Wenn Sie diese Sichtweise (des *externen Entwicklers*) vorübergehend übernehmen, wird es offensichtlicher, wo die Parameter, das Pydantic-Modell für den Body, die Response, usw. für diese *externe API* hingehören.

### Einen Callback-`APIRouter` erstellen

Erstellen Sie zunächst einen neuen `APIRouter`, der einen oder mehrere Callbacks enthält.

Bạn có thể trả về một `dict`, `list`, một trong những giá trị đơn như `str`, `int`,...

Bạn cũng có thể trả về Pydantic model (bạn sẽ thấy nhiều hơn về nó sau).

Có nhiều object và model khác nhau sẽ được tự động chuyển đổi sang JSON (bao gồm cả ORM,...). Thử sử dụng loại ưa thích của bạn, nó có khả năng cao đã được hỗ trợ.

## Tóm lại

Verificamos que obtenemos un `username`, y extraemos los scopes.

Y luego validamos esos datos con el modelo de Pydantic (capturando la excepción `ValidationError`), y si obtenemos un error leyendo el token JWT o validando los datos con Pydantic, lanzamos la `HTTPException` que creamos antes.

Para eso, actualizamos el modelo de Pydantic `TokenData` con una nueva propiedad `scopes`.

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`.
