* 它接收你的应用的每一个**请求**。
* 然后它可以对这个**请求**做一些事情或者执行任何需要的代码。
* 然后它将这个**请求**传递给应用程序的其他部分（某个*路径操作*）处理。
* 之后它获取应用程序生成的**响应**（由某个*路径操作*产生）。
* 它可以对该**响应**做一些事情或者执行任何需要的代码。
* 然后它返回这个**响应**。

/// note | 技术细节

如果你有使用 `yield` 的依赖，依赖中的退出代码会在中间件之后运行。

如果有任何后台任务（会在[后台任务](background-tasks.md)一节中介绍，你稍后会看到），它们会在所有中间件之后运行。

///

## 创建中间件 { #create-a-middleware }

要创建中间件，你可以在函数的顶部使用装饰器 `@app.middleware("http")`。

中间件函数会接收：
