Es gibt jedoch bestimmte Fälle, in denen es nützlich ist, auf das `Request`-Objekt zuzugreifen.

## Das `Request`-Objekt direkt verwenden

Angenommen, Sie möchten auf die IP-Adresse/den Host des Clients in Ihrer *Pfadoperation-Funktion* zugreifen.

Dazu müssen Sie direkt auf den Request zugreifen.

そして、チュートリアルと同様な方法でアプリケーションを起動して下さい。ただし、以下の様に`--reload` オプションは使用しないで下さい:

//// tab | Uvicorn

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

<span style="color: green;">INFO</span>:     Uvicorn running on http://0.0.0.0:80 (Press CTRL+C to quit)
```

//// tab | Hypercorn

<div class="termy">

}

func (driver *ftpDriver) getMinIOClient(ctx *ftp.Context) (*minio.Client, error) {
	tr := http.RoundTripper(globalRemoteFTPClientTransport)
	if host, _, err := net.SplitHostPort(ctx.Sess.RemoteAddr().String()); err == nil {
		tr = forwardForTransport{tr: tr, fwd: host}
	}
	ui, ok := globalIAMSys.GetUser(context.Background(), ctx.Sess.LoginUser())
	if !ok && !globalIAMSys.LDAPConfig.Enabled() {
		return nil, errNoSuchUser
	}

Mas há situações específicas onde é útil utilizar o objeto `Request`.

## Utilize o objeto `Request` diretamente

Vamos imaginar que você deseja obter o endereço de IP/host do cliente dentro da sua *função de operação de rota*.

Para isso você precisa acessar a requisição diretamente.
