解决laravel session失效的问题

<?php namespace App/Http/Controllers;use App/Http/Requests;use Request;use Illuminate/Support/Facades/Session; class CommonController extends Controller{  static function login(){    $team_id=Request::input('team_id');    $uuid=Request::input('uuid');    $key=Request::input('key');    if(empty($team_id)){      $team_id=Session::get('team_id');    }    if(empty($uuid)){      $uuid=Session::get('uuid');    }    if(empty($key)){      $key=Session::get('key');    }//    session(['team_id'=>$team_id]);    Session::put('team_id',$team_id);    Session::put('uuid',$uuid);    Session::put('key',$key);    Session::save();  }  public static function islogin(){    $team_id=Session::get('team_id');    $uuid=Session::get('uuid');    $key=Session::get('key');    if(!empty($team_id)&&!empty($uuid)){      if($key != 1234){        echo "没有权限";        exit;      }    }else{      echo "没有权限";      exit;    }  }}

Route::group(['middleware'=>'web'],function() {  Route::any('/report/billviews', 'report/UserbillController@BillViews');  Route::any('/report/index','report/UseraccessController@index');//把需要用到session的路由请求全部放在web组里。  Route::any('/report/countprice', 'report/UserbillController@CountPrice');  Route::any('islogin', 'CommonController@islogin');  Route::any('login', 'CommonController@login');});
