記得依賴可以有子依賴嗎？

`get_current_user` 會依賴我們先前建立的相同 `oauth2_scheme`。

如同先前在*路徑操作*中直接做的一樣，新的依賴 `get_current_user` 會從子依賴 `oauth2_scheme` 接收一個作為 `str` 的 `token`：

{* ../../docs_src/security/tutorial002_an_py310.py hl[25] *}

## 取得使用者 { #get-the-user }

`get_current_user` 會使用我們建立的（假的）工具函式，它接收一個作為 `str` 的 token，並回傳我們的 Pydantic `User` 模型：

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## 注入目前使用者 { #inject-the-current-user }

Так само, як ми робили раніше безпосередньо в операції шляху, наша нова залежність `get_current_user` отримає `token` як `str` від підзалежності `oauth2_scheme`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[25] *}

## Отримати користувача { #get-the-user }

`get_current_user` використає (фальшиву) утилітну функцію, яку ми створили, що приймає `token` як `str` і повертає нашу Pydantic-модель `User`:
