## Récupérer l'utilisateur { #get-the-user }

`get_current_user` utilisera une fonction utilitaire (factice) que nous avons créée, qui prend un token en `str` et retourne notre modèle Pydantic `User` :

Si necesitas GraphQL, aún te recomendaría revisar [Strawberry](https://strawberry.rocks/), ya que se basa en anotaciones de tipos en lugar de clases y tipos personalizados.
