## 將它宣告為參數 { #declare-it-as-a-parameter }

要把它加到你的*路徑操作（path operation）*中，宣告方式與路徑與查詢參數相同：

{* ../../docs_src/body/tutorial001_py310.py hl[16] *}

...並將其型別宣告為你建立的模型 `Item`。

## 效果 { #results }

只靠這樣的 Python 型別宣告，**FastAPI** 會：

- 將請求本文讀取為 JSON。
- （必要時）轉換為對應的型別。
- 驗證資料。
    - 若資料無效，會回傳清楚易懂的錯誤，指出哪裡、哪筆資料不正確。
- 把接收到的資料放在參數 `item` 中提供給你。
    - 由於你在函式中將其宣告為 `Item` 型別，你也會獲得完整的編輯器支援（自動完成等）以及所有屬性與其型別。
