**FastAPI**は、リクエストの**クエリパラメータ**からそれぞれの**フィールド**のデータを**抽出**し、定義したPydanticモデルを提供します。

## ドキュメントの確認 { #check-the-docs }

対話的APIドキュメント `/docs` でクエリパラメータを確認できます:

<div class="screenshot">
<img src="/img/tutorial/query-param-models/image01.png">
</div>

## 余分なクエリパラメータを禁止する { #forbid-extra-query-parameters }

特定の（あまり一般的ではないかもしれない）ユースケースで、受け取りたいクエリパラメータを**制限**したい場合があります。

Pydanticのモデル設定を使って、あらゆる `extra` フィールドを `forbid` にできます。
