## Unreleased
|
|
|
|
* The default `NormalizePath` behavior now strips trailing slashes by default. This was
|
|
previously documented to be the case in v3 but the behavior now matches. The effect is that
|
|
routes defined with trailing slashes will become inaccessible when
|
|
using `NormalizePath::default()`.
|
|
|
|
Before: `#[get("/test/")`
|
|
After: `#[get("/test")`
|
|
|
|
Alternatively, explicitly require trailing slashes: `NormalizePath::new(TrailingSlash::Always)`.
|
|
|
|
|
|
## 3.0.0
|
|
|
|
* The return type for `ServiceRequest::app_data::<T>()` was changed from returning a `Data<T>` to
|
|
simply a `T`. To access a `Data<T>` use `ServiceRequest::app_data::<Data<T>>()`.
|
|
|
|
* Cookie handling has been offloaded to the `cookie` crate:
|
|
* `USERINFO_ENCODE_SET` is no longer exposed. Percent-encoding is still supported; check docs.
|
|
* Some types now require lifetime parameters.
|
|
|
|
* The time crate was updated to `v0.2`, a major breaking change to the time crate, which affects
|
|
any `actix-web` method previously expecting a time v0.1 input.
|
|
|
|
* Setting a cookie's SameSite property, explicitly, to `SameSite::None` will now
|
|
result in `SameSite=None` being sent with the response Set-Cookie header.
|
|
To create a cookie without a SameSite attribute, remove any calls setting same_site.
|
|
|
|
* actix-http support for Actors messages was moved to actix-http crate and is enabled
|
|
with feature `actors`
|
|
|
|
* content_length function is removed from actix-http.
|
|
You can set Content-Length by normally setting the response body or calling no_chunking function.
|
|
|
|
* `BodySize::Sized64` variant has been removed. `BodySize::Sized` now receives a
|
|
`u64` instead of a `usize`.
|
|
|
|
* Code that was using `path.<index>` to access a `web::Path<(A, B, C)>`s elements now needs to use
|
|
destructuring or `.into_inner()`. For example:
|
|
|
|
```rust
|
|
// Previously:
|
|
async fn some_route(path: web::Path<(String, String)>) -> String {
|
|
format!("Hello, {} {}", path.0, path.1)
|
|
}
|
|
|
|
// Now (this also worked before):
|
|
async fn some_route(path: web::Path<(String, String)>) -> String {
|
|
let (first_name, last_name) = path.into_inner();
|
|
format!("Hello, {} {}", first_name, last_name)
|
|
}
|
|
// Or (this wasn't previously supported):
|
|
async fn some_route(web::Path((first_name, last_name)): web::Path<(String, String)>) -> String {
|
|
format!("Hello, {} {}", first_name, last_name)
|
|
}
|
|
```
|
|
|
|
* `middleware::NormalizePath` can now also be configured to trim trailing slashes instead of always keeping one.
|
|
It will need `middleware::normalize::TrailingSlash` when being constructed with `NormalizePath::new(...)`,
|
|
or for an easier migration you can replace `wrap(middleware::NormalizePath)` with `wrap(middleware::NormalizePath::new(TrailingSlash::MergeOnly))`.
|
|
|
|
* `HttpServer::maxconn` is renamed to the more expressive `HttpServer::max_connections`.
|
|
|
|
* `HttpServer::maxconnrate` is renamed to the more expressive `HttpServer::max_connection_rate`.
|
|
|
|
|
|
## 2.0.0
|
|
|
|
* `HttpServer::start()` renamed to `HttpServer::run()`. It also possible to
|
|
`.await` on `run` method result, in that case it awaits server exit.
|
|
|
|
* `App::register_data()` renamed to `App::app_data()` and accepts any type `T: 'static`.
|
|
Stored data is available via `HttpRequest::app_data()` method at runtime.
|
|
|
|
* Extractor configuration must be registered with `App::app_data()` instead of `App::data()`
|
|
|
|
* Sync handlers has been removed. `.to_async()` method has been renamed to `.to()`
|
|
replace `fn` with `async fn` to convert sync handler to async
|
|
|
|
* `actix_http_test::TestServer` moved to `actix_web::test` module. To start
|
|
test server use `test::start()` or `test_start_with_config()` methods
|
|
|
|
* `ResponseError` trait has been reafctored. `ResponseError::error_response()` renders
|
|
http response.
|
|
|
|
* Feature `rust-tls` renamed to `rustls`
|
|
|
|
instead of
|
|
|
|
```rust
|
|
actix-web = { version = "2.0.0", features = ["rust-tls"] }
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
actix-web = { version = "2.0.0", features = ["rustls"] }
|
|
```
|
|
|
|
* Feature `ssl` renamed to `openssl`
|
|
|
|
instead of
|
|
|
|
```rust
|
|
actix-web = { version = "2.0.0", features = ["ssl"] }
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
actix-web = { version = "2.0.0", features = ["openssl"] }
|
|
```
|
|
* `Cors` builder now requires that you call `.finish()` to construct the middleware
|
|
|
|
## 1.0.1
|
|
|
|
* Cors middleware has been moved to `actix-cors` crate
|
|
|
|
instead of
|
|
|
|
```rust
|
|
use actix_web::middleware::cors::Cors;
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
use actix_cors::Cors;
|
|
```
|
|
|
|
* Identity middleware has been moved to `actix-identity` crate
|
|
|
|
instead of
|
|
|
|
```rust
|
|
use actix_web::middleware::identity::{Identity, CookieIdentityPolicy, IdentityService};
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
use actix_identity::{Identity, CookieIdentityPolicy, IdentityService};
|
|
```
|
|
|
|
|
|
## 1.0.0
|
|
|
|
* Extractor configuration. In version 1.0 this is handled with the new `Data` mechanism for both setting and retrieving the configuration
|
|
|
|
instead of
|
|
|
|
```rust
|
|
|
|
#[derive(Default)]
|
|
struct ExtractorConfig {
|
|
config: String,
|
|
}
|
|
|
|
impl FromRequest for YourExtractor {
|
|
type Config = ExtractorConfig;
|
|
type Result = Result<YourExtractor, Error>;
|
|
|
|
fn from_request(req: &HttpRequest, cfg: &Self::Config) -> Self::Result {
|
|
println!("use the config: {:?}", cfg.config);
|
|
...
|
|
}
|
|
}
|
|
|
|
App::new().resource("/route_with_config", |r| {
|
|
r.post().with_config(handler_fn, |cfg| {
|
|
cfg.0.config = "test".to_string();
|
|
})
|
|
})
|
|
|
|
```
|
|
|
|
use the HttpRequest to get the configuration like any other `Data` with `req.app_data::<C>()` and set it with the `data()` method on the `resource`
|
|
|
|
```rust
|
|
#[derive(Default)]
|
|
struct ExtractorConfig {
|
|
config: String,
|
|
}
|
|
|
|
impl FromRequest for YourExtractor {
|
|
type Error = Error;
|
|
type Future = Result<Self, Self::Error>;
|
|
type Config = ExtractorConfig;
|
|
|
|
fn from_request(req: &HttpRequest, payload: &mut Payload) -> Self::Future {
|
|
let cfg = req.app_data::<ExtractorConfig>();
|
|
println!("config data?: {:?}", cfg.unwrap().role);
|
|
...
|
|
}
|
|
}
|
|
|
|
App::new().service(
|
|
resource("/route_with_config")
|
|
.data(ExtractorConfig {
|
|
config: "test".to_string(),
|
|
})
|
|
.route(post().to(handler_fn)),
|
|
)
|
|
```
|
|
|
|
* Resource registration. 1.0 version uses generalized resource
|
|
registration via `.service()` method.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
App.new().resource("/welcome", |r| r.f(welcome))
|
|
```
|
|
|
|
use App's or Scope's `.service()` method. `.service()` method accepts
|
|
object that implements `HttpServiceFactory` trait. By default
|
|
actix-web provides `Resource` and `Scope` services.
|
|
|
|
```rust
|
|
App.new().service(
|
|
web::resource("/welcome")
|
|
.route(web::get().to(welcome))
|
|
.route(web::post().to(post_handler))
|
|
```
|
|
|
|
* Scope registration.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
let app = App::new().scope("/{project_id}", |scope| {
|
|
scope
|
|
.resource("/path1", |r| r.f(|_| HttpResponse::Ok()))
|
|
.resource("/path2", |r| r.f(|_| HttpResponse::Ok()))
|
|
.resource("/path3", |r| r.f(|_| HttpResponse::MethodNotAllowed()))
|
|
});
|
|
```
|
|
|
|
use `.service()` for registration and `web::scope()` as scope object factory.
|
|
|
|
```rust
|
|
let app = App::new().service(
|
|
web::scope("/{project_id}")
|
|
.service(web::resource("/path1").to(|| HttpResponse::Ok()))
|
|
.service(web::resource("/path2").to(|| HttpResponse::Ok()))
|
|
.service(web::resource("/path3").to(|| HttpResponse::MethodNotAllowed()))
|
|
);
|
|
```
|
|
|
|
* `.with()`, `.with_async()` registration methods have been renamed to `.to()` and `.to_async()`.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
App.new().resource("/welcome", |r| r.with(welcome))
|
|
```
|
|
|
|
use `.to()` or `.to_async()` methods
|
|
|
|
```rust
|
|
App.new().service(web::resource("/welcome").to(welcome))
|
|
```
|
|
|
|
* Passing arguments to handler with extractors, multiple arguments are allowed
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn welcome((body, req): (Bytes, HttpRequest)) -> ... {
|
|
...
|
|
}
|
|
```
|
|
|
|
use multiple arguments
|
|
|
|
```rust
|
|
fn welcome(body: Bytes, req: HttpRequest) -> ... {
|
|
...
|
|
}
|
|
```
|
|
|
|
* `.f()`, `.a()` and `.h()` handler registration methods have been removed.
|
|
Use `.to()` for handlers and `.to_async()` for async handlers. Handler function
|
|
must use extractors.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
App.new().resource("/welcome", |r| r.f(welcome))
|
|
```
|
|
|
|
use App's `to()` or `to_async()` methods
|
|
|
|
```rust
|
|
App.new().service(web::resource("/welcome").to(welcome))
|
|
```
|
|
|
|
* `HttpRequest` does not provide access to request's payload stream.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn index(req: &HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
|
|
req
|
|
.payload()
|
|
.from_err()
|
|
.fold((), |_, chunk| {
|
|
...
|
|
})
|
|
.map(|_| HttpResponse::Ok().finish())
|
|
.responder()
|
|
}
|
|
```
|
|
|
|
use `Payload` extractor
|
|
|
|
```rust
|
|
fn index(stream: web::Payload) -> impl Future<Item=HttpResponse, Error=Error> {
|
|
stream
|
|
.from_err()
|
|
.fold((), |_, chunk| {
|
|
...
|
|
})
|
|
.map(|_| HttpResponse::Ok().finish())
|
|
}
|
|
```
|
|
|
|
* `State` is now `Data`. You register Data during the App initialization process
|
|
and then access it from handlers either using a Data extractor or using
|
|
HttpRequest's api.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
App.with_state(T)
|
|
```
|
|
|
|
use App's `data` method
|
|
|
|
```rust
|
|
App.new()
|
|
.data(T)
|
|
```
|
|
|
|
and either use the Data extractor within your handler
|
|
|
|
```rust
|
|
use actix_web::web::Data;
|
|
|
|
fn endpoint_handler(Data<T>)){
|
|
...
|
|
}
|
|
```
|
|
|
|
.. or access your Data element from the HttpRequest
|
|
|
|
```rust
|
|
fn endpoint_handler(req: HttpRequest) {
|
|
let data: Option<Data<T>> = req.app_data::<T>();
|
|
}
|
|
```
|
|
|
|
|
|
* AsyncResponder is removed, use `.to_async()` registration method and `impl Future<>` as result type.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
use actix_web::AsyncResponder;
|
|
|
|
fn endpoint_handler(...) -> impl Future<Item=HttpResponse, Error=Error>{
|
|
...
|
|
.responder()
|
|
}
|
|
```
|
|
|
|
.. simply omit AsyncResponder and the corresponding responder() finish method
|
|
|
|
|
|
* Middleware
|
|
|
|
instead of
|
|
|
|
```rust
|
|
let app = App::new()
|
|
.middleware(middleware::Logger::default())
|
|
```
|
|
|
|
use `.wrap()` method
|
|
|
|
```rust
|
|
let app = App::new()
|
|
.wrap(middleware::Logger::default())
|
|
.route("/index.html", web::get().to(index));
|
|
```
|
|
|
|
* `HttpRequest::body()`, `HttpRequest::urlencoded()`, `HttpRequest::json()`, `HttpRequest::multipart()`
|
|
method have been removed. Use `Bytes`, `String`, `Form`, `Json`, `Multipart` extractors instead.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn index(req: &HttpRequest) -> Responder {
|
|
req.body()
|
|
.and_then(|body| {
|
|
...
|
|
})
|
|
}
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
fn index(body: Bytes) -> Responder {
|
|
...
|
|
}
|
|
```
|
|
|
|
* `actix_web::server` module has been removed. To start http server use `actix_web::HttpServer` type
|
|
|
|
* StaticFiles and NamedFile have been moved to a separate crate.
|
|
|
|
instead of `use actix_web::fs::StaticFile`
|
|
|
|
use `use actix_files::Files`
|
|
|
|
instead of `use actix_web::fs::Namedfile`
|
|
|
|
use `use actix_files::NamedFile`
|
|
|
|
* Multipart has been moved to a separate crate.
|
|
|
|
instead of `use actix_web::multipart::Multipart`
|
|
|
|
use `use actix_multipart::Multipart`
|
|
|
|
* Response compression is not enabled by default.
|
|
To enable, use `Compress` middleware, `App::new().wrap(Compress::default())`.
|
|
|
|
* Session middleware moved to actix-session crate
|
|
|
|
* Actors support have been moved to `actix-web-actors` crate
|
|
|
|
* Custom Error
|
|
|
|
Instead of error_response method alone, ResponseError now provides two methods: error_response and render_response respectively. Where, error_response creates the error response and render_response returns the error response to the caller.
|
|
|
|
Simplest migration from 0.7 to 1.0 shall include below method to the custom implementation of ResponseError:
|
|
|
|
```rust
|
|
fn render_response(&self) -> HttpResponse {
|
|
self.error_response()
|
|
}
|
|
```
|
|
|
|
## 0.7.15
|
|
|
|
* The `' '` character is not percent decoded anymore before matching routes. If you need to use it in
|
|
your routes, you should use `%20`.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn main() {
|
|
let app = App::new().resource("/my index", |r| {
|
|
r.method(http::Method::GET)
|
|
.with(index);
|
|
});
|
|
}
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
fn main() {
|
|
let app = App::new().resource("/my%20index", |r| {
|
|
r.method(http::Method::GET)
|
|
.with(index);
|
|
});
|
|
}
|
|
```
|
|
|
|
* If you used `AsyncResult::async` you need to replace it with `AsyncResult::future`
|
|
|
|
|
|
## 0.7.4
|
|
|
|
* `Route::with_config()`/`Route::with_async_config()` always passes configuration objects as tuple
|
|
even for handler with one parameter.
|
|
|
|
|
|
## 0.7
|
|
|
|
* `HttpRequest` does not implement `Stream` anymore. If you need to read request payload
|
|
use `HttpMessage::payload()` method.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn index(req: HttpRequest) -> impl Responder {
|
|
req
|
|
.from_err()
|
|
.fold(...)
|
|
....
|
|
}
|
|
```
|
|
|
|
use `.payload()`
|
|
|
|
```rust
|
|
fn index(req: HttpRequest) -> impl Responder {
|
|
req
|
|
.payload() // <- get request payload stream
|
|
.from_err()
|
|
.fold(...)
|
|
....
|
|
}
|
|
```
|
|
|
|
* [Middleware](https://actix.rs/actix-web/actix_web/middleware/trait.Middleware.html)
|
|
trait uses `&HttpRequest` instead of `&mut HttpRequest`.
|
|
|
|
* Removed `Route::with2()` and `Route::with3()` use tuple of extractors instead.
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn index(query: Query<..>, info: Json<MyStruct) -> impl Responder {}
|
|
```
|
|
|
|
use tuple of extractors and use `.with()` for registration:
|
|
|
|
```rust
|
|
fn index((query, json): (Query<..>, Json<MyStruct)) -> impl Responder {}
|
|
```
|
|
|
|
* `Handler::handle()` uses `&self` instead of `&mut self`
|
|
|
|
* `Handler::handle()` accepts reference to `HttpRequest<_>` instead of value
|
|
|
|
* Removed deprecated `HttpServer::threads()`, use
|
|
[HttpServer::workers()](https://actix.rs/actix-web/actix_web/server/struct.HttpServer.html#method.workers) instead.
|
|
|
|
* Renamed `client::ClientConnectorError::Connector` to
|
|
`client::ClientConnectorError::Resolver`
|
|
|
|
* `Route::with()` does not return `ExtractorConfig`, to configure
|
|
extractor use `Route::with_config()`
|
|
|
|
instead of
|
|
|
|
```rust
|
|
fn main() {
|
|
let app = App::new().resource("/index.html", |r| {
|
|
r.method(http::Method::GET)
|
|
.with(index)
|
|
.limit(4096); // <- limit size of the payload
|
|
});
|
|
}
|
|
```
|
|
|
|
use
|
|
|
|
```rust
|
|
|
|
fn main() {
|
|
let app = App::new().resource("/index.html", |r| {
|
|
r.method(http::Method::GET)
|
|
.with_config(index, |cfg| { // <- register handler
|
|
cfg.limit(4096); // <- limit size of the payload
|
|
})
|
|
});
|
|
}
|
|
```
|
|
|
|
* `Route::with_async()` does not return `ExtractorConfig`, to configure
|
|
extractor use `Route::with_async_config()`
|
|
|
|
|
|
## 0.6
|
|
|
|
* `Path<T>` extractor return `ErrorNotFound` on failure instead of `ErrorBadRequest`
|
|
|
|
* `ws::Message::Close` now includes optional close reason.
|
|
`ws::CloseCode::Status` and `ws::CloseCode::Empty` have been removed.
|
|
|
|
* `HttpServer::threads()` renamed to `HttpServer::workers()`.
|
|
|
|
* `HttpServer::start_ssl()` and `HttpServer::start_tls()` deprecated.
|
|
Use `HttpServer::bind_ssl()` and `HttpServer::bind_tls()` instead.
|
|
|
|
* `HttpRequest::extensions()` returns read only reference to the request's Extension
|
|
`HttpRequest::extensions_mut()` returns mutable reference.
|
|
|
|
* Instead of
|
|
|

* `FromRequest::from_request()` accepts mutable reference to a request
|
|
|
|
* `FromRequest::Result` has to implement `Into<Reply<Self>>`
|
|
|
|
* [`Responder::respond_to()`](
|
|
https://actix.rs/actix-web/actix_web/trait.Responder.html#tymethod.respond_to)
|
|
is generic over `S`
|
|
|
|
* Use `Query` extractor instead of HttpRequest::query()`.
|
|
|
|
```rust
|
|
fn index(q: Query<HashMap<String, String>>) -> Result<..> {
|
|
...
|
|
}
|
|
```
|
|
|
|
or
|
|
|
|
```rust
|
|
let q = Query::<HashMap<String, String>>::extract(req);
|
|
```
|
|
|
|
* Websocket operations are implemented as `WsWriter` trait.
|
|
you need to use `use actix_web::ws::WsWriter`
