## Zusätzliche Response mit `model`

Sie können Ihren *Pfadoperation-Dekoratoren* einen Parameter `responses` übergeben.

Der nimmt ein `dict` entgegen, die Schlüssel sind Statuscodes für jede Response, wie etwa `200`, und die Werte sind andere `dict`s mit den Informationen für jede Response.

* <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#response-object" class="external-link" target="_blank">Objeto de Response de OpenAPI</a>, puedes incluir cualquier cosa de esto directamente en cada response dentro de tu parámetro `responses`. Incluyendo `description`, `headers`, `content`...

        assertNull(response2.getNextResponse());

        // Verify each response maintains its own notifications
        assertEquals(1, response1.getNotifyInformation().size());
        assertEquals(mockNotifyInfo1, response1.getNotifyInformation().get(0));

        assertEquals(1, response2.getNotifyInformation().size());
        assertEquals(mockNotifyInfo2, response2.getNotifyInformation().get(0));
    }

            assertEquals(10, response1.getChunksWritten());
            assertEquals(4096, response1.getChunkBytesWritten());
            assertEquals(40960, response1.getTotalBytesWritten());

            assertEquals(20, response2.getChunksWritten());
            assertEquals(8192, response2.getChunkBytesWritten());
            assertEquals(163840, response2.getTotalBytesWritten());
        }

Você pode declarar um `response_model`, utilizando o código de status padrão `200` (ou um customizado caso você precise), e depois adicionar informações adicionais para esse mesmo retorno em `responses`, diretamente no esquema OpenAPI.

O **FastAPI** manterá as informações adicionais do `responses`, e combinará com o esquema JSON do seu modelo.

## 组合信息
您还可以联合接收来自多个位置的响应信息，包括 `response_model `、 `status_code` 和 `responses `参数。

您可以使用默认的状态码 `200` （或者您需要的自定义状态码）声明一个 `response_model `，然后直接在OpenAPI模式中在 `responses` 中声明相同响应的其他信息。

**FastAPI**将保留来自 `responses` 的附加信息，并将其与模型中的JSON Schema结合起来。

例如，您可以使用状态码 `404` 声明响应，该响应使用`Pydantic`模型并具有自定义的` description` 。

      val code = response.code
      if (code != HTTP_TEMP_REDIRECT && code != HTTP_PERM_REDIRECT) return response
      val method = response.request.method
      if (method == "GET" || method == "HEAD") return response
      val location = response.header("Location") ?: return response
      return response
        .newBuilder()
        .removeHeader("Location")
        .header("LegacyRedirectInterceptor-Location", location)

        }

        String response2Body;
        try (Response response2 = client.newCall(request).execute()) {
          if (!response2.isSuccessful()) throw new IOException("Unexpected code " + response2);

          response2Body = response2.body().string();
          System.out.println("Response 2 response:          " + response2);

        assertEquals(0, response.writeDataWireFormat(null, 0));

        // Read methods return 0 without accessing null buffer
        assertEquals(0, response.readSetupWireFormat(null, 0, 0));
        assertEquals(0, response.readParametersWireFormat(null, 0, 0));
        assertEquals(0, response.readDataWireFormat(null, 0, 0));
    }

    @Test

    server.enqueue(MockResponse(body = "response that will never be received"))
    val response = executeSynchronously("/")
    response.assertFailure(
      // JDK 11 response to the FAIL_HANDSHAKE:
      SSLException::class.java,
      // RI response to the FAIL_HANDSHAKE:
      SSLProtocolException::class.java,
      // Android's response to the FAIL_HANDSHAKE:
      SSLHandshakeException::class.java,
