Struct DefaultHeaders 

pub struct DefaultHeaders { /* private fields */ }

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::default()
        .middleware(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() }))
        );
}

Implementations

impl DefaultHeaders

pub fn new() -> DefaultHeaders

Construct DefaultHeaders middleware.

pub fn header<K, V>(self, key: K, value: V) -> Self

where HeaderName: TryFrom<K>, <HeaderName as TryFrom<K>>::Error: Into<HttpError>, HeaderValue: TryFrom<V>, <HeaderValue as TryFrom<V>>::Error: Into<HttpError>,

Set a header.

pub fn content_type(self) -> Self

Set CONTENT-TYPE header if response does not contain this header.

The header is set to application/octet-stream.

impl Debug for DefaultHeaders

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DefaultHeaders

fn default() -> Self

impl<S, St> Middleware<S, St> for DefaultHeaders

type Service = DefaultHeadersMiddleware<S>

Service created by this middleware.

fn create(&self, _: &St, service: S) -> Self::Service
