## 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
`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
* `actix_web::header` moved to `actix_web::http::header`
* `NormalizePath` moved to `actix_web::http` module
* `HttpServer` moved to `actix_web::server`, added new `actix_web::server::new()` function,
shortcut for `actix_web::server::HttpServer::new()`
* `DefaultHeaders` middleware does not use separate builder, all builder methods moved to type itself
* `StaticFiles::new()`'s show_index parameter removed, use `show_files_listing()` method instead.
* `CookieSessionBackendBuilder` removed, all methods moved to `CookieSessionBackend` type
* `actix_web::httpcodes` module is deprecated, `HttpResponse::Ok()`, `HttpResponse::Found()` and other `HttpResponse::XXX()`
functions should be used instead
* `ClientRequestBuilder::body()` returns `Result<_, actix_web::Error>`
instead of `Result<_, http::Error>`
* `Application` renamed to a `App`
* `actix_web::Reply`, `actix_web::Resource` moved to `actix_web::dev`

//! A filter for cross-site request forgery (CSRF).
//!
//! This middleware is stateless and [based on request
//! headers](https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)_Prevention_Cheat_Sheet#Verifying_Same_Origin_with_Standard_Headers).
//!
//! By default requests are allowed only if one of these is true:
//!
//! * The request method is safe (`GET`, `HEAD`, `OPTIONS`). It is the
//! applications responsibility to ensure these methods cannot be used to
//! execute unwanted actions. Note that upgrade requests for websockets are
//! also considered safe.
//! * The `Origin` header (added automatically by the browser) matches one
//! of the allowed origins.
//! * There is no `Origin` header but the `Referer` header matches one of
//! the allowed origins.
//!
//! Use [`CsrfFilter::allow_xhr()`](struct.CsrfFilter.html#method.allow_xhr)
//! if you want to allow requests with unprotected methods via
//! [CORS](../cors/struct.Cors.html).
//!
//! # Example
//!
//! ```
//! # extern crate actix_web;
//! use actix_web::middleware::csrf;
//! use actix_web::{http, App, HttpRequest, HttpResponse};
//!
//! fn handle_post(_: &HttpRequest) -> &'static str {
//! "This action should only be triggered with requests from the same site"
//! }
//!
//! fn main() {
//! let app = App::new()
//! .middleware(
//! csrf::CsrfFilter::new().allowed_origin("https://www.example.com"),
//! )
//! .resource("/", |r| {
//! r.method(http::Method::GET).f(|_| HttpResponse::Ok());
//! r.method(http::Method::POST).f(handle_post);
//! })
//! .finish();
//! }
//! ```
//!
//! In this example the entire application is protected from CSRF.

//! User sessions.
//!
//! Actix provides a general solution for session management. The
//! [**SessionStorage**](struct.SessionStorage.html)
//! middleware can be used with different backend types to store session
//! data in different backends.
//!
//! By default, only cookie session backend is implemented. Other
//! backend implementations can be added.
//!
//! [**CookieSessionBackend**](struct.CookieSessionBackend.html)
//! uses cookies as session storage. `CookieSessionBackend` creates sessions
//! which are limited to storing fewer than 4000 bytes of data, as the payload
//! must fit into a single cookie. An internal server error is generated if a
//! session contains more than 4000 bytes.
//!
//! A cookie may have a security policy of *signed* or *private*. Each has
//! a respective `CookieSessionBackend` constructor.
//!
//! A *signed* cookie may be viewed but not modified by the client. A *private*
//! cookie may neither be viewed nor modified by the client.
//!
//! The constructors take a key as an argument. This is the private key
//! for cookie session - when this value is changed, all session data is lost.
//!
//! In general, you create a `SessionStorage` middleware and initialize it
//! with specific backend implementation, such as a `CookieSessionBackend`.
//! To access session data,
//! [*HttpRequest::session()*](trait.RequestSession.html#tymethod.session)
//! must be used. This method returns a
//! [*Session*](struct.Session.html) object, which allows us to get or set
//! session data.
//!
//! ```rust
//! # extern crate actix_web;
//! use actix_web::{actix, server, App, HttpRequest, Result};
//! use actix_web::middleware::session::{RequestSession, SessionStorage, CookieSessionBackend};
//!
//! fn index(req: HttpRequest) -> Result<&'static str> {
//! // access session data
//! if let Some(count) = req.session().get::<i32>("counter")? {
//! println!("SESSION value: {}", count);
//! req.session().set("counter", count+1)?;
//! } else {

/// cookie). An Internal Server Error is generated if the session contains more
/// than 4000 bytes.
///
/// A cookie may have a security policy of *signed* or *private*. Each has a
/// respective `CookieSessionBackend` constructor.
///
/// A *signed* cookie is stored on the client as plaintext alongside
/// a signature such that the cookie may be viewed but not modified by the
/// client.
///
/// A *private* cookie is stored on the client as encrypted text
/// such that it may neither be viewed nor modified by the client.
///
/// The constructors take a key as an argument.
/// This is the private key for cookie session - when this value is changed,
/// all session data is lost. The constructors will panic if the key is less
/// than 32 bytes in length.
///
/// The backend relies on `cookie` crate to create and read cookies.
/// By default all cookies are percent encoded, but certain symbols may
/// cause troubles when reading cookie, if they are not properly percent encoded.

///
/// ```rust
/// # extern crate actix_web;
