Y todas estas miles de *path operations* pueden ser tan pequeñas como 3 líneas:

## Resumen { #recap }

Ahora puedes obtener el usuario actual directamente en tu *path operation function*.

Ya estamos a mitad de camino.

安全與依賴注入相關的內容只需要寫一次。

你可以把它設計得再複雜都沒問題，仍然只需在單一位置寫一次，依然具備完整的彈性。

但你可以有成千上萬個端點（*路徑操作*）共用同一套安全系統。

而且它們全部（或你想要的一部分）都可以重用這些依賴，或你建立的其他依賴。

而所有這些上千個*路徑操作*都可以小到只要 3 行：

{* ../../docs_src/security/tutorial002_an_py310.py hl[30:32] *}

## 回顧 { #recap }

現在你可以在*路徑操作函式*中直接取得目前使用者。

我們已經完成一半了。

我們只需要再新增一個*路徑操作*，讓使用者/用戶端實際送出 `username` 與 `password`。
