### Abhängigkeiten mit `yield` und `scope` { #dependencies-with-yield-and-scope }

In Version 0.121.0 hat FastAPI Unterstützung für `Depends(scope="function")` für Abhängigkeiten mit `yield` hinzugefügt.

/// note | 笔记

注意，请求中 `Authorization` 响应头的值以 `Bearer` 开头。

## `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。
