Laravel 5.1社会认证工作不正常

最近我的工作laravel 5.1框架，并试图通过社会认证，使用户登录像Facebook登录.. 我也跟着从YouTube Laravel 5.1 Socialite Authentication Laravel 5.1社会认证工作不正常

本教程，但得到这个异常
InvalidStateException in AbstractProvider.php line 191:

in AbstractProvider.php line 191

在AbstractProvider->用户（）在SocialAuthController.php线61 在SocialAuthController-> github_Callback（）在call_us er_func_array（阵列（对象（SocialAuthController）， 'github_Callback'），阵列（））在ControllerDispatcher.php线Controller.php这样线256 在控制器 - > callAction（ 'github_Callback'，阵列（））164

这里是我的代码

// facebook Sociolite for routing 
Route::get('/auth/facebook', 'Auth\[email protected]'); 
Route::get('callback_facebook', 'Auth\[email protected]'); 

// AuthController 

<?php 

namespace App\Http\Controllers\Auth; 

use Illuminate\Http\Request; 

use App\Http\Requests; 

use App\User; 
use Validator; 
use App\Http\Controllers\Controller; 
use Illuminate\Foundation\Auth\ThrottlesLogins; 
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers; 

use Socialite; 
use Auth; 
use redirect; 


class AuthController extends Controller 
{ 
    class SocialAuthController extends Controller{ 
    // For Facebook 
    public function redirectToProvider(){ 

     return Socialite::driver('facebook')->redirect(); 
    } 
    public function handleProviderCallback(){ 
     $curl = curl_init(); 
     curl_setopt($curl , CURLOPT_SSL_VERIFYPEER, false); 

     $user = Socialite::driver('facebook')->user(); 
     $data = ['name'=>$user->name, 'email'=>$user->email, 'password'=>$user->token]; 
     $userDB = User::where('email',$user->email)->first(); 

     if (!is_null($userDB)){ 
      Auth::login($userDB); 
     } 
     else{ 
      Auth::login($this->create($data)); 
     } 
     return redirect('/pages/profile'); 
    } 
    } 
} 

    config\service.php 
    'facebook' => [ 
     'client_id' => '513845902100524', 
     'client_secret' => '135699237e16cd3a50d2cbfec3a5e58c', 
     'redirect' => 'http://localhost:8000/callback_facebook', 
    ],
