Crate actix_cors

Expand description

Cross-Origin Resource Sharing (CORS) controls for Actix Web.

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.

§Crate Features

draft-private-network-access: ⚠️ Unstable. Adds opt-in support for the Private Network Access spec extensions. This feature is unstable since it will follow breaking changes in the draft spec until it is finalized.

§Example

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(())
}
