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.

모델 등과 함께 직렬화되지 않습니다.

원하는 데이터가 있는지, 값이 유효한 JSON인지 확인합니다(`JSONResponse`를 사용하는 경우).

Para lograr eso, importa `JSONResponse`, y devuelve tu contenido allí directamente, configurando el `status_code` que deseas:

Cuando devuelves un `Response` directamente, como en el ejemplo anterior, se devuelve directamente.

No se serializará con un modelo, etc.

但是你也希望它能够接受新的条目。并且当这些条目不存在时，会自动创建并返回 201 「创建」的 HTTP 状态码。

要实现它，导入 `JSONResponse`，然后在其中直接返回你的内容，并将 `status_code` 设置为为你要的值。

/// warning | 警告

当你直接返回一个像上面例子中的 `Response` 对象时，它会直接返回。

FastAPI 不会用模型等对该响应进行序列化。

确保其中有你想要的数据，且返回的值为合法的 JSON（如果你使用 `JSONResponse` 的话）。

/// warning | 警告

可在一个*路径操作*中声明多个 `Form` 参数，但不能同时声明要接收 JSON 的 `Body` 字段。因为此时请求体的编码是 `application/x-www-form-urlencoded`，不是 `application/json`。

这不是 **FastAPI** 的问题，而是 HTTP 协议的规定。
