你可以在任何*路径操作*接收 `request` 之前，添加要与该 `request` 一起运行的代码。

也可以在生成 `response` 之后、返回之前添加代码。

例如，你可以添加一个自定义请求头 `X-Process-Time`，其值为处理请求并生成响应所花费的秒数：

{* ../../docs_src/middleware/tutorial001_py310.py hl[10,12:13] *}

/// tip

这里我们使用 [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) 而不是 `time.time()`，因为在这类场景中它可能更精确。🤓
