//! Cross-Origin Resource Sharing (CORS) controls for Actix Web.
|
|
//!
|
|
//! This middleware can be applied to both applications and resources. Once built,
|
|
//! [`CorsFactory`] can be used as a parameter for actix-web `App::wrap()`,
|
|
//! `Scope::wrap()`, or `Resource::wrap()` methods.
|
|
//!
|
|
//! This CORS middleware automatically handles `OPTIONS` preflight requests.
|
|
//!
|
|
//! # Example
|
|
//!
|
|
//! In this example a custom CORS middleware is registered for the "/index.html" endpoint.
|
|
//!
|
|
//! ```rust,no_run
|
|
//! use actix_cors::Cors;
|
|
//! use actix_web::{get, http, web, App, HttpRequest, HttpResponse, HttpServer};
|
|
//!
|
|
//! #[get("/index.html")]
|
|
//! async fn index(req: HttpRequest) -> &'static str {
|
|
//! "<p>Hello World!</p>"
|
|
//! }
|
|
//!
|
|
//! #[actix_web::main]
|
|
//! async fn main() -> std::io::Result<()> {
|
|
//! HttpServer::new(|| {
|
|
//! let cors = Cors::new()
|
|
//! .allowed_origin("https://www.rust-lang.org/")
|
|
//! .allowed_origin_fn(|req| {
|
|
//! req.headers
|
|
//! .get(http::header::ORIGIN)
|
|
//! .map(http::HeaderValue::as_bytes)
|
|
//! .filter(|b| b.ends_with(b".rust-lang.org"))
|
|
//! .is_some()
|
|
//! })
|
|
//! .allowed_methods(vec!["GET", "POST"])
|
|
//! .allowed_headers(vec![http::header::AUTHORIZATION, http::header::ACCEPT])
|
|
//! .allowed_header(http::header::CONTENT_TYPE)
|
|
//! .max_age(3600)
|
|
//! .finish();
|
|
//!
|
|
//! App::new()
|
|
//! .wrap(cors)
|
|
//! .service(index)
|
|
//! })
|
|
//! .bind(("127.0.0.1", 8080))?
|
|
//! .run()
|
|
//! .await;
|
|
//!
|
|
//! Ok(())
|
|
//! }
|
|
//! ```
