pub struct Form<T>(pub T);
Expand description
URL encoded extractor and response.
§As extractor
If used as an extractor Form
will deserialize the query parameters for GET
and HEAD
requests and application/x-www-form-urlencoded
encoded request bodies for other methods. It
supports any type that implements serde::Deserialize
.
⚠️ Since parsing form data might require consuming the request body, the Form
extractor must be
last if there are multiple extractors in a handler. See “the order of
extractors”
use axum::Form;
use serde::Deserialize;
#[derive(Deserialize)]
struct SignUp {
username: String,
password: String,
}
async fn accept_form(Form(sign_up): Form<SignUp>) {
// ...
}
Note that Content-Type: multipart/form-data
requests are not supported. Use Multipart
instead.
§As response
use axum::Form;
use serde::Serialize;
#[derive(Serialize)]
struct Payload {
value: String,
}
async fn handler() -> Form<Payload> {
Form(Payload { value: "foo".to_owned() })
}

If the extractor fails it’ll use this “rejection” type. A rejection is
a kind of error that can be converted into a response.
