* 它可以对该**响应**做些什么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

如果你使用了 `yield` 关键字依赖, 依赖中的退出代码将在执行中间件*后*执行.

如果有任何后台任务(稍后记录), 它们将在执行中间件*后*运行.

///

## 创建中间件

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

中间件参数接收如下参数:

* `request`.
* 一个函数 `call_next` 它将接收 `request` 作为参数.
    * 这个函数将 `request` 传递给相应的 *路径操作*.
    * 然后它将返回由相应的*路径操作*生成的 `response`.
* 然后你可以在返回 `response` 前进一步修改它.
