/// note | 注意

儘管 `item` 的宣告方式與先前相同，現在預期它會位於 body 內，且鍵為 `item`。

///

**FastAPI** 會自動從請求中進行轉換，讓參數 `item` 收到對應內容，`user` 亦同。

它會對複合資料進行驗證，並在 OpenAPI 結構與自動文件中如此描述。

## Body 中的單一值 { #singular-values-in-body }

就像你可以用 `Query` 與 `Path` 為查詢與路徑參數定義額外資訊一樣，**FastAPI** 也提供對應的 `Body`。

例如，延伸前述模型，你可以決定在相同的 Body 中，除了 `item` 與 `user` 外，還要有另一個鍵 `importance`。

如果直接這樣宣告，因為它是單一值，**FastAPI** 會將其視為查詢參數。
