Struct actix_web::middleware::DefaultHeaders
source · pub struct DefaultHeaders { /* private fields */ }
Expand description
Middleware for setting default response headers.
Headers with the same key that are already set in a response will not be overwritten.
Examples
use actix_web::{web, http, middleware, App, HttpResponse};
let app = App::new()
.wrap(middleware::DefaultHeaders::new().add(("X-Version", "0.2")))
.service(
web::resource("/test")
.route(web::get().to(|| HttpResponse::Ok()))
.route(web::method(http::Method::HEAD).to(|| HttpResponse::MethodNotAllowed()))
);
Implementations§
source§impl DefaultHeaders
impl DefaultHeaders
sourcepub fn new() -> DefaultHeaders
pub fn new() -> DefaultHeaders
Constructs an empty DefaultHeaders
middleware.
sourcepub fn add(self, header: impl TryIntoHeaderPair) -> Self
pub fn add(self, header: impl TryIntoHeaderPair) -> Self
sourcepub fn add_content_type(self) -> Self
pub fn add_content_type(self) -> Self
Adds a default Content-Type header if response does not contain one.
Default is application/octet-stream
.
