但這還不太有用。

讓它改為回傳目前使用者吧。

## 建立使用者模型 { #create-a-user-model }

先建立一個 Pydantic 的使用者模型。

就像用 Pydantic 宣告請求體一樣，我們也可以在其他地方使用它：

{* ../../docs_src/security/tutorial002_an_py310.py hl[5,12:6] *}

## 建立 `get_current_user` 依賴 { #create-a-get-current-user-dependency }

讓我們建立一個依賴 `get_current_user`。

記得依賴可以有子依賴嗎？
