/// tip | Подсказка
У экземпляра зависимости `OAuth2PasswordRequestForm` не будет атрибута `scope` с длинной строкой, разделенной пробелами. Вместо этого будет атрибут `scopes` со списком отдельных строк — по одной для каждого переданного scope.

В данном примере мы не используем `scopes`, но если вам это необходимо, функциональность есть.

## 進階用法：`scopes` { #advanced-usage-with-scopes }

OAuth2 有「scopes」的概念。

你可以用它們替 JWT 權杖加上一組特定的權限。

接著你可以把這個權杖直接交給某個使用者或第三方，讓他們在一組受限條件下與你的 API 互動。

你可以在之後的「進階使用者指南」學到如何使用它們，以及它們如何整合進 **FastAPI**。
