Nós verificamos que nós obtemos um `username`, e extraímos os escopos.

E depois nós validamos esse dado com o modelo Pydantic (capturando a exceção `ValidationError`), e se nós obtemos um erro ao ler o token JWT ou validando os dados com o Pydantic, nós levantamos a exceção `HTTPException` que criamos anteriormente.

Para isso, nós atualizamos o modelo Pydantic `TokenData` com a nova propriedade `scopes`.

Le paramètre de requête `q` a pour type `Union[str, None]` (ou `str | None` en Python 3.10), signifiant qu'il est de type `str` mais pourrait aussi être égal à `None`, et bien sûr, la valeur par défaut est `None`, donc **FastAPI** saura qu'il n'est pas requis.

/// note

**FastAPI** saura que la valeur de `q` n'est pas requise grâce à la valeur par défaut `= None`.
