## Den `username` und das Format der Daten überprüfen

Wir verifizieren, dass wir einen `username` erhalten, und extrahieren die Scopes.

Und dann validieren wir diese Daten mit dem Pydantic-Modell (wobei wir die `ValidationError`-Exception abfangen), und wenn wir beim Lesen des JWT-Tokens oder beim Validieren der Daten mit Pydantic einen Fehler erhalten, lösen wir die zuvor erstellte `HTTPException` aus.

## Verify the `username` and data shape { #verify-the-username-and-data-shape }

We verify that we get a `username`, and extract the scopes.

And then we validate that data with the Pydantic model (catching the `ValidationError` exception), and if we get an error reading the JWT token or validating the data with Pydantic, we raise the `HTTPException` we created before.

For that, we update the Pydantic model `TokenData` with a new property `scopes`.

## Verifique o `username` e o formato dos dados

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.
