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。🤓

    @Test
    public void test_isUseTimeZoneHandling() {
        // Verify that time zone handling is disabled
        assertFalse(provider.isUseTimeZoneHandling());
    }

    // Test isAcceptCookieTimeZone() method
    @Test
    public void test_isAcceptCookieTimeZone() {
        // Verify that cookie time zone is not accepted
        assertFalse(provider.isAcceptCookieTimeZone());
    }

Örneğin, request'i işleyip response üretmenin kaç saniye sürdüğünü içeren `X-Process-Time` adlı özel bir header ekleyebilirsiniz:

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

/// tip | İpucu

Burada [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) yerine `time.time()` kullanıyoruz, çünkü bu kullanım senaryolarında daha hassas olabilir. 🤓
