|
||
//!
|
||
//! This middleware can be applied to both applications and resources. Once built, a
|
||
//! [`Cors`] builder can be used as an argument for Actix Web's `App::wrap()`,
|
||
//! `Scope::wrap()`, or `Resource::wrap()` methods.
|
||
//!
|
||
//! This CORS middleware automatically handles `OPTIONS` preflight requests.
|
||
//!
|
||
//! # Example
|
||
//! ```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::default()
|
||
//! .allowed_origin("https://www.rust-lang.org/")
|
||
//! .allowed_origin_fn(|origin, _req_head| {
|
||
//! origin.as_bytes().ends_with(b".rust-lang.org")
|
||
//! })
|
||
//! .allowed_methods(vec!["GET", "POST"])
|
||
//! .allowed_headers(vec![http::header::AUTHORIZATION, http::header::ACCEPT])
|
||
//! .allowed_header(http::header::CONTENT_TYPE)
|
||
//! .max_age(3600);
|
||
//!
|
||
//! App::new()
|
||
//! .wrap(cors)
|
||
//! .service(index)
|
||
//! })
|
||
//! .bind(("127.0.0.1", 8080))?
|
||
//! .run()
|
||
//! .await;
|
||
//!
|
||
//! Ok(())
|
||
//! }
