你可以在任何*路徑操作*接收 `request` 之前，加入要執行的程式碼。

也可以在產生出 `response` 之後、回傳之前執行程式碼。

例如，你可以新增一個自訂標頭 `X-Process-Time`，其內容為處理請求並產生回應所花費的秒數：

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

/// tip

這裡我們使用 [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) 而不是 `time.time()`，因為在這些用例中它可能更精確。🤓
