Struct ntex::web::middleware::DefaultHeaders

pub struct DefaultHeaders { /* fields omitted */ }

Middleware for setting default response headers.

This middleware does not set header if response headers already contains it.

use ntex::http;
use ntex::web::{self, middleware, App, HttpResponse};

fn main() {
    let app = App::new()
        .wrap(middleware::DefaultHeaders::new().header("X-Version", "0.2"))
        .service(
            web::resource("/test")
                .route(web::get().to(|| async { HttpResponse::Ok() }))
                .route(web::method(http::Method::HEAD).to(|| async { HttpResponse::MethodNotAllowed() }))
        );
}
