## パラメータとして宣言 { #declare-it-as-a-parameter }

*path operation* に追加するには、パスパラメータやクエリパラメータを宣言したのと同じ方法で宣言します:

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

...そして、作成したモデル `Item` を型として宣言します。

## 結果 { #results }

そのPythonの型宣言だけで **FastAPI** は以下を行います:

* リクエストのボディをJSONとして読み取ります。
* 対応する型に変換します（必要な場合）。
* データを検証します。
    * データが無効な場合は、どこで何が不正なデータだったのかを正確に示す、分かりやすい明確なエラーを返します。
* 受け取ったデータをパラメータ `item` に渡します。
