pub struct AppendHeaders<I>(pub I);Expand description
Append headers to a response.
Returning something like [("content-type", "foo=bar")] from a handler will override any
existing content-type headers. If instead you want to append headers, use AppendHeaders:
use axum::{
response::{AppendHeaders, IntoResponse},
http::header::SET_COOKIE,
};
async fn handler() -> impl IntoResponse {
// something that sets the `set-cookie` header
let set_some_cookies = /* ... */
(
set_some_cookies,
// append two `set-cookie` headers to the response
// without overriding the ones added by `set_some_cookies`
AppendHeaders([
(SET_COOKIE, "foo=bar"),
(SET_COOKIE, "baz=qux"),
])
)
