O **FastAPI** pegará este modelo, gerará o esquema JSON dele e incluirá no local correto do OpenAPI.

Por exemplo, para declarar um outro retorno com o status code `404` e um modelo do Pydantic chamado `Message`, você pode escrever:

{* ../../docs_src/additional_responses/tutorial001_py310.py hl[18,22] *}

/// note | Nota

Lembre-se que você deve retornar o `JSONResponse` diretamente.

각 응답 `dict`에는 `response_model`처럼 Pydantic 모델을 담는 `model` 키가 있을 수 있습니다.

**FastAPI**는 그 모델을 사용해 JSON Schema를 생성하고, OpenAPI의 올바른 위치에 포함합니다.

예를 들어, 상태 코드 `404`와 Pydantic 모델 `Message`를 사용하는 다른 응답을 선언하려면 다음과 같이 작성할 수 있습니다:

{* ../../docs_src/additional_responses/tutorial001_py310.py hl[18,22] *}

/// note | 참고

`JSONResponse`를 직접 반환해야 한다는 점을 기억하세요.

///

它接收一个 `dict`：键是每个响应的状态码（例如 `200`），值是包含该响应信息的另一个 `dict`。

这些响应的每个 `dict` 都可以有一个键 `model`，包含一个 Pydantic 模型，就像 `response_model` 一样。

**FastAPI** 会获取该模型，生成它的 JSON Schema，并将其放在 OpenAPI 中的正确位置。

例如，要声明另一个状态码为 `404` 且具有 Pydantic 模型 `Message` 的响应，你可以这样写：

{* ../../docs_src/additional_responses/tutorial001_py310.py hl[18,22] *}

/// note | 注意

记住你需要直接返回 `JSONResponse`。
