Se ele não ver o header de `Autorização` ou o valor não tem um token `Bearer`, vai responder com um código de erro  401 (`UNAUTHORIZED`) diretamente.

Você nem precisa verificar se o token existe para retornar um erro. Você pode ter certeza de que se a sua função for executada, ela terá um `str` nesse token.

Você já pode experimentar na documentação interativa:

L'idée de déclarer plusieurs choses (validation des données, sérialisation et documentation) avec les mêmes types Python, tout en offrant un excellent support pour les éditeurs, était pour moi une idée brillante.

## Démarrage rapide

Il existe 2 manières d'essayer Fess. La première est de le télécharger et l'installer vous-même. La seconde est d'utiliser [Docker](https://www.docker.com/products/docker-engine).

### Télécharger et Installer/Exécuter

Once the response has been received, the connection will be returned to the pool so it can be reused for a future request. Connections are evicted from the pool after a period of inactivity.

Pour revenir à l'exemple de code précédent, **FastAPI** permet de :

* Valider que `item_id` existe dans le chemin des requêtes `GET` et `PUT`.
* Valider que `item_id` est de type `int` pour les requêtes `GET` et `PUT`.
    * Si ce n'est pas le cas, le client voit une erreur utile et claire.
* Vérifier qu'il existe un paramètre de requête facultatif nommé `q` (comme dans `http://127.0.0.1:8000/items/foo?q=somequery`) pour les requêtes `GET`.
