## Atualize as dependências

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.

{* ../../docs_src/security/tutorial004_an_py310.py hl[90:107] *}

## Atualize a *operação de rota* `/token`

Crie um `timedelta` com o tempo de expiração do token.

Isso irá validar os dados, mostrar um erro claro quando os dados forem inválidos, e documentar o parâmetro na *operação de rota* do esquema OpenAPI..

## Adicionando mais validações

Você também pode incluir um parâmetro `min_length`:
