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`.

Se ele não ver o header de `Autorização` ou o valor não tem um token `Bearer`, vai responder com um código de erro  401 (`UNAUTHORIZED`) diretamente.

Você nem precisa verificar se o token existe para retornar um erro. Você pode ter certeza de que se a sua função for executada, ela terá um `str` nesse token.

Si no ve un header `Authorization`, o el valor no tiene un token `Bearer `, responderá directamente con un error de código de estado 401 (`UNAUTHORIZED`).

Ni siquiera tienes que verificar si el token existe para devolver un error. Puedes estar seguro de que si tu función se ejecuta, tendrá un `str` en ese token.

Puedes probarlo ya en los docs interactivos:
