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| {
error::InternalError::from_response(err, HttpResponse::Conflict().into()).into()
});
App::new()
