我的laravel帐户变得好坏参半

Question

我创建了一个laravel应用程序，其中的用户是普通用户和admin用户...我通过默认的laravel身份验证将它们都登录到网站...并且我有中间件来隐藏普通用户的某些路由。但是现在我遇到了一个大问题...有时，当我刷新页面时，我在另一个帐户中发现了自己（例如：现在我是约翰，刷新页面，然后发现了自己的茉莉花）！ ..我以前没有遇到过这样的问题:(，现在这个问题很少发生...我现在将应用程序托管在共享托管中。

   /* LoginController.php */
   public function login(Request $request){
   $this->validate($request,[
     'email' => 'required|email',
     'password' => 'required|string'
   ]);

   if(!\DB::table('users')->where('email',$request->email)->get()->count()){
     $errors = new \Illuminate\Support\MessageBag();

     // add your error messages:
     $errors->add('email', __('auth.failed'));

     return view('auth.login')->withErrors($errors);
   }
   // if(\DB::table('users')->where('email',$request->email)->first()->is_active == 2){
   //   return redirect('/activate-account');
   // }
   $binary = 0;
   if(\DB::table('users')->where('email',$request->email)->first()->role != 1) $binary = 1;
   // login the activated users only and remember them all the time
   if (\Auth::attempt(['email' => $request->email, 'password' => $request->password, 'is_active'=>1],$binary)) {
         // Authentication passed...
