不過，其他以一般方式宣告的參數（例如以 Pydantic 模型宣告的 body）仍然會被驗證、轉換、加上標註等。

但在某些特定情境下，直接取得 `Request` 物件會很實用。

## 直接使用 `Request` 物件 { #use-the-request-object-directly }

假設你想在你的 路徑操作函式（path operation function） 中取得用戶端的 IP 位址／主機。

為此，你需要直接存取請求。

{* ../../docs_src/using_request_directly/tutorial001_py310.py hl[1,7:8] *}

只要在 路徑操作函式 中宣告一個型別為 `Request` 的參數，FastAPI 就會將當前的 `Request` 傳入該參數。
