Query extractor configuration.
Examples
use actix_web::{error, get, web, App, FromRequest, HttpResponse};
use serde::Deserialize;
#[derive(Deserialize)]
struct Info {
username: String,
}
/// deserialize `Info` from request's querystring
#[get("/")]
async fn index(info: web::Query<Info>) -> String {
format!("Welcome {}!", info.username)
}
// custom `Query` extractor configuration
let query_cfg = web::QueryConfig::default()
// use custom error handler
.error_handler(|err, req| {
