You need to use the Auth facade in the controller;
您需要在控制器中使用 Auth 门面；
add this line just before class definition.
在类定义之前添加这一行。
use Auth;

When you try to get the user by using $user = Auth::user();Laravel tries to load Auth class from the current location. In your case, it is
当您尝试使用$user = Auth::user();Laravel获取用户时，会尝试从当前位置加载 Auth 类。在你的情况下，它是
'App\Http\Controllers\Frontend'
'应用\Http\控制器\前端'
So Laravel is looking for Auth class inside the Frontend directory, which is not in. That's why you got that error message saying not found as below,
所以 Laravel 正在寻找 Frontend 目录中的 Auth 类，它不在。这就是为什么你收到错误消息说找不到如下，
'Class 'App\Http\Controllers\Frontend\Auth' not found'
'找不到类'App\Http\Controllers\Frontend\Auth'
If you use use Auth;method, you have to type use Auth;in each and every controller that you are going to use the Auth controller.
如果使用use Auth;方法，则必须输入use Auth;要使用 Auth 控制器的每个控制器。
Instead of typing use Auth;in each and every controller you can simply use the Laravel helper function as auth()->user().
而不是输入的use Auth;在每一个控制器，你可以简单地使用Laravel的辅助功能auth()->user()。
from that you can get any value from the db like:
从中您可以从数据库中获取任何值，例如：
auth()->user()->id
auth()->user()->f_name
