En este ejemplo, los mensajes se escribirán en el archivo `log.txt` *después* de que se envíe el response.

Si hay un query en el request, se escribirá en el log en una tarea en segundo plano.

Y luego otra tarea en segundo plano generada en la *path operation function* escribirá un mensaje usando el parámetro de path `email`.

## Multiple body params and query { #multiple-body-params-and-query }

Of course, you can also declare additional query parameters whenever you need, additional to any body parameters.

As, by default, singular values are interpreted as query parameters, you don't have to explicitly add a `Query`, you can just do:

```Python
q: Union[str, None] = None
```
