Aktualisieren Sie `get_current_user`, um den gleichen Token wie zuvor zu erhalten, dieses Mal jedoch unter Verwendung von JWT-Tokens.

Dekodieren Sie den empfangenen Token, validieren Sie ihn und geben Sie den aktuellen Benutzer zurück.

Wenn der Token ungültig ist, geben Sie sofort einen HTTP-Fehler zurück.

## Die *Pfadoperation* `/token` aktualisieren { #update-the-token-path-operation }

Actualiza `get_current_user` para recibir el mismo token que antes, pero esta vez, usando tokens JWT.

Decodifica el token recibido, verifícalo y devuelve el usuario actual.

Si el token es inválido, devuelve un error HTTP de inmediato.

## Token’ı Döndürme { #return-the-token }

`token` endpoint’inin response’u bir JSON object olmalıdır.

Bir `token_type` içermelidir. Biz "Bearer" token’ları kullandığımız için token type "`bearer`" olmalıdır.

Ayrıca `access_token` içermelidir; bunun değeri access token’ımızı içeren bir string olmalıdır.

Bu basit örnekte tamamen güvensiz davranıp token olarak aynı `username`’i döndüreceğiz.

Update `get_current_user` to receive the same token as before, but this time, using JWT tokens.

Decode the received token, verify it, and return the current user.

If the token is invalid, return an HTTP error right away.

## Devolver el token { #return-the-token }

El response del endpoint `token` debe ser un objeto JSON.

Debe tener un `token_type`. En nuestro caso, como estamos usando tokens "Bearer", el tipo de token debe ser "`bearer`".

Y debe tener un `access_token`, con un string que contenga nuestro token de acceso.

Atualize `get_current_user` para receber o mesmo token de antes, mas desta vez, usando tokens JWT.

Decodifique o token recebido, verifique-o e retorne o usuário atual.

Se o token for inválido, retorne um erro HTTP imediatamente.

Die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> des `token`-Endpunkts muss ein JSON-Objekt sein.

Es sollte einen `token_type` haben. Da wir in unserem Fall „Bearer“-Token verwenden, sollte der Token-Typ „`bearer`“ sein.
