!!! tip
    Here `tokenUrl="token"` refers to a relative URL `token` that we haven't created yet. As it's a relative URL, it's equivalent to `./token`.

    Because we are using a relative URL, if your API was located at `https://example.com/`, then it would refer to `https://example.com/token`. But if your API was located at `https://example.com/api/v1/`, then it would refer to `https://example.com/api/v1/token`.

## Den Benutzer holen

`get_current_user` wird eine von uns erstellte (gefakte) Hilfsfunktion verwenden, welche einen Token vom Typ `str` entgegennimmt und unser Pydantic-`User`-Modell zurückgibt:
