* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).

## Use the `Request` object directly

Let's imagine you want to get the client's IP address/host inside of your *path operation function*.

For that you need to access the request directly.

```Python hl_lines="1  7-8"
{!../../docs_src/using_request_directly/tutorial001.py!}
```

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

mail.smtp.server.main.host.and.port = localhost:25

# The common return path of all mail
mail.return.path = root@localhost
