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。


## 代码大小 { #code-size }

这个示例看起来有些冗长。毕竟这个文件同时包含了安全、数据模型的工具函数，以及路径操作等代码。

但，关键是：

**安全和依赖注入的代码只需要写一次。**

就算写得再复杂，也只是在一个位置写一次就够了。所以，要多复杂就可以写多复杂。

但是，就算有数千个端点（*路径操作*），它们都可以使用同一个安全系统。

而且，所有端点（或它们的任何部件）都可以利用这些依赖项或任何其它依赖项。
