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`。

/// info | 信息
