Struct serde_qs::actix::QsQuery

source ·
pub struct QsQuery<T>(_);
Expand description

Extract typed information from from the request’s query.

Example

use actix_web::{web, App, HttpResponse};
use serde_qs::actix::QsQuery;

#[derive(Deserialize)]
pub struct UsersFilter {
   id: Vec<u64>,
}

// Use `QsQuery` extractor for query information.
// The correct request for this handler would be `/users?id[]=1124&id[]=88"`
async fn filter_users(info: QsQuery<UsersFilter>) -> HttpResponse {
    HttpResponse::Ok().body(
        info.id.iter().map(|i| i.to_string()).collect::<Vec<String>>().join(", ")
    )
}

fn main() {
    let app = App::new().service(
       web::resource("/users")
           .route(web::get().to(filter_users)));
}
