php - 检查用户角色时出错 - 在 null 上调用成员函数 hasRole()

Question

我们有全新的 Laravel 和 voyager 管理面板。我们正在尝试检查用户角色，但它不起作用。

use Illuminate\Support\Facades\Auth;
use TCG\Voyager\Voyager;


class Controller extends BaseController
{
     use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

     public $auth, $user, $admin_role;

     public function __construct()
    {
         $this->auth = Auth::user();
         $this->user = Auth::check();
         $this->admin_role = $this->auth->hasRole('admin');
    }

    public function displayPassportInfo()
    {
        if ($this->user){
            if($this->admin_role) return view('passport');
            else return view('404');
        }
    }
}

在phpstorm应用程序中，在Illumination\contract中找不到方法hasRole...问题出在哪里？

这是每日日志文件的一部分。请帮助我以某种方式检查用户角色或权限。我们该如何解决？
