`#[allow(unmounted_route)]` annotation to a given route declaration. It can also
|
||||
be disabled globally by adding `#![allow(unmounted_route)]`. You can read more
|
||||
about this lint in the [codegen documentation](@api/rocket_codegen/index.html).
|
||||
|
||||
### Configuration via Environment Variables
|
||||
|
||||
A new feature that makes deploying Rocket apps to the cloud a little easier is
|
||||
configuration via environment variables. Simply put, any configuration parameter
|
||||
can be set via an environment variable of the form `ROCKET_{PARAM}`, where
|
||||
`{PARAM}` is the name of the configuration parameter. For example, to set the
|
||||
`port` Rocket listens on, simply set the `ROCKET_PORT` environment variable:
|
||||
|
||||
```sh
|
||||
ROCKET_PORT=3000 cargo run --release
|
||||
```
|
||||
|
||||
Configuration parameters set via environment variables take precedence over
|
||||
parameters set via the `Rocket.toml` configuration file. Note that _any_
|
||||
parameter can be set via an environment variable, include _extras_. For more
|
||||
about configuration in Rocket, see the [configuration section of the
|
||||
guide](../../guide/overview#configuration).
|
||||
|
||||
### And Plenty More!
|
||||
|
||||
Rocket v0.2 is full of many new features! In addition to the three features
|
||||
described above, v0.2 also includes the following:
|
||||
|
||||
* `Config` structures can be built via `ConfigBuilder`, which follows the
|
||||
builder pattern.
|
||||
* Logging can be enabled or disabled on custom configuration via a second
|
||||
parameter to the `Rocket::custom` method.
|
||||
* `name` and `value` methods were added to `Header` to retrieve the name and
|
||||
value of a header.
|
||||
* A new configuration parameter, `workers`, can be used to set the number of
|
||||
threads Rocket uses.
|
||||
* The address of the remote connection is available via `Request.remote()`.
|
||||
Request preprocessing overrides remote IP with value from the `X-Real-IP`
|
||||
header, if present.
|
||||
* During testing, the remote address can be set via `MockRequest.remote()`.
|
||||
* The `SocketAddr` request guard retrieves the remote address.
|
||||
* A `UUID` type has been added to `contrib`.
|
||||
* `rocket` and `rocket_codegen` will refuse to build with an incompatible
|
||||
nightly version and emit nice error messages.
|
||||
* Major performance and usability improvements were upstreamed to the `cookie`
|
||||
crate, including the addition of a `CookieBuilder`.
|
||||
* When a checkbox isn't present in a form, `bool` types in a `FromForm`
|
||||
structure will parse as `false`.
|
||||
* The `FormItems` iterator can be queried for a complete parse via `completed`
|
||||
and `exhausted`.
|
||||
* Routes for `OPTIONS` requests can be declared via the `options` decorator.
|
||||
* Strings can be percent-encoded via `URI::percent_encode()`.
|
||||
|
||||
## Breaking Changes
|
||||
|
||||
This release includes several breaking changes. These changes are listed below
|
||||
along with a short note about how to handle the breaking change in existing
|
||||
applications.
|
||||
|
||||
* **`Rocket::custom` takes two parameters, the first being `Config` by
|
||||
value.**
|
||||
|
||||
A call in v0.1 of the form `Rocket::custom(&config)` is now
|
||||
`Rocket::custom(config, false)`.
|
||||
|
||||
* **Tera templates are named without their extension.**
|
||||
|
||||
A templated named `name.html.tera` is now simply `name`.
|
||||
|
||||
* **`JSON` `unwrap` method has been renamed to `into_inner`.**
|
||||
|
||||
A call to `.unwrap()` should be changed to `.into_inner()`.
|
||||
|
||||
* **The `map!` macro was removed in favor of the `json!` macro.**
|
||||
|
||||
A call of the form `map!{ "a" => b }` can be written as: `json!({ "a": b
|
||||
})`.
|
||||
|
||||
* **The `hyper::SetCookie` header is no longer exported.**
|
||||
|
||||
Use the `Cookie` type as an `Into<Header>` type directly.
|
||||
|
||||
* **The `Content-Type` for `String` is now `text/plain`.**
|
||||
|
||||
Use `content::HTML<String>` for HTML-based `String` responses.
|
||||
|
||||
* **`Request.content_type()` returns an `Option<ContentType>`.**
|
||||
|
||||
Use `.unwrap_or(ContentType::Any)` to get the old behavior.
|
||||
|
||||
* **The `ContentType` request guard forwards when the request has no
|
||||
`Content-Type` header.**
|
||||
|
||||
Use an `Option<ContentType>` and `.unwrap_or(ContentType::Any)` for the old
|
||||
behavior.
|
||||
|
||||
* **A `Rocket` instance must be declared _before_ a `MockRequest`.**
|
||||
|
||||
Change the order of the `rocket::ignite()` and `MockRequest::new()` calls.
|
||||
|
||||
* **A route with `format` specified only matches requests with the same
|
||||
format.**
|
||||
|
||||
Previously, a route with a `format` would match requests without a format
|
||||
specified. There is no workaround to this change; simply specify formats
|
||||
when required.
|
||||
|
||||
* **`FormItems` can no longer be constructed directly.**
|
||||
|
||||
Instead of constructing as `FormItems(string)`, construct as
|
||||
`FormItems::from(string)`.
|
||||
|
||||
* **`from_from_string(&str)` in `FromForm` removed in favor of
|
||||
`from_form_items(&mut FormItems)`.**
|
||||
|
||||
Most implementation should be using `FormItems` internally; simply use the
|
||||
passed in `FormItems`. In other cases, the form string can be retrieved via
|
||||
the `inner_str` method of `FormItems`.
|
||||
|
||||
* **`Config::{set, default_for}` are deprecated.**
|
||||
|
||||
Use the `set_{param}` methods instead of `set`, and `new` or `build` in
|
||||
place of `default_for`.
|
||||
|
||||
* **Route paths must be absolute.**
|
||||
|
||||
Prepend a `/` to convert a relative path into an absolute one.
|
||||
|
||||
* **Route paths cannot contain empty segments.**
|
||||
|
||||
Remove any empty segments, including trailing ones, from a route path.
|
||||
|
||||
## Bug Fixes
|
||||
|
||||
Three bugs were fixed in this release:
|
||||
|
||||
* Handlebars partials were not properly registered
|
||||
([#122](https://github.com/SergioBenitez/Rocket/issues/122)).
|
||||
* `Rocket::custom` did not set the custom configuration as the `active`
|
||||
configuration.
|
||||
* Route path segments with more than one dynamic parameter were erroneously
|
||||
allowed.
|
||||
|
||||
## General Improvements
|
||||
|
||||
In addition to new features, Rocket saw the following smaller improvements:
|
||||
|
||||
* Rocket no longer overwrites a catcher's response status.
|
||||
* The `port` `Config` type is now a proper `u16`.
|
||||
* Clippy issues injected by codegen are resolved.
|
||||
* Handlebars was updated to `0.25`.
|
||||
* The `PartialEq` implementation of `Config` doesn't consider the path or
|
||||
session key.
|
||||
* Hyper dependency updated to `0.10`.
|
||||
* The `Error` type for `JSON as FromData` has been exposed as `SerdeError`.
|
||||
* SVG was added as a known Content-Type.
|
||||
* Serde was updated to `0.9`.
|
||||
* Form parse failure now results in a **422** error code.
|
||||
* Tera has been updated to `0.7`.
|
||||
* `pub(crate)` is used throughout to enforce visibility rules.
|
||||
* Query parameters in routes (`/path?<param>`) are now logged.
|
||||
* Routes with and without query parameters no longer _collide_.
|
||||
|
||||
Rocket v0.2 also includes all of the new features, bug fixes, and improvements
|
||||
from versions 0.1.1 through 0.1.6. You can read more about these changes in the
|
||||
[v0.1
|
||||
CHANGELOG](https://github.com/SergioBenitez/Rocket/blob/v0.1/CHANGELOG.md).
|
||||
|
||||
## What's next?
|
||||
|
||||
Work now begins on Rocket v0.3! The focus of the next major release will be on
|
||||
security. In particular, three major security features are planned:
|
||||
|
||||
1. **Automatic CSRF protection across all payload-based requests
|
||||
([#14](https://github.com/SergioBenitez/Rocket/issues/14)).**
|
||||
|
||||
Rocket will automatically check the origin of requests made for HTTP `PUT`,
|
||||
`POST`, `DELETE`, and `PATCH` requests, allowing only authorized requests to
|
||||
be dispatched. This includes checking `POST`s from form submissions and any
|
||||
requests made via JavaScript.
|
||||
|
||||
2. **Encryption and signing of session-based cookies
|
||||
([#20](https://github.com/SergioBenitez/Rocket/issues/20)).**
|
||||
|
||||
Built-in session support will encrypt and sign cookies using a user supplied
|
||||
`session_key`. Encryption and signing will occur automatically for
|
||||
session-based cookies.
|
||||
|
||||
3. **Explicit typing of raw HTTP data strings
|
||||
([#43](https://github.com/SergioBenitez/Rocket/issues/43)).**
|
||||
|
||||
A present, the standard `&str` type is used to represent raw HTTP data
|
||||
strings. In the next release, a new type, `&RawStr`, will be used for this
|
||||
purpose. This will make it clear when raw data is being handled. The type
|
||||
will expose convenient methods such as `.url_decode()` and `.html_escape()`.
|
||||
|
||||
Work on Rocket v0.3 will also involve exploring built-in support for user
|
||||
authentication and authorization as well as automatic parsing of multipart
|
||||
forms.

# Rocket v0.3: Fairings, TLS, Private Cookies
|
||||
|
||||
<p class="metadata"><strong>
|
||||
Posted by <a href="https://sergio.bz">Sergio Benitez</a> on July 14, 2017
|
||||
</strong></p>
|
||||
|
||||
I'm excited to announce that the next major release of Rocket is available
|
||||
today! Rocket 0.3 is packed with new features and improvements that increase
|
||||
developer productivity, improve application security, and provide new
|
||||
opportunities for extensibility. Rocket 0.3 is the culmination of almost 6
|
||||
months of work. During this time, more than 225 changes were committed, over 100
|
||||
issues (primarily questions and feature requests) were closed, and over 40 pull
|
||||
requests were submitted. The Rocket community has proven steadfast in their
|
||||
support: a sincere thank you to everyone involved!
|
||||
|
||||
## About Rocket
|
||||
|
||||
Rocket is a web framework for Rust with a focus on ease of use, expressibility,
|
||||
and speed. Rocket makes it simple to write fast web applications without
|
||||
sacrificing flexibility or type safety. All with minimal code.
|
||||
|
||||
Not already using Rocket? Join the thousands of users and dozens of companies
|
||||
happily using Rocket today! Rocket's extensive documentation makes it easy. Get
|
||||
started now by [reading through the guide](../../guide) or learning more from
|
||||
[the overview](../../overview).
|
||||
|
||||
## What's New?
|
||||
|
||||
Rocket 0.3 is a _big_ release, packed with over 100 changes. We highlight the
|
||||
biggest new features here. For a complete description of everything new and
|
||||
different in 0.3, please see the [CHANGELOG].
|
||||
|
||||
[CHANGELOG]: https://github.com/SergioBenitez/Rocket/blob/v0.3.0/CHANGELOG.md#version-030-jul-14-2017
|
||||
|
||||
### Fairings
|
||||
|
||||
Fairings bring structured middleware to Rocket. With fairings, Rocket
|
||||
applications can hook into the application lifecycle to record or rewrite
|
||||
information about incoming requests, outgoing responses, and the Rocket
|
||||
application itself.
|
||||
|
||||
Rocket's fairings are a lot like middleware from other frameworks, but they bear
|
||||
a few key distinctions:
|
||||
|
||||
* Fairings cannot directly terminate or respond to an incoming request.
|
||||
* Fairings cannot inject arbitrary, non-request data into a request.
|
||||
* Fairings _can_ prevent an application from launching.
|
||||
* Fairings _can_ inspect and modify the application's configuration.
|
||||
|
||||
Fairings are implemented through Rocket's [`Fairing`] trait. The trait consists
|
||||
of callback methods that Rocket invokes as needed. A fairing can subscribe to
|
||||
receive callbacks for the following four events:
|
||||
|
||||
* **Attach**: called when a fairing is first registered.
|
||||
* **Launch**: called immediately before the Rocket application launches.
|
||||
* **Request**: called just after a request is received.
|
||||
* **Response**: called when a response is ready to be returned.
|
||||
|
||||
The new [fairings guide] describes fairings in detail, expands on their
|
||||
limitations and abilities, and includes implementation examples. I encourage you
|
||||
to experiment with fairings and report your experiences. As always, feedback is
|
||||
instrumental in solidifying a robust design.
|
||||
|
||||
[`Fairing`]: @api/rocket/fairing/trait.Fairing.html
|
||||
[fairings guide]: ../../guide/fairings
|
||||
|
||||
### Native TLS Support
|
||||
|
||||
Rocket 0.3 includes built-in, experimental support for TLS, powered by
|
||||
[`rustls`]. To enable TLS support, compile Rocket with the `tls` feature
|
||||
enabled. Then, configure file paths to an RSA certificate chain and
|
||||
corresponding private key in the `Rocket.toml` file or via environment
|
||||
variables:
|
||||
|
||||
```toml
|
||||
[global.tls]
|
||||
certs = "/path/to/certs.pem"
|
||||
key = "/path/to/key.pem"
|
||||
```
|
||||
|
||||
TLS support in Rocket is experimental and not yet recommended for general use
|
||||
over the internet. Instead, prefer to place Rocket behind a mature reverse-proxy
|
||||
such as NGINX. That being said, use of Rocket's TLS support is encouraged for
|
||||
local networking (such as local-only IoT devices) or as required during
|
||||
development.
|
||||
|
||||
For more details on Rocket's TLS support, see the [configuring TLS] section of
|
||||
the guide.
|
||||
|
||||
[`rustls`]: https://github.com/ctz/rustls
|
||||
[configuring TLS]: ../../guide/configuration/#configuring-tls
|
||||
|
||||
### Private Cookies
|
||||
|
||||
In Rocket 0.3, cookies can be _private_. Private cookies are encrypted using
|
||||
authenticated encryption, a form of encryption which simultaneously provides
|
||||
confidentiality, integrity, and authenticity. This means that private cookies
|
||||
cannot be inspected, tampered with, or manufactured by clients.
|
||||
|
||||
Retrieving, adding, and removing private cookies is done via the new
|
||||
[`get_private`], [`add_private`], and [`remove_private`] methods on the
|
||||
[`Cookies`] type. As an example, consider the code below which sets and
|
||||
retrieves a `user_id` private cookie in two routes:
|
||||
|
||||
```rust
|
||||
/// Retrieve the user's ID, if any.
|
||||
#[get("/user_id")]
|
||||
fn user_id(cookies: Cookies) -> Option<String> {
|
||||
request.cookies()
|
||||
.get_private("user_id")
|
||||
.map(|cookie| format!("User ID: {}", cookie.value()))
|
||||
}
|
||||
|
||||
/// Remove the `user_id` cookie.
|
||||
#[post("/logout")]
|
||||
fn logout(mut cookies: Cookies) -> Flash<Redirect> {
|
||||
cookies.remove_private(Cookie::named("user_id"));
|
||||
Flash::success(Redirect::to("/"), "Successfully logged out.")
|
||||
}
|
||||
```
|
||||
|
||||
To encrypt private cookies, Rocket uses the 256-bit key specified in the
|
||||
`secret_key` configuration parameter. If one is not specified, Rocket
|
||||
automatically generates a fresh key at launch.
|
||||
|
||||
For more details on private cookies, see the [private cookies] section of the
|
||||
guide.

||||

||||

|
||||
[`get_private`]: @api/rocket/http/enum.Cookies.html#method.get_private
|
||||
[`add_private`]: @api/rocket/http/enum.Cookies.html#method.add_private
|
||||
[`remove_private`]: @api/rocket/http/enum.Cookies.html#method.remove_private
|
||||
[private cookies]: ../../guide/requests/#private-cookies
|
||||
|
||||
### Form Field Naming
|
||||
|
||||
In 0.2 and below, Rocket always matches form field names to structure field
|
||||
names exactly when deriving [`FromForm`]. This presented an issue when an
|
||||
invalid Rust identifier was used as a form field's name. For example, it was not
|
||||
possible to represent a form with a field name of "type" since `type` is a
|
||||
keyword and thus an illegal identifier. The following resulted in a compile-time
|
||||
error:
|
||||
|
||||
```rust
|
||||
#[derive(FromForm)]
|
||||
struct External {
|
||||
type: String
|
||||
}
|
||||
```
|
||||
|
||||
In Rocket 0.3, you can ask Rocket to match against a different form field for a
|
||||
given structure field by using the `#[form(field = "name")]` field annotation.
|
||||
As a result, the "type" form field can now be captured using something like the
|
||||
following:
|
||||
|
||||
```rust
|
||||
#[derive(FromForm)]
|
||||
struct External {
|
||||
#[form(field = "type")]
|
||||
api_type: String
|
||||
}
|
||||
```
|
||||
|
||||
Rocket will automatically match the form field named "type" to the structure
|
||||
field named `api_type`. For more details on form field naming, see the [field
|
||||
renaming](../../guide/requests/#field-renaming) section of the guide.
|
||||
|
||||
[`FromForm`]: @api/rocket/request/trait.FromForm.html
|
||||
|
||||
### And Plenty More!
|
||||
|
||||
In addition to the four highlighted above, Rocket 0.3 also ships with the
|
||||
following new features:
|
||||
|
||||
* A [`MsgPack`] type has been added for simple consumption and returning of
|
||||
MessagePack data.
|
||||
* [`Rocket::launch()`] returns launch failures ([`LaunchError`]) for
|
||||
inspection without panicking.
|
||||
* Routes without query parameters now match requests with or without query
|
||||
parameters.
|
||||
* [Default rankings] prefer static paths and routes with query string matches.
|
||||
* A native [`Accept`] header structure was added.
|
||||
* The [`Accept`] request header can be retrieved via [`Request::accept()`].
|
||||
* All active routes can be retrieved via [`Rocket::routes()`].
|
||||
* [`Response::body_string()`] was added to retrieve the response body as a
|
||||
`String`.
|
||||
* [`Response::body_bytes()`] was added to retrieve the response body as a
|
||||
`Vec<u8>`.
|
||||
* [`Response::content_type()`] was added to retrieve the Content-Type header
|
||||
of a response.
|
||||
* Data limits on incoming data are [now
|
||||
configurable](../../guide/configuration/#data-limits).
|
||||
* [`Request::limits()`] was added to retrieve incoming data limits.
|
||||
* Responders may dynamically adjust their response based on the incoming
|
||||
request.
|
||||
* [`Request::guard()`] was added for simple retrieval of request guards.
|
||||
* [`Request::route()`] was added to retrieve the active route, if any.
|
||||
* [`&Route`] is now a request guard.
|
||||
* The base mount path of a [`Route`] can be retrieved via `Route::base` or
|
||||
`Route::base()`.
|
||||
* `Config::{development, staging, production}` constructors were added for
|
||||
[`Config`].
|
||||
* [`Config::get_datetime()`] was added to retrieve an extra as a `Datetime`.
|
||||
* Forms can be now parsed _leniently_ via the new [`LenientForm`] data guard.
|
||||
* The `?` operator can now be used with `Outcome`.
|
||||
* Quoted string, array, and table [configuration parameters] can be set via
|
||||
environment variables.
|
||||
* Log coloring is disabled when `stdout` is not a TTY.
|
||||
* [`FromForm`] is implemented for `Option<T: FromForm>`, `Result<T: FromForm,
|
||||
T::Error>`.
|
||||
* The [`NotFound`] responder was added for simple **404** response
|
||||
construction.

## Breaking Changes
|
||||
|
||||
This release includes many breaking changes such as support for `serde` 1.0. To
|
||||
keep this release note short, please see the
|
||||
[CHANGELOG](https://github.com/SergioBenitez/Rocket/blob/v0.3.0/CHANGELOG.md#breaking-changes)
|
||||
for the full list of breaking changes along with a short note about how to
|
||||
handle the breaking change in existing applications.
|
||||
|
||||
## General Improvements
|
||||
|
||||
In addition to new features, Rocket saw the following improvements:
|
||||
|
||||
* "Rocket" is now capitalized in the `Server` HTTP header.
|
||||
* The generic parameter of `rocket_contrib::Json` defaults to `json::Value`.
|
||||
* The trailing '...' in the launch message was removed.
|
||||
* The launch message prints regardless of the config environment.
|
||||
* For debugging, `FromData` is implemented for `Vec<u8>` and `String`.
|
||||
* The port displayed on launch is the port resolved, not the one configured.
|
||||
* The `uuid` dependency was updated to `0.5`.
|
||||
* The `base64` dependency was updated to `0.6`.
|
||||
* The `toml` dependency was updated to `0.4`.
|
||||
* The `handlebars` dependency was updated to `0.27`.
|
||||
* The `tera` dependency was updated to `0.10`.
|
||||
* [`yansi`] is now used for all terminal coloring.
|
||||
* The `dev` `rustc` release channel is supported during builds.
|
||||
* [`Config`] is now exported from the root.
|
||||
* [`Request`] implements `Clone` and `Debug`.
|
||||
* The `workers` config parameter now defaults to `num_cpus * 2`.
|
||||
* Console logging for table-based config values is improved.
|
||||
* `PartialOrd`, `Ord`, and `Hash` are now implemented for [`State`].
|
||||
* The format of a request is always logged when available.

## What's Next?
|
||||
|
||||
Rocket 0.4, of course! The focus of the next major release is two-fold: security
|
||||
and usability. The following major features are planned:
|
||||
|
||||
1. **Automatic CSRF protection across all payload-based requests
|
||||
([#14](https://github.com/SergioBenitez/Rocket/issues/14)).**
|
||||
|
||||
This is a carry-over from the 0.3 wishlist. Rocket will automatically check
|
||||
the origin of requests made for HTTP `PUT`, `POST`, `DELETE`, and `PATCH`
|
||||
requests, allowing only valid requests to be dispatched. This includes
|
||||
checking form submissions and requests made via JavaScript.
|
||||
|
||||
2. **First-class database support
|
||||
([#167](https://github.com/SergioBenitez/Rocket/issues/167)).**
|
||||
|
||||
Connecting a database to Rocket is presently [much wordier than necessary].
|
||||
The plan for 0.4 is to minimize the amount of effort. At most, a couple of
|
||||
lines of configuration and a single line of initialization code should be
|
||||
required.
|
||||
|
||||
3. **Typed URL generation from routes
|
||||
([#263](https://github.com/SergioBenitez/Rocket/issues/263)).**
|
||||
|
||||
Explicitly writing URLs is error-prone. Because routes are fully-typed in
|
||||
Rocket, it's possible to check that a URL corresponding to a route
|
||||
type-checks. In the next release, a `url!` macro will be available to
|
||||
automatically generate URLs for routes in a type-safe manner.

## What's New?
|
||||
|
||||
Rocket 0.4 is the largest release to date by a _wide_ margin. It is packed with
|
||||
hundreds of changes. We highlight the largest of them here. For a complete
|
||||
description of everything new and different in 0.4, please see the [CHANGELOG].
|
||||
|
||||
[CHANGELOG]: https://github.com/SergioBenitez/Rocket/blob/v0.4.0/CHANGELOG.md#version-040-dec-06-2018
|
||||
|
||||
### Maintainers += 1
|
||||
|
||||
An open source project is as much about the people as it is about the code. This
|
||||
is why I am delighted to welcome [@jebrosen] as Rocket's first co-maintainer!
|
||||
Jeb is directly responsible for several of the new features in 0.4, has
|
||||
painstakingly code reviewed many other changes, and actively answers questions
|
||||
and resolves issues on GitHub, IRC, and offline.
|
||||
|
||||
Needless to say, Rocket is a better project thanks to you, Jeb. Welcome!
|
||||
|
||||
[@jebrosen]: https://github.com/jebrosen
|
||||
|
||||
### Codegen Rewrite
|
||||
|
||||
In 0.4, the [`rocket_codegen`] crate has been entirely rewritten to use
|
||||
to-be-stable procedural macro APIs where it previously used private, unstable
|
||||
`rustc` APIs. While this is largely an internal change, it has big, positive
|
||||
implications for all Rocket users.
|
||||
|
||||
First and foremost, the path to Rocket on stable is now clearly in sight. While
|
||||
there are still hurdles to overcome, we are actively working with the Rust team
|
||||
to make Rocket on stable a reality as soon as possible. We expect the next major
|
||||
Rocket release to support the stable channel.
|
||||
|
||||
Second, but equally important, we expect breakages due to nightly changes to
|
||||
drop dramatically, likely to zero. This means that Rocket is largely already
|
||||
_de-facto_ toolchain stable.
|
||||
|
||||
The new prelude import for Rocket applications is:
|
||||
|
||||
```diff
|
||||
- #![feature(plugin)]
|
||||
- #![plugin(rocket_codegen)]
|
||||
+ #![feature(proc_macro_hygiene, decl_macro)]
|
||||
|
||||
- extern crate rocket;
|
||||
+ #[macro_use] extern crate rocket;
|
||||
```
|
||||
|
||||
[`rocket_codegen`] should **_not_** be a direct dependency. Remove it from your
|
||||
`Cargo.toml`:
|
||||
|
||||
```diff
|
||||
[dependencies]
|
||||
- rocket = "0.3"
|
||||
+ rocket = "0.4"
|
||||
- rocket_codegen = "0.3"
|
||||
```
|
||||
|
||||
[`rocket_codegen`]: https://api.rocket.rs/v0.4/rocket_codegen/index.html
|
||||
|
||||
### Typed URIs
|
||||
|
||||
Rocket 0.4 introduces the [`uri!`] macro, allowing you to construct URIs to
|
||||
routes in a robust, type-safe, and URI-safe manner. Type or route parameter
|
||||
mismatches are caught at compile-time, and changes to route URIs are
|
||||
automatically reflected in the generated URIs.
|
||||
|
||||
To illustrate, consider the following route:
|
||||
|
||||
```rust
|
||||
#[get("/person/<name>?<age>")]
|
||||
fn person(name: String, age: Option<u8>)
|
||||
```
|
||||
|
||||
URIs to this `person` route can be created as follows:
|
||||
|
||||
```rust
|
||||
// with unnamed parameters, in route URI declaration order
|
||||
let uri = uri!(person: "Mike Smith", 28);
|
||||
assert_eq!(uri.to_string(), "/person/Mike%20Smith?age=28");
|
||||
|
||||
// with named parameters, order irrelevant
|
||||
let uri = uri!(person: name = "Mike", age = 28);
|
||||
let uri = uri!(person: age = 28, name = "Mike");
|
||||
assert_eq!(uri.to_string(), "/person/Mike?age=28");
|
||||
|
||||
// with a specific mount-point
|
||||
let uri = uri!("/api", person: name = "Mike", age = 28);
|
||||
assert_eq!(uri.to_string(), "/api/person/Mike?age=28");
|
||||
|
||||
// with optional query parameters ignored
|
||||
let uri = uri!(person: "Mike", _);
|
||||
let uri = uri!(person: name = "Mike", age = _);
|
||||
assert_eq!(uri.to_string(), "/person/Mike");
|
||||
```
|
||||
|
||||
Should your route's URI change in an incompatible manner, or should you mistype
|
||||
parameters, Rocket informs you of the error at compile-time with a helpful
|
||||
message:
|
||||
|
||||
```rust
|
||||
error: person route uri expects 2 parameters but 1 was supplied
|
||||
--> examples/uri/src/main.rs:9:29
|
||||
|
|
||||
9 | uri!(person: "Mike Smith");
|
||||
| ^^^^^^^^^^^^
|
||||
|
|
||||
= note: expected parameters: name: String, age: Option<u8>
|
||||
```
|
||||
|
||||
The same applies to type errors: Rocket informs you of any type errors at
|
||||
compile-time as well:
|
||||
|
||||
```rust
|
||||
error: the trait bound u8: FromUriParam<Query, &str> is not satisfied
|
||||
--> examples/uri/src/main.rs:9:35
|
||||
|
|
||||
9 | uri!(person: age = "10", name = "Mike");
|
||||
| ^^^^ FromUriParam<Query, &str> is not implemented for u8
|
||||
|
|
||||
```
|
||||
|
||||
We recommend that `uri!` is exclusively used when constructing route URIs. For
|
||||
more information on typed URIs, see the new [Typed URIs] guide section and the
|
||||
[`uri!`] macro documentation.
|
||||
|
||||
[`uri!`]: @api/rocket_codegen/macro.uri.html
|
||||
[Typed URIs]: ../../guide/responses/#typed-uris
|
||||
|
||||
### Database Support
|
||||
|
||||
Rocket now includes built-in, ORM-agnostic support for database connection
|
||||
pooling. More specifically, Rocket allows you to easily configure and connect
|
||||
your Rocket application to databases through connection pools in three simple,
|
||||
largely automated steps:
|
||||
|
||||
1. Configure databases in `Rocket.toml`.
|
||||
2. Associate a request guard type and fairing with each database.
|
||||
3. Use the request guard to retrieve a connection in a handler.
|
||||
|
||||
As an example, for a Diesel-based SQLite database named `sqlite_logs`, your
|
||||
`Rocket.toml` would record the URL to the database in the `databases` table:
|
||||
|
||||
```toml
|
||||
[global.databases]
|
||||
sqlite_logs = { url = "/path/to/database.sqlite" }
|
||||
```
|
||||
|
||||
In the application, a unit-like `struct` with one internal type (the database
|
||||
connection) is decorated with the `#[database]` attribute and the name of the
|
||||
configured database. This generates a fairing which must then be attached:
|
||||
|
||||
```rust
|
||||
#[database("sqlite_logs")]
|
||||
struct LogsDbConn(diesel::SqliteConnection);
|
||||
|
||||
rocket::ignite().attach(LogsDbConn::fairing())
|
||||
```
|
||||
|
||||
That's it! Whenever a connection to the database is needed, the type can be used
|
||||
as a request guard:
|
||||
|
||||
```rust
|
||||
#[get("/logs/<id>")]
|
||||
fn get_logs(conn: LogsDbConn, id: usize) -> Result<Logs> {
|
||||
logs::filter(id.eq(log_id)).load(&conn)
|
||||
}
|
||||
```
|
||||
|
||||
For more information on Rocket's database support, see the new [Database] guide
|
||||
section and the [`rocket_contrib::databases`] module documentation.
|
||||
|
||||
[Database]: ../../guide/state/#databases
|
||||
[`rocket_contrib::databases`]: @api/rocket_contrib/databases/index.html
|
||||
|
||||
### Revamped Queries
|
||||
|
||||
In Rocket 0.4, query string handling has been completely overhauled, resolving
|
||||
some of the most called for requests in Rocket's history ([#608]). The new query
|
||||
handling route syntax and semantics were designed with the following goals in
|
||||
mind:
|
||||
|
||||
* Enable matching of static query components.
|
||||
* No special-casing of any kind, preferring type-driven flows.
|
||||
* Ad-hoc matching of specific query key/value pairs.
|
||||
* Lenient parsing by default, allowing missing parameters.
|
||||
* Order-independent matching of query parameters.
|
||||
|
||||
To illustrate the new system in action, consider the following route:
|
||||
|
||||
```rust
|
||||
#[derive(FromForm)]
|
||||
struct DogDetails {
|
||||
color: Color,
|
||||
height: Inches,
|
||||
weight: Pounds
|
||||
}
|
||||
|
||||
#[get("/animal?dog&<name>&<nickname>&<rest..>")]
|
||||
fn dog(name: String, nickname: Option<String>, rest: Form<DogDetails>)
|
||||
```
|
||||
|
||||
This route matches any `GET` request with a path of `/animal`, a static query
|
||||
component of `dog`, and key/value parameters of `color`, `height`, and `weight`
|
||||
that validate as `Color`, `Inches`, and `Pounds`, respectively. Furthermore, it
|
||||
optionally accepts a key/value parameter of `nickname`. If the value is present,
|
||||
`nickname` will be `Some`; if it is not, `nickname` will be `None`.
|
||||
|
||||
Single parameters (`<param>`) like `name` and `nickname` are validated using the
|
||||
existing [`FromFormValue`] trait while trailing parameters (`<param..>`) are
|
||||
validated using the new [`FromQuery`] trait. Both traits are user implementable,
|
||||
and [`FromFormValue`] can be derived.
|
||||
|
||||
For more details on handling query strings, see the new [Query Strings] guide
|
||||
section and the updated [`route` attribute] documentation.

||||

||||

|
||||
[Query Strings]: ../../guide/requests/#query-strings
|
||||
[#608]: https://github.com/SergioBenitez/Rocket/issues/608
|
||||
|
||||
### Stateful Handlers
|
||||
|
||||
The type of a handler has been generalized in 0.4 to any type that implements
|
||||
the new [`Handler`] trait. Among other things, this allows handlers to refer to
|
||||
internal state during request handling.
|
||||
|
||||
The new [`StaticFiles`] `contrib` type uses this functionality to provide
|
||||
easier-than-ever static file serving. For example, to make local files from a
|
||||
`/static` directory accessible at `/public`, you need simply write:
|
||||
|
||||
|
||||
```rust
|
||||
fn main() {
|
||||
rocket::ignite()
|
||||
.mount("/public", StaticFiles::from("/static"))
|
||||
.launch();
|
||||
}
|
||||
```
|
||||
|
||||
We encourage users to explore the new `Handler` API and contribute libraries
|
||||
with pluggable handlers! For more details, see the [`Handler`] documentation.
|
||||
|
||||
[`Handler`]: @api/rocket/trait.Handler.html
|
||||
[`StaticFiles`]: @api/rocket_contrib/serve/struct.StaticFiles.html
|
||||
|
||||
### Responder Derive
|
||||
|
||||
In Rocket 0.4, the [`Responder`] trait can be derived for `enum`s and `struct`s
|
||||
with named fields. This greatly simplifies returning multiple types of responses
|
||||
from a single handler.
|
||||
|
||||
To illustrate, consider a route that returns either a `Json<Info>` structure for
|
||||
401 (unauthorized) errors or a `NamedFile` with a dynamic Content-Type for 404
|
||||
(not found) errors. To accomplish this previously, `Result` values could be
|
||||
arbitrarily nested, an unappealing and semantically incorrect approach.
|
||||
Alternatively, an `enum` could be declared with the appropriate variants, and
|
||||
`Responder` could be manually implemented for the `enum`. As of 0.4, that
|
||||
implementation can be automatically derived:
|
||||
|
||||
```rust
|
||||
#[derive(Responder, Debug)]
|
||||
enum Error {
|
||||
#[response(status = 401)]
|
||||
Unauthorized(Json<Info>),
|
||||
#[response(status = 404)]
|
||||
NotFound(NamedFile, ContentType),
|
||||
}
|
||||
```
|
||||
|
||||
A value of this type can then be returned from a hander or used as part of
|
||||
wrapping responders:
|
||||
|
||||
```rust
|
||||
#[get("/<item>")]
|
||||
fn handler(user: Option<User>, item: Option<Item>) -> Result<T, Error> {
|
||||
if user.is_none() {
|
||||
Err(Error::Unauthorized(..))
|
||||
} else if item.is_none() {
|
||||
Err(Error::NotFound(..))
|
||||
} else {
|
||||
Ok(..)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The status for each variant will be automatically set to the value of the
|
||||
`status` variant attribute, and fields beyond the first will be added as
|
||||
headers to the response (here, `ContentType`).
|
||||
|
||||
For more on using the `Responder` derive, see the new [Custom Responders] guide
|
||||
section and the [`Responder` derive] documentation.

### Live Template Reloading
|
||||
|
||||
Rocket 0.4 automatically reloads changed templates at runtime without requiring
|
||||
recompilation. This works on all major platforms. For security and performance
|
||||
reasons, live template reloading is only enabled when the application is
|
||||
compiled in debug mode.
|
||||
|
||||
There is no configuration necessary: this _just works_ out of the box!
|
||||
|
||||
### And Plenty More!
|
||||
|
||||
In addition to the features highlighted above, Rocket 0.4 also contains the
|
||||
following new features:
|
||||
|
||||
* Introduced [Request-Local State].
|
||||
* Introduced [transforming] data guards via [`FromData::transform()`].
|
||||
* Introduced the [`SpaceHelmet`] security and privacy headers fairing.
|
||||
* Private cookies are gated behind a `private-cookies` default feature.
|
||||
* Added [derive for `FromFormValue`].
|
||||
* Added [`Template::custom()`] for customizing templating engines.
|
||||
* Cookies are automatically tracked and propagated by [`Client`].
|
||||

|
||||
[`LocalRequest::private_cookie()`].
|
||||

|
||||
* Keep-alive can be configured via the `keep_alive` configuration parameter.
|
||||
* Allow CLI colors and emoji to be disabled with `ROCKET_CLI_COLORS=off`.

## General Improvements
|
||||
|
||||
In addition to new features, Rocket saw the following improvements:
|
||||
|
||||
* Log messages now refer to routes by name.
|
||||
* Collision errors on launch name the colliding routes.
|
||||
* Launch fairing failures refer to the failing fairing by name.
|
||||

|
||||
week by default.
|
||||
* A [Tera templates example] was added.
|
||||
* All macros, derives, and attributes are individually documented in
|
||||
[`rocket_codegen`].
|
||||

|
||||
* Configuration information is logged in all environments.
|
||||

|
||||
* [`FormItems`] now parses empty keys and values as well as keys without
|
||||
values.
|
||||
* Added [`Config::active()`] as a shorthand for

||||
`Config::new(Environment::active()?)`.
|
||||
* Address/port binding errors at launch are detected and explicitly emitted.
|
||||

||||
* Added [`Config::root_relative()`] for retrieving paths relative to the
|
||||
configuration file.
|
||||
* Added [`Config::tls_enabled()`] for determining whether TLS is actively
|
||||
enabled.
|
||||
* ASCII color codes are not emitted on versions of Windows that do not support
|
||||
them.
|
||||
* Added FLAC (`audio/flac`), Icon (`image/x-icon`), WEBA (`audio/webm`), TIFF
|
||||
(`image/tiff`), AAC (`audio/aac`), Calendar (`text/calendar`), MPEG
|
||||
(`video/mpeg`), TAR (`application/x-tar`), GZIP (`application/gzip`), MOV
|
||||
(`video/quicktime`), MP4 (`video/mp4`), ZIP (`application/zip`) as known
|
||||
media types.
|
||||
* Added `.weba` (`WEBA`), `.ogv` (`OGG`), `.mp4` (`MP4`), `.mpeg4` (`MP4`),
|
||||
`.aac` (`AAC`), `.ics` (`Calendar`), `.bin` (`Binary`), `.mpg` (`MPEG`),
|
||||
`.mpeg` (`MPEG`), `.tar` (`TAR`), `.gz` (`GZIP`), `.tif` (`TIFF`), `.tiff`
|
||||
(`TIFF`), `.mov` (`MOV`) as known extensions.
|
||||
* Interaction between route attributes and declarative macros has been
|
||||
improved.
|
||||
* Generated code now logs through logging infrastructures as opposed to using
|
||||
`println!`.
|
||||
* Routing has been optimized by caching routing metadata.
|
||||
* [`Form`] and [`LenientForm`] can be publicly constructed.
|
||||
* Console coloring uses default terminal colors instead of white.
|
||||
* Console coloring is consistent across all messages.

|
||||

## What's Next?
|
||||
|
||||
Rocket v0.5 is scheduled to be _at least_ as exciting as 0.4! As always, the
|
||||
focus continues to be usability, stability, security, and performance. With this
|
||||
in mind, the roadmap for 0.5 includes:
|
||||
|
||||
1. **Support for Rust Stable** ([#19])
|
||||
|
||||
Finally! Rocket 0.5 will compile and run on stable versions of the Rust
|
||||
compiler.
|
||||
|
||||
2. **Asynchronous Request Handling** ([#17])
|
||||
|
||||
In 0.5, Rocket will migrate to the latest asynchronous version of `hyper` and
|
||||
`futures` with compatibility for `async`/`await` syntax. Of utmost importance
|
||||
is preserving Rocket's usability. As such, these changes will be largely
|
||||
internal, with asynchronous I/O peeking over the covers _only_ when
|
||||
explicitly desired or required. As a side effect, we expect a substantial
|
||||
performance boost from the migration as well as resolution to long-standing
|
||||
issues.
|
||||
|
||||
3. **Multipart Form Support** ([#106])
|
||||
|
||||
The lack of built-in multipart form support makes handling file uploads and
|
||||
other submissions much more cumbersome than necessary. Rocket 0.5 will
|
||||
generalize its existing forms infrastructure to handle multipart forms.
|
||||
|
||||
4. **Stronger CSRF and XSS Protection** ([#14])
|
||||
|
||||
Since 0.3, Rocket uses `SameSite: Strict` private cookies to prevent CSRF
|
||||
attacks. This technique is only tenable in newer browsers. In 0.5, Rocket
|
||||
will protect against CSRF using more robust techniques. Rocket will also add
|
||||
support for automatic, browser-based XSS protection.

|

Rocket's main task is to route incoming requests to the appropriate request
|
||||
handler using your application's declared routes. Routes are declared using
|
||||
Rocket's _route_ attributes. The attribute describes the requests that match the
|
||||
route. The attribute is placed on top of a function that is the request handler
|
||||
for that route.
|
||||
|
||||
As an example, consider the simple route below:
|
||||
|
||||
```rust
|
||||
#[get("/")]
|
||||
fn index() -> &'static str {
|
||||
"Hello, world!"
|
||||
}
|
||||
```
|
||||
|
||||
This route, named `index`, will match against incoming HTTP `GET` requests to
|
||||
the `/` path, the index. The request handler returns a string. Rocket will use
|
||||
the string as the body of a fully formed HTTP response.
|
||||
'''
|
||||
|
||||
[[panels]]
|
||||
name = "Dynamic Params"
|
||||
content = '''
|
||||
Rocket allows you to interpret segments of a request path dynamically. To
|
||||
illustrate, let's use the following route:
|
||||
|
||||
```rust
|
||||
#[get("/hello/<name>/<age>")]
|
||||
fn hello(name: String, age: u8) -> String {
|
||||
format!("Hello, {} year old named {}!", age, name)
|
||||
}
|
||||
```
|
||||
|
||||
The `hello` route above matches two dynamic path segments declared inside
|
||||
brackets in the path: `<name>` and `<age>`. _Dynamic_ means that the segment can
|
||||
be _any_ value the end-user desires.
|
||||
|
||||
Each dynamic parameter (`name` and `age`) must have a type, here `&str` and
|
||||
`u8`, respectively. Rocket will attempt to parse the string in the parameter's
|
||||
position in the path into that type. The route will only be called if parsing
|
||||
succeeds. To parse the string, Rocket uses the
|
||||
[FromParam](@api/rocket/request/trait.FromParam.html) trait,
|
||||
which you can implement for your own types!

|
||||
Request body data is handled in a special way in Rocket: via the
|
||||
[FromData](@api/rocket/data/trait.FromData.html) trait. Any type that implements
|
||||
`FromData` can be derived from incoming body data. To tell Rocket that you're
|
||||
expecting request body data, the `data` route argument is used with the name of
|
||||
the parameter in the request handler:
|
||||
|
||||
```rust
|
||||
#[post("/login", data = "<user_form>")]
|
||||
fn login(user_form: Form<UserLogin>) -> String {
|
||||
format!("Hello, {}!", user_form.name)
|
||||
}
|
||||
```
|
||||
|
||||
The `login` route above says that it expects `data` of type `Form<UserLogin>` in
|
||||
the `user_form` parameter. The [Form](@api/rocket/request/struct.Form.html) type
|
||||
is a built-in Rocket type that knows how to parse web forms into structures.
|
||||
Rocket will automatically attempt to parse the request body into the `Form` and
|
||||
call the `login` handler if parsing succeeds. Other built-in `FromData` types
|
||||
include [`Data`](@api/rocket/struct.Data.html),
|
||||
[`Json`](@api/rocket_contrib/json/struct.Json.html), and
|
||||
[`Flash`](@api/rocket/response/struct.Flash.html).

||||
'''
|
||||
|

[[panels]]
|
||||
name = "Request Guards"
|
||||
content = '''
|
||||
In addition to dynamic path and data parameters, request handlers can also
|
||||
contain a third type of parameter: _request guards_. Request guards aren't
|
||||
declared in the route attribute, and any number of them can appear in the
|
||||
request handler signature.
|
||||
|
||||
Request guards _protect_ the handler from running unless some set of conditions
|
||||
are met by the incoming request metadata. For instance, if you are writing an
|
||||
API that requires sensitive calls to be accompanied by an API key in the request
|
||||
header, Rocket can protect those calls via a custom `ApiKey` request guard:
|
||||
|
||||
```rust
|
||||
#[get("/sensitive")]
|
||||
fn sensitive(key: ApiKey) { ... }
|
||||
```
|
||||
|
||||
`ApiKey` protects the `sensitive` handler from running incorrectly. In order for
|
||||
Rocket to call the `sensitive` handler, the `ApiKey` type needs to be derived
|
||||
through a [`FromRequest`](@api/rocket/request/trait.FromRequest.html)
|
||||
implementation, which in this case, validates the API key header. Request guards
|
||||
are a powerful and unique Rocket concept; they centralize application policy and
|
||||
invariants through types.
|
||||
'''
|
||||
|
||||
[[panels]]
|
||||
name = "Responders"
|
||||
content = '''
|
||||
The return type of a request handler can be any type that implements
|
||||
[Responder](@api/rocket/response/trait.Responder.html):
|
||||
|
||||
```rust
|
||||
#[get("/")]
|
||||
fn route() -> T { ... }
|
||||
```
|
||||
|
||||
Above, T must implement `Responder`. Rocket implements `Responder` for many of
|
||||
the standard library types including `&str`, `String`, `File`, `Option`, and
|
||||
`Result`. Rocket also implements custom responders such as
|
||||
[Redirect](@api/rocket/response/struct.Redirect.html),
|
||||
[Flash](@api/rocket/response/struct.Flash.html), and
|
||||
[Template](@api/rocket_contrib/templates/struct.Template.html).
|
||||
|
||||
The task of a `Responder` is to generate a
|
||||
[`Response`](@api/rocket/response/struct.Response.html), if possible.
|
||||
`Responder`s can fail with a status code. When they do, Rocket calls the
|
||||
corresponding error catcher, a `catch` route, which can be declared as follows:
|
||||
|
||||
```rust
|
||||
#[catch(404)]
|
||||
fn not_found() -> T { ... }
|
||||
```
|
||||
'''
|
||||
|
||||
[[panels]]
|
||||
name = "Launching"
|
||||
content = '''
|
||||
Launching a Rocket application is the funnest part! For Rocket to begin
|
||||
dispatching requests to routes, the routes need to be _mounted_. After mounting,
|
||||
the application needs to be _launched_. These two steps, usually done in `main`,
|
||||
look like:
|
||||
|
||||
```rust
|
||||
rocket::ignite()
|
||||
.mount("/base", routes![index, another])
|
||||
.launch();
|
||||
```
|
||||
|
||||
The `mount` call takes a base path and a set of routes via the `routes!` macro.
|
||||
The base path (`/base` above) is prepended to the path of every route in the
|
||||
list. This effectively namespaces the routes, allowing for easier composition.
|
||||
|
||||
The `launch` call starts the server. In development, Rocket prints useful
|
||||
information to the console to let you know everything is okay.
|
||||
|
||||
```sh
|
||||
🚀 Rocket has launched from http://localhost:8000
|
||||
```

name = "Validation"
|

color = "blue"
|
||||
content = '''
|
||||
First, Rocket validates a matching request by ensuring that all of the types in
|
||||
a given handler can be derived from the incoming request. If the types cannot be
|
||||
derived, the request is forwarded to the next matching route until a route’s
|
||||
types validate or there are no more routes to try. If all routes fail, a
|
||||
customizable **404** error is returned.
|
||||
|
||||
```rust
|
||||
#[post("/user", data = "<new_user>")]
|
||||
fn new_user(admin: AdminUser, new_user: Form<User>) -> T {
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
For the `new_user` handler above to be called, the following conditions must
|
||||
hold:
|
||||
|
||||
* The request method must be `POST`.
|
||||
* The request path must be `/user`.
|
||||
* The request must contain `data` in its body.
|
||||
* The request metadata must authenticate an `AdminUser`.
|
||||
* The request body must be a form that parses into a `User` struct.

||||

[[steps]]

color = "purple"
|

content = '''
|
||||
Next, the request is processed by an arbitrary handler. This is where most of
|
||||
the business logic in an application resides, and the part of your applications
|
||||
you’ll likely spend the most time writing. In Rocket, handlers are simply
|
||||
functions - that’s it! The only caveat is that the function’s return type must
|
||||
implement the `Responder` trait. The `new_user` function above is an example of
|
||||
a handler.
|
||||
'''
|
||||
|
||||
[[steps]]
|
||||
name = "Response"
|
||||
color = "red"
|
||||
content = '''
|
||||
Finally, Rocket responds to the client by transforming the return value of the
|
||||
handler into an HTTP response. The HTTP response generated from the returned
|
||||
value depends on the type’s specific `Responder` trait implementation.
|
||||
|
||||
```rust
|
||||
fn route() -> T { ... }
|
||||
```
|
||||
|
||||
If the function above is used as a handler, for instance, then the type `T` must
|
||||
implement `Responder`. Rocket provides many useful responder types out of the
|
||||
box. They include:
|
||||
|
||||
* `Json<T>`: Serializes the structure T into JSON and returns it to
|
||||
the client.
|
||||
* `Template`: Renders a template file and returns it to the client.
|
||||
* `Redirect`: Returns a properly formatted HTTP redirect.
|
||||
* `NamedFile`: Streams a given file to the client with the
|
||||
Content-Type taken from the file’s extension.
|
||||
* `Stream`: Streams data to the client from an arbitrary `Read` value.
|
||||
* Many Primitive Types: `String`, `&str`, `File`, `Option`, `Result`, and
|
||||
others all implement the `Responder` trait.
