# Paramètres de requête et validations de chaînes de caractères

**FastAPI** vous permet de déclarer des informations et des validateurs additionnels pour vos paramètres de requêtes.

Commençons avec cette application pour exemple :

{* ../../docs_src/query_params_str_validations/tutorial001.py hl[9] *}

     *
     * @param <T>
     *            The return type of the method
     * @param method
     *            The method. Cannot be {@literal null}
     * @param args
     *            The arguments used for the method call
     * @return The result of dispatching the {@code static} method using the parameters {@code args}
     * @throws IllegalAccessRuntimeException

# Pfadoperation-Konfiguration { #path-operation-configuration }

Es gibt mehrere Parameter, die Sie Ihrem *Pfadoperation-Dekorator* übergeben können, um ihn zu konfigurieren.

/// warning | Achtung

Beachten Sie, dass diese Parameter direkt dem *Pfadoperation-Dekorator* übergeben werden, nicht der *Pfadoperation-Funktion*.
