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:

and Android! Please report any issues you encounter: we'll fix them urgently.

 *  Fix: Attempt to read the response body even if the server canceled the request. This will cause
    some calls to return nice error codes like `HTTP/1.1 429 Too Many Requests` instead of transport
    errors like `SocketException: Connection reset` and `StreamResetException: stream was reset:
    CANCEL`.
 *  New: Support OSGi metadata.

### 覆寫 `HTTPException` 的錯誤處理器 { #override-the-httpexception-error-handler }

同樣地，你也可以覆寫 `HTTPException` 的處理器。

例如，你可能想在這些錯誤時回傳純文字而非 JSON：
