但我不能完全理解 UserRepository 和 AuthenticateUser , 为什么我们要这样使用它们，而不是简单地将功能放在用户模型和用户控制器和 AuthController 上？
原因是 UserRepository 等 类 处理特定功能，因此您根据需要注入这些对象。将所有这些放在一起仍然可以工作，但是如果您没有明确的关注点分离，则很难长期维护 运行。
The value of separation of concerns is simplifying development and
maintenance of computer programs. When concerns are well-separated,
individual sections can be reused, as well as developed and updated
independently. Of special value is the ability to later improve or
modify one section of code without having to know the details of other
sections, and without having to make corresponding changes to those
sections.
