/// note

请注意，即使 `item` 的声明方式与之前相同，但现在它被期望通过 `item` 键内嵌在请求体中。

///

**FastAPI** 将自动对请求中的数据进行转换，因此 `item` 参数将接收指定的内容，`user` 参数也是如此。

它将执行对复合数据的校验，并且像现在这样为 OpenAPI 模式和自动化文档对其进行记录。

## 请求体中的单一值

        "price": 42.0,

}
```

/// note | "備考"

以前と同じように`item`が宣言されていたにもかかわらず、`item`はキー`item`を持つボディの内部にあることが期待されていることに注意してください。

///

**FastAPI** はリクエストから自動で変換を行い、パラメータ`item`が特定の内容を受け取り、`user`も同じように特定の内容を受け取ります。

複合データの検証を行い、OpenAPIスキーマや自動ドキュメントのように文書化してくれます。

## ボディ内の単数値
