Struct actix_web::CustomizeResponder

source ·
pub struct CustomizeResponder<R> { /* private fields */ }
Expand description

Allows overriding status code and headers (including cookies) for a Responder.

Created by calling the customize method on a Responder type.

Implementations§

source§

impl<R: Responder> CustomizeResponder<R>

source

pub fn with_status(self, status: StatusCode) -> Self

Override a status code for the Responder’s response.

§Examples
use actix_web::{Responder, http::StatusCode, test::TestRequest};

let responder = "Welcome!".customize().with_status(StatusCode::ACCEPTED);

let request = TestRequest::default().to_http_request();
let response = responder.respond_to(&request);
assert_eq!(response.status(), StatusCode::ACCEPTED);
source

pub fn insert_header(self, header: impl TryIntoHeaderPair) -> Self

Insert (override) header in the final response.

Overrides other headers with the same name. See HeaderMap::insert.

Headers added with this method will be inserted before those added with append_header. As such, header(s) can be overridden with more than one new header by first calling insert_header followed by append_header.

§Examples
use actix_web::{Responder, test::TestRequest};

let responder = "Hello world!"
    .customize()
    .insert_header(("x-version", "1.2.3"));

let request = TestRequest::default().to_http_request();
let response = responder.respond_to(&request);
assert_eq!(response.headers().get("x-version").unwrap(), "1.2.3");
source

pub fn append_header(self, header: impl TryIntoHeaderPair) -> Self

Append header to the final response.

Unlike insert_header, this will not override existing headers. See HeaderMap::append.

Headers added here are appended after additions/overrides from insert_header.

§Examples
use actix_web::{Responder, test::TestRequest};

let responder = "Hello world!"
    .customize()
    .append_header(("x-version", "1.2.3"));

let request = TestRequest::default().to_http_request();
let response = responder.respond_to(&request);
assert_eq!(response.headers().get("x-version").unwrap(), "1.2.3");

Appends a cookie to the final response.

§Errors

Final response will be an error if cookie cannot be converted into a valid header value.
