Example

use actix_web::{error, web, App, FromRequest, HttpResponse};

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

/// deserialize `Info` from request's querystring
fn index(info: web::Query<Info>) -> String {
    format!("Welcome {}!", info.username)
}

fn main() {
    let app = App::new().service(
        web::resource("/index.html").data(
            // change query extractor configuration
            web::Query::<Info>::configure(|cfg| {
                cfg.error_handler(|err, req| {  // <- create custom error response
                    error::InternalError::from_response(
                        err, HttpResponse::Conflict().finish()).into()
                })
