## Advanced usage with `scopes`

OAuth2 has the notion of "scopes".

You can use them to add a specific set of permissions to a JWT token.

Then you can give this token to a user directly or a third party, to interact with your API with a set of restrictions.

You can learn how to use them and how they are integrated into **FastAPI** later in the **Advanced User Guide**.

## Recap

### Return a Response Directly

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md){.internal-link target=_blank}.

```Python hl_lines="8  10-11"
{!> ../../../docs_src/response_model/tutorial003_02.py!}
```

Right as we wanted it. ✔️

This is because FastAPI uses this `root_path` to create the default `server` in OpenAPI with the URL provided by `root_path`.

## Additional servers

!!! warning
    This is a more advanced use case. Feel free to skip it.

By default, **FastAPI** will create a `server` in the OpenAPI schema with the URL for the `root_path`.

    all those dependencies in a single place.

    Read more about it in the
    [FastAPI docs for OAuth2 scopes](https://fastapi.tiangolo.com/advanced/security/oauth2-scopes/).
    """

    def __init__(
        self,
        scopes: Annotated[
            Optional[List[str]],
            Doc(
                """

    * You can also add [`Security` dependencies with `scopes`](../advanced/security/oauth2-scopes.md){.internal-link target=_blank}.

!!! tip

    相対URLを使っているので、APIが`https://example.com/`にある場合、`https://example.com/token`を参照します。しかし、APIが`https://example.com/api/v1/`にある場合は`https://example.com/api/v1/token`を参照することになります。

    相対 URL を使うことは、[プロキシと接続](../../advanced/behind-a-proxy.md){.internal-link target=_blank}のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。

このパラメーターはエンドポイント/ *path operation*を作成しません。しかし、URL`/token`はクライアントがトークンを取得するために使用するものであると宣言します。この情報は OpenAPI やインタラクティブな API ドキュメントシステムで使われます。

    db_user = crud.get_user(db, user_id=user_id)
    ...

## 迁移

### Eine Response direkt zurückgeben

Der häufigste Anwendungsfall ist, wenn Sie [eine Response direkt zurückgeben, wie es später im Handbuch für fortgeschrittene Benutzer erläutert wird](../advanced/response-directly.md){.internal-link target=_blank}.

```Python hl_lines="8  10-11"
{!> ../../../docs_src/response_model/tutorial003_02.py!}
