# ボディ - 複数のパラメータ

これまで`Path`と`Query`をどう使うかを見てきましたが、リクエストボディの宣言のより高度な使い方を見てみましょう。

## `Path`、`Query`とボディパラメータを混ぜる

まず、もちろん、`Path`と`Query`とリクエストボディのパラメータの宣言は自由に混ぜることができ、 **FastAPI** は何をするべきかを知っています。

また、デフォルトの`None`を設定することで、ボディパラメータをオプションとして宣言することもできます:

{* ../../docs_src/body_multiple_params/tutorial001.py hl[19,20,21] *}

/// note | 備考

この場合、ボディから取得する`item`はオプションであることに注意してください。デフォルト値は`None`です。
