Struct actix_web::Query

pub struct Query<T>(_);

Extract typed information from from the request's query.

Example

#[macro_use] extern crate serde_derive;
use actix_web::{App, Query, http};


#[derive(Debug, Deserialize)]
pub enum ResponseType {
   Token,
   Code
}

#[derive(Deserialize)]
pub struct AuthRequest {
   id: u64,
   response_type: ResponseType,
}

// use `with` extractor for query info
// this handler get called only if request's query contains `username` field
// The correct request for this handler would be `/index.html?id=64&response_type=Code"`
fn index(info: Query<AuthRequest>) -> String {
    format!("Authorization request for client with id={} and type={:?}!", info.id, info.response_type)
}

fn main() {
    let app = App::new().resource(
       "/index.html",
       |r| r.method(http::Method::GET).with(index)); // <- use `with` extractor
}
