* パラメータが**単数型** (`int`、`float`、`str`、`bool` など)の場合は**クエリ**パラメータとして解釈されます。
* パラメータが **Pydantic モデル**型で宣言された場合、リクエスト**ボディ**として解釈されます。

/// note | "備考"

FastAPIは、`= None`があるおかげで、`q`がオプショナルだとわかります。

`Optional[str]` の`Optional` はFastAPIでは使用されていません（FastAPIは`str`の部分のみ使用します）。しかし、`Optional[str]` はエディタがコードのエラーを見つけるのを助けてくれます。
