Es ist so konzipiert, dass es über Funktionen verfügt, welche zwei Parameter empfangen, einen „Request“ und eine „Response“. Dann „lesen“ Sie Teile des Requests und „schreiben“ Teile der Response. Aufgrund dieses Designs ist es nicht möglich, Request-Parameter und -Bodys mit Standard-Python-Typhinweisen als Funktionsparameter zu deklarieren.

And if you go to <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> you will see the response from FastAPI:

```JSON

    "message": "Hello World"
}

    Request request = new Request.Builder()
        .url("https://publicobject.com/robots.txt")
        .build();

    try (Response response = client.newCall(request).execute()) {
      if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

      for (Certificate certificate : response.handshake().peerCertificates()) {
        System.out.println(CertificatePinner.pin(certificate));
      }
    }
  }

        requestBody.put("sort_order", 1);
        checkMethodBase(requestBody).put("/api/admin/webconfig/setting").then().body("response.created", equalTo(true))

### Before and after the `response`

You can add code to be run with the `request`,  before any *path operation* receives it.

And also after the `response` is generated, before returning it.

For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

```Python hl_lines="10  12-13"
