## 与 OpenAPI 集成 { #integrated-with-openapi }

依赖项及子依赖项中声明的所有请求、验证和需求都会集成到同一个 OpenAPI 模式中。

因此，交互式文档中也会包含这些依赖项的所有信息：

<img src="/img/tutorial/dependencies/image01.png">

## 简单用法 { #simple-usage }

观察一下就会发现，只要*路径*和*操作*匹配，就会使用声明的*路径操作函数*。随后，**FastAPI** 会用正确的参数调用该函数，并从请求中提取数据。

事实上，所有（或大多数）Web 框架的工作方式都是这样的。

你从不会直接调用这些函数。它们由你的框架（此处为 **FastAPI**）调用。

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Mais FastAPI (en fait Starlette) fournit une manière plus simple de le faire, qui garantit que les middlewares internes gèrent les erreurs serveur et que les gestionnaires d'exceptions personnalisés fonctionnent correctement.

Então, a documentação interativa também terá toda a informação sobre essas dependências:
