而不是局限于只能有一个返回该类型数据的依赖项。

///

## 其它模型

接下来，直接在*路径操作函数*中获取当前用户，并用 `Depends` 在**依赖注入**系统中处理安全机制。

开发者可以使用任何模型或数据满足安全需求（本例中是 Pydantic 的 `User` 模型）。

而且，不局限于只能使用特定的数据模型、类或类型。

不想在模型中使用 `username`，而是使用 `id` 和 `email`？当然可以。这些工具也支持。

只想使用字符串？或字典？甚至是数据库类模型的实例？工作方式都一样。

实际上，就算登录应用的不是用户，而是只拥有访问令牌的机器人、程序或其它系统？工作方式也一样。

尽管使用应用所需的任何模型、类、数据库。**FastAPI** 通过依赖注入系统都能帮您搞定。
