    err_handler: Option<Arc<dyn Fn(QueryPayloadError, &HttpRequest) -> Error + Send + Sync>>,
}

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

App::new()
    .app_data(query_cfg)
    .service(index);
