[][src]Struct actix_web::middleware::cors::Cors

pub struct Cors { /* fields omitted */ }

Middleware for Cross-origin resource sharing support

The Cors struct contains the settings for CORS requests to be validated and for responses to be generated.

Methods

impl Cors
[src]

Build a new CORS middleware instance

Create CorsBuilder for a specified application.

use actix_web::middleware::cors::Cors;
use actix_web::{http, App, HttpResponse};

fn main() {
    let app = App::new().configure(
        |app| {
            Cors::for_app(app)   // <- Construct CORS builder
            .allowed_origin("https://www.rust-lang.org/")
            .resource("/resource", |r| {       // register resource
                 r.method(http::Method::GET).f(|_| HttpResponse::Ok());
            })
            .register()
        }, // construct CORS and return application instance
    );
}

This method register cors middleware with resource and adds route for OPTIONS preflight requests.

It is possible to register Cors middleware with Resource::middleware() method, but in that case Cors middleware wont be able to handle OPTIONS requests.
