    * Но для этого необходима аутентификация для конкретной конечной точки.
    * Поэтому для аутентификации в нашем API он посылает заголовок `Authorization` со значением `Bearer` плюс сам токен.
    * Если токен содержит `foobar`, то содержание заголовка `Authorization` будет таким: `Bearer foobar`.

Para esos casos, puedes usar un parámetro `Response`.

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de la operación de path* (como puedes hacer para cookies y headers).

Y luego puedes establecer el `status_code` en ese objeto de respuesta *temporal*.
