これまで`...`を見たことがない方へ: これは特殊な単一値です。<a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">Pythonの一部であり、"Ellipsis"と呼ばれています</a>。

これは **FastAPI** にこのパラメータが必須であることを知らせます。

## クエリパラメータのリスト / 複数の値

クエリパラメータを明示的に`Query`で宣言した場合、値のリストを受け取るように宣言したり、複数の値を受け取るように宣言したりすることもできます。

## 特殊な型とバリデーション

`str`や`int`、`float`のような通常の単数型の他にも、`str`を継承したより複雑な単数型を使うこともできます。

すべてのオプションをみるには、<a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Pydanticのエキゾチック な型</a>のドキュメントを確認してください。次の章でいくつかの例をみることができます。

例えば、`Image`モデルのように`url`フィールドがある場合、`str`の代わりにPydanticの`HttpUrl`を指定することができます:
