Struct actix_web::Form

[+] Show declaration

pub struct Form<T>(pub T);

[−] Expand description

Extract typed information from the request's body.

To extract typed information from request's body, the type T must implement the Deserialize trait from serde.

FormConfig allows to configure extraction process.

Example

#[macro_use] extern crate serde_derive;
use actix_web::{App, Form, Result};

#[derive(Deserialize)]
struct FormData {
    username: String,
}

/// extract form data using serde
/// this handler get called only if content type is *x-www-form-urlencoded*
/// and content of the request could be deserialized to a `FormData` struct
fn index(form: Form<FormData>) -> Result<String> {
    Ok(format!("Welcome {}!", form.username))
}
