But first, let's check some small concepts.

## In a hurry? { #in-a-hurry }

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.

Cette même technique s'applique à `Query`, `Cookie` et `Header`. 😎

## Déclarer des cookies avec un modèle Pydantic { #cookies-with-a-pydantic-model }

Déclarez les paramètres de **cookie** dont vous avez besoin dans un **modèle Pydantic**, puis déclarez le paramètre comme `Cookie` :

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

       * requireNonNull is safe because we don't clear nextPermutation until we're done calling this

## Renvoyer une `Response` personnalisée { #returning-a-custom-response }

L'exemple ci-dessus montre toutes les parties dont vous avez besoin, mais il n'est pas encore très utile, car vous auriez pu renvoyer l'`item` directement, et **FastAPI** l'aurait placé dans une `JSONResponse` pour vous, en le convertissant en `dict`, etc. Tout cela par défaut.
