## 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 has been move to separate create.
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 move to separate create.
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() .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); });
}
```
use
```rust
fn main() {
let app = App::new().resource("/index.html", |r| {
r.method(http::Method::GET)
.with_config(index, |cfg| { cfg.limit(4096); })
});
}
```
* `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
`use actix_web::middleware::{
CookieSessionBackend, CookieSessionError, RequestSession,
Session, SessionBackend, SessionImpl, SessionStorage};`
use `actix_web::middleware::session`
`use actix_web::middleware::session{CookieSessionBackend, CookieSessionError,
RequestSession, Session, SessionBackend, SessionImpl, SessionStorage};`
* `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`
## 0.5
* `HttpResponseBuilder::body()`, `.finish()`, `.json()`
methods return `HttpResponse` instead of `Result<HttpResponse>`
* `actix_web::Method`, `actix_web::StatusCode`, `actix_web::Version`
moved to `actix_web::http` module
