예를 들어 항목을 업데이트할 수 있는 *경로 작업*이 있고 성공 시 200 “OK”의 HTTP 상태 코드를 반환한다고 가정해 보겠습니다.

하지만 새로운 항목을 허용하기를 원할 것입니다. 항목이 이전에 존재하지 않았다면 이를 생성하고 HTTP 상태 코드 201 "Created"를 반환합니다.

이를 위해서는 `JSONResponse`를 가져와서 원하는 `status_code`를 설정하여 콘텐츠를 직접 반환합니다:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning | 경고

위의 예제처럼 `Response`를 직접 반환하면 바로 반환됩니다.

    Entry<K, V>[] entries2 = (Entry<K, V>[]) entries;
    return copyOf(Arrays.asList(entries2));
  }

   * Returns a new builder. The generated builder is equivalent to the builder created by the {@link

    return new Builder<>();
  }

# 响应 - 更改状态码

你可能之前已经了解到，你可以设置默认的[响应状态码](../tutorial/response-status-code.md){.internal-link target=_blank}。

但在某些情况下，你需要返回一个不同于默认值的状态码。

## 使用场景

例如，假设你想默认返回一个HTTP状态码为“OK”`200`。

但如果数据不存在，你想创建它，并返回一个HTTP状态码为“CREATED”`201`。

但你仍然希望能够使用`response_model`过滤和转换你返回的数据。

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。

     *
     * @param <T>
     *            The type of the instance to be created
     * @param className
     *            The class name. Must not be {@literal null} or empty.
     * @return A new object created by invoking the default constructor
     * @throws ClassNotFoundRuntimeException
     *             If the class cannot be found
