每个响应字典都可以有一个关键模型，其中包含一个 `Pydantic` 模型，就像 `response_model` 一样。

**FastAPI**将采用该模型，生成其`JSON Schema`并将其包含在`OpenAPI`中的正确位置。

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：

	return "hello" + string(es), nil
