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

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

## Atualize a *operação de rota* `/token` { #update-the-token-path-operation }

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

Crie um token de acesso JWT real e o retorne.

### Redirecionamentos com HTTPS { #redirects-with-https }

Por exemplo, suponha que você defina uma *operação de rota* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py39.py hl[6] *}

Se o cliente tentar ir para `/items`, por padrão, ele seria redirecionado para `/items/`.

O jeito de usar é muito simples. Por exemplo, para fazer uma requisição `GET`, você escreveria:

```Python
response = requests.get("http://example.com/some/url")
```

A contra-parte na aplicação FastAPI, a operação de rota, poderia ficar assim:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Veja as similaridades em `requests.get(...)` e `@app.get(...)`.
