...以前の`common_parameters`と同じパラメータを持っています:

これらのパラメータは **FastAPI** が依存関係を「解決」するために使用するものです。

どちらの場合も以下を持っています:

* オプショナルの`q`クエリパラメータ。
* `skip`クエリパラメータ、デフォルトは`0`。
* `limit`クエリパラメータ、デフォルトは`100`。

どちらの場合も、データは変換され、検証され、OpenAPIスキーマなどで文書化されます。

## 使用

これで、このクラスを使用して依存関係を宣言することができます。

In this section you will see how to manage authentication and authorization with the same OAuth2 with scopes in your **FastAPI** application.

/// warning

This is a more or less advanced section. If you are just starting, you can skip it.

You don't necessarily need OAuth2 scopes, and you can handle authentication and authorization however you want.

But OAuth2 with scopes can be nicely integrated into your API (with OpenAPI) and your API docs.
