Raw Blame History

Unreleased

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:

// 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::default()).
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

actix-web = { version = "2.0.0", features = ["rust-tls"] }

use

actix-web = { version = "2.0.0", features = ["rustls"] }

Feature ssl renamed to openssl

instead of

actix-web = { version = "2.0.0", features = ["ssl"] }

use

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

use actix_web::middleware::cors::Cors;

use

use actix_cors::Cors;

Identity middleware has been moved to actix-identity crate

instead of

use actix_web::middleware::identity::{Identity, CookieIdentityPolicy, IdentityService};

use

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


#[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

#[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
```
  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.
```
  App.new().service(
      web::resource("/welcome")
          .route(web::get().to(welcome))
          .route(web::post().to(post_handler))
```

Scope registration.

instead of

    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.

    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

  App.new().resource("/welcome", |r| r.with(welcome))

use .to() or .to_async() methods

  App.new().service(web::resource("/welcome").to(welcome))

Passing arguments to handler with extractors, multiple arguments are allowed

instead of

fn welcome((body, req): (Bytes, HttpRequest)) -> ... {
  ...
}

use multiple arguments

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
```
  App.new().resource("/welcome", |r| r.f(welcome))
```
use App's to() or to_async() methods
```
  App.new().service(web::resource("/welcome").to(welcome))
```

HttpRequest does not provide access to request's payload stream.

instead of

fn index(req: &HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
  req
     .payload()
     .from_err()
     .fold((), |_, chunk| {
          ...
      })
     .map(|_| HttpResponse::Ok().finish())
     .responder()
}

use Payload extractor

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
```
  App.with_state(T)
```
use App's data method
```
  App.new()
     .data(T)
```
and either use the Data extractor within your handler
```
  use actix_web::web::Data;

  fn endpoint_handler(Data<T>)){
    ...
  }
```
.. or access your Data element from the HttpRequest
```
  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
```
  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

    let app = App::new()
         .middleware(middleware::Logger::default())

use .wrap() method

    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

fn index(req: &HttpRequest) -> Responder {
   req.body()
     .and_then(|body| {
        ...
     })
}

use

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:
```
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

fn main() {
     let app = App::new().resource("/my index", |r| {
         r.method(http::Method::GET)
                .with(index);
     });
}

use

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

fn index(req: HttpRequest) -> impl Responder {
     req
        .from_err()
        .fold(...)
        ....
}

use .payload()

fn index(req: HttpRequest) -> impl Responder {
     req
        .payload()  // <- get request payload stream
        .from_err()
        .fold(...)
        ....
}

Middleware trait uses &HttpRequest instead of &mut HttpRequest.

Removed Route::with2() and Route::with3() use tuple of extractors instead.

instead of

fn index(query: Query<..>, info: Json<MyStruct) -> impl Responder {}

use tuple of extractors and use .with() for registration:

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() instead.
Renamed client::ClientConnectorError::Connector to client::ClientConnectorError::Resolver

Route::with() does not return ExtractorConfig, to configure extractor use Route::with_config()

instead of

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


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

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() is generic over S

Use Query extractor instead of HttpRequest::query()`.

fn index(q: Query<HashMap<String, String>>) -> Result<..> {
    ...
}

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
actix_web::header moved to actix_web::http::header
NormalizePath moved to actix_web::http module
