注意我們把 `current_user` 的型別宣告為 Pydantic 的 `User` 模型。

這能在函式內提供自動補全與型別檢查的協助。

/// tip | 提示

你可能記得，請求體也會用 Pydantic 模型宣告。

這裡因為你使用了 `Depends`，**FastAPI** 不會混淆。

///

/// check | 檢查

這個依賴系統的設計讓我們可以有不同的依賴（不同的 "dependables"），都回傳 `User` 模型。

我們不受限於只能有一個能回傳該類型資料的依賴。

///

## 其他模型 { #other-models }

現在你可以在*路徑操作函式*中直接取得目前使用者，並在**依賴注入**層處理安全機制，使用 `Depends`。
