上述这些操作都是可行的，**FastAPI** 知道该怎么处理。

## 与 OpenAPI 集成

依赖项及子依赖项的所有请求声明、验证和需求都可以集成至同一个 OpenAPI 概图。

所以，交互文档里也会显示依赖项的所有信息：

## 简单用法

观察一下就会发现，只要*路径* 和*操作*匹配，就可以使用声明的路径操作函数。然后，**FastAPI** 会用正确的参数调用函数，并提取请求中的数据。

## OpenAPI and API docs

If you return additional status codes and responses directly, they won't be included in the OpenAPI schema (the API docs), because FastAPI doesn't have a way to know beforehand what you are going to return.
