如何配置actix-web以接受来自任何来源的CORS请求？

[dependencies]
actix-web = "3.3"
actix-rt = "2.4"

use actix_web::{web, App, HttpRequest, HttpServer, HttpResponse, Result};
use actix_cors::Cors;

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        let cors = Cors::default()
            .allow_any_origin()
            .allow_methods(vec!["GET", "POST"])
            .allow_headers(vec!["Content-Type"])
            .max_age(3600);
            
        App::new()
            .wrap(cors)
            .service(web::resource("/").route(web::get().to(index)))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

async fn index(req: HttpRequest) -> Result<HttpResponse> {
    Ok(HttpResponse::Ok().body("Hello, CORS!"))
}
