例如，要声明另一个具有状态码 `404` 和`Pydantic`模型 `Message` 的响应，可以写：
{* ../../docs_src/additional_responses/tutorial001.py hl[18,22] *}

/// note

请记住，您必须直接返回 `JSONResponse` 。

///

/// info

`model` 密钥不是OpenAPI的一部分。
**FastAPI**将从那里获取`Pydantic`模型，生成` JSON Schema` ，并将其放在正确的位置。
- 正确的位置是：
    - 在键 `content` 中，其具有另一个`JSON`对象（ `dict` ）作为值，该`JSON`对象包含：
