## Mettre à jour les dépendances { #update-the-dependencies }

Mettez à jour `get_current_user` pour recevoir le même jeton qu'auparavant, mais cette fois en utilisant des jetons JWT.

Décodez le jeton reçu, vérifiez-le, et renvoyez l'utilisateur courant.

## Обновление зависимостей { #update-the-dependencies }

Обновите `get_current_user` для получения того же токена, что и раньше, но на этот раз с использованием JWT-токенов.

Декодируйте полученный токен, проверьте его и верните текущего пользователя.
