### Remotely Inspecting backend data

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

## Das `Request`-Objekt direkt verwenden { #use-the-request-object-directly }

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

Dazu müssen Sie direkt auf den Request zugreifen.

Nevertheless, as the **application server** doesn't know it is behind a trusted **proxy**, by default, it wouldn't trust those headers.

        .proxy(socksProxy.proxy())

      server
        .url("/")
        .newBuilder()
        .host(SocksProxy.HOSTNAME_THAT_ONLY_THE_PROXY_KNOWS)
        .build()
    val request = Request.Builder().url(url).build()
    val response1 = client.newCall(request).execute()

      mockServerClient

          request()
            .withPath("/person")
            .withQueryStringParameter("name", "peter"),

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

## Utilize o objeto `Request` diretamente { #use-the-request-object-directly }

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.
