!!! check "检查"

    **FastAPI** 使用 Python 类型声明实现了数据校验。

    注意，上面的错误清晰地指出了未通过校验的具体原因。

    这在开发调试与 API 交互的代码时非常有用。

## 查看文档

访问 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>，查看自动生成的 API 文档：

!!! check "检查"

    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。
