Question

  ""  stcuked with this issue any solution please let me knw...  "" 


public function confirm($token){
               // $user =\DB::table('users')->where('confirmation_token',$token)->firstOrFail(); 
               // $token = User::findorFail($token);
                $user =\DB::table('users')->where('confirmation_token',$token)->firstOrFail();
               // User::where('confirmation_token',$token)->first();
                if (!$user) {
                  return response()->json([
                 'message'=> 'this activation token is invalid'
                ]);
                }
                  $user ->confirmed = User::CONFIRMEDEMAIL_USER;
                  $user->confirmation_token = null;
                  $user->save();
                  return $this->showMessage('the account verified');
                }

如何使用各种可能性解决此问题，并给出相同的错误      “ message”：“没有模型[App \ User]的查询结果。”，         “ exception”：“ Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException”，         “文件”：“ / home / aoudhesh / Downloads / stigitel / vendor / laravel / framework / src / Illuminate / Foundation / Exceptions / Handler.php”，         “行”：200，
