Php 错误：419页已过期（Laravel6.0-Mysql）

我已经添加了

@csrf

标记，并以表单和头中的meta标记的形式添加，但仍然得到相同的错误。当我注册时，它会工作并将我重定向到主页。这很好，但当我登录时，它不会将我重定向到主页，尽管凭据是正常的

试着用
php-artisan-cache:clear
清除缓存，这通常对我来说很有用

## LoginController.php ##

存在版本差异问题中的上述代码是针对laravel framework 5.6的，我已经更新了laravel，laravel framework 6.15.1或6的代码在下面，这是唯一的问题

 protected function redirectTo( ) {

//        dd(Auth::user()->role);

        if (Auth::check() && Auth::user()->role == 'customer') {
            $this->redirectTo = '/customer';
            return $this->redirectTo;
        }
        elseif (Auth::check() && Auth::user()->role == 'agent') {
            $this->redirectTo = '/agent';
            return $this->redirectTo;
        }
        else {
            $this->redirectTo = '/admin';
            return $this->redirectTo;
        }

    }

检查
.env
文件和其中设置的驱动程序。请参阅-此异常是由内置Laravel的应用程序安全保护支持引起的。当我们在页面HTML正文中不包含CSRF_令牌表单输入时，可能会出现错误419或页面过期。这里没有答案。应为注释。ErrorException标题不能包含多个标题，新行detected@Salman如果您登录，是否会看到
echo“Hello{role}”？@Geertjankanapenno@Salman如果删除路线中的“管理员”、“代理”和“客户”中间产品，您是否看到回音？
 protected function redirectTo( ) {

//        dd(Auth::user()->role);

        if (Auth::check() && Auth::user()->role == 'customer') {
            $this->redirectTo = '/customer';
            return $this->redirectTo;
        }
        elseif (Auth::check() && Auth::user()->role == 'agent') {
            $this->redirectTo = '/agent';
            return $this->redirectTo;
        }
        else {
            $this->redirectTo = '/admin';
            return $this->redirectTo;
        }

    }
