Getting strange 405 when a route is associated with multiple methods

[axos88]

Expected Behavior

It should accept POST, DELETE and PUT and route the request correctly

Current Behavior

Returns 405, and the accept header contains the actual method used (but if invoked with POST or PUT, it's just the GET?)

Steps to Reproduce (for bugs)

async fn hello() -> impl Responder {
    info!("Sending a String.");
    "Hallo Welt"
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(move || {
        App::new()
            .service(web::resource("/hello").route(web::post().method(http::Method::DELETE).method(http::Method::PUT).to(hello)))
            .default_service(
                web::route().to(async || HttpResponse::NotFound().finish()),
            )
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

$ curl -i localhost:8080/hello

Your Environment

• Actix Web Version: 4.3.1

That isn't how guards work. Please take a look at the guard docs, it seems that you probably want the Any guard.

If you are okay to use macro routing, it's slightly easier to achieve: https://docs.rs/actix-web/latest/actix_web/attr.route.html

#[route("/test", method = "GET", method = "HEAD", method = "CUSTOM")]
async fn example() -> HttpResponse {
    HttpResponse::Ok().finish()
}
