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。🤓

`status_code` 参数接收表示 HTTP 状态码的数字。

/// info | 信息

`status_code` 还能接收 `IntEnum` 类型，比如 Python 的 [`http.HTTPStatus`](https://docs.python.org/3/library/http.html#http.HTTPStatus)。

///

它可以：

* 在响应中返回状态码
* 在 OpenAPI 概图（及用户界面）中存档：

<img src="/img/tutorial/response-status-code/image01.png">

/// note | 注意

某些响应状态码表示响应没有响应体（参阅下一章）。

{* ../../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. 🤓

/// tip | Совет

Мы используем [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) вместо `time.time()` для обеспечения большей точности в таких случаях. 🤓

Here we use [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) instead of `time.time()` because it can be more precise for these use cases. 🤓
