还是使用 Python 类型声明，**FastAPI** 提供了（集成 Swagger UI 的）API 文档。

注意，路径参数的类型是整数。

## 基于标准的好处，备选文档

**FastAPI** 使用 <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md" class="external-link" target="_blank">OpenAPI</a> 生成概图，所以能兼容很多工具。

因此，**FastAPI** 还内置了 ReDoc 生成的备选 API 文档，可在此查看 <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>：

它可以：

* 在响应中返回状态码
* 在 OpenAPI 概图（及用户界面）中存档：

<img src="/img/tutorial/response-status-code/image01.png">

/// note | "笔记"

某些响应状态码表示响应没有响应体（参阅下一章）。

FastAPI 可以进行识别，并生成表明无响应体的 OpenAPI 文档。

///

## 关于 HTTP 状态码

/// note | "笔记"

如果已经了解 HTTP 状态码，请跳到下一章。

///

在 HTTP 协议中，发送 3 位数的数字状态码是响应的一部分。
