## `scopes` 高级用法

OAuth2 支持**`scopes`**（作用域）。

**`scopes`**为 JWT 令牌添加指定权限。

让持有令牌的用户或第三方在指定限制条件下与 API 交互。

**高级用户指南**中将介绍如何使用 `scopes`，及如何把 `scopes` 集成至 **FastAPI**。

## 小结

至此，您可以使用 OAuth2 和 JWT 等标准配置安全的 **FastAPI** 应用。

几乎在所有框架中，处理安全问题很快都会变得非常复杂。

 * <p>Data stores are registered by name and class name, allowing flexible lookup.
 * The factory also supports dynamic discovery of data store plugins by scanning

## Продвинутое использование `scopes` { #advanced-usage-with-scopes }

В OAuth2 существует понятие "диапазоны" ("`scopes`").

С их помощью можно добавить определенный набор разрешений к JWT-токену.

Die Instanz der Klassenabhängigkeit `OAuth2PasswordRequestForm` verfügt, statt eines Attributs `scope` mit dem durch Leerzeichen getrennten langen String, über das Attribut `scopes` mit einer tatsächlichen Liste von Strings, einem für jeden gesendeten Scope.

In diesem Beispiel verwenden wir keine `scopes`, aber die Funktionalität ist vorhanden, wenn Sie sie benötigen.
