Irá y buscará en el request ese header `Authorization`, verificará si el valor es `Bearer ` más algún token, y devolverá el token como un `str`.

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.

#### Wofür OpenAPI gedacht ist

* The frontend (running in the user's browser) sends that `username` and `password` to a specific URL in our API (declared with `tokenUrl="token"`).
* The API checks that `username` and `password`, and responds with a "token" (we haven't implemented any of this yet).
    * A "token" is just a string with some content that we can use later to verify this user.
    * Normally, a token is set to expire after some time.

Puedes escribir mensajes en el cuadro de entrada y enviarlos:

Y tu aplicación **FastAPI** con WebSockets responderá de vuelta:

Puedes enviar (y recibir) muchos mensajes:

Y todos usarán la misma conexión WebSocket.
