Ainsi, vous pouvez déclarer votre fonction comme suit :

{* ../../docs_src/path_params_numeric_validations/tutorial002.py hl[7] *}

Mais gardez à l'esprit que si vous utilisez `Annotated`, vous n'aurez pas ce problème, cela n'aura pas d'importance car vous n'utilisez pas les valeurs par défaut des paramètres de fonction pour `Query()` ou `Path()`.

En particulier, on voit Uvicorn, Starlette et FastAPI comparés (parmi de nombreux autres outils).

Plus le problème résolu par un outil est simple, mieux seront les performances obtenues. Et la plupart des tests de performance ne prennent pas en compte les fonctionnalités additionnelles fournies par les outils.

La hiérarchie est la suivante :

        #  If you want to change mappings from default mappings, you can specify your original mappings.
        #  But it is possible that unanticipated problems occurs, so be careful!
        #; typeMappingMap = map:{
        #    # AutoMapping for Numeric and Decimal, (1-9,0): INTEGER, (10-18,0): BIGINT, else: NUMERIC
        #    ; NUMERIC = $$AutoMapping$$ ; DECIMAL = $$AutoMapping$$

/// tip | Consejo

Integrar otros proveedores de autenticación/autorización como Google, Facebook, X (Twitter), GitHub, etc. también es posible y relativamente fácil.

El problema más complejo es construir un proveedor de autenticación/autorización como esos, pero **FastAPI** te da las herramientas para hacerlo fácilmente, mientras hace el trabajo pesado por ti.

## Acessando o corpo da requisição em um manipulador de exceção { #accessing-the-request-body-in-an-exception-handler }

/// tip | Dica

Para resolver esse mesmo problema, é provavelmente muito mais fácil usar o `body` em um manipulador personalizado para `RequestValidationError` ([Tratando Erros](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}).

Es gibt mehrere Flask REST Frameworks, aber nachdem ich die Zeit und Arbeit investiert habe, sie zu untersuchen, habe ich festgestellt, dass viele nicht mehr unterstützt werden oder abgebrochen wurden und dass mehrere fortbestehende Probleme sie unpassend machten.
