无法在Laravel 4中使用Facebook的PHP SDK获取用户个人资料

Question

我是使用Facebook全新PHP 4 SDK的应用程序。我正在尝试使用Facebook登录。我正在使用Laravel 4.但似乎有些不对劲，我无法弄明白。

这是我的控制器代码。

<?php
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;

class FacebookController extends BaseController{
    public function __construct(){
        session_start();
        FacebookSession::setDefaultApplication('xxx','yyy');
    }
    //when the user clicks on the login button he comes to this function
    public function getLogin(){
        $helper = new FacebookRedirectLoginHelper(url('facebook/user'));
        return Redirect::to($helper->getLoginUrl());
    }
    //when the user logs in, he comes to this function
    public function getUser(){
        try{
            $session = new FacebookSession(Session::get('_token'));
            $request = new FacebookRequest($session, 'GET', '/me');
            $response = $request->execute();
            $graphObject = $response->getGraphObject()->asArray();
            dd($graphObject);
        } catch(Exception $e){
            dd($e);
        }

    }
}

这是我得到的错误。

我只是猜测我使用新的Facebook PHP SDK时遇到的问题。 你可以解决的问题是FacebookRedirectLoginHelper中的storeState和loadState方法使用与Laravel Session不同的PHP会话方法。

以下是我为解决该问题所做的工作。你基本上必须创建自己的类并扩展FacebookRedirectLoginHelper

像这样的东西。

<?php namespace Ninjaparade\Fbuser\Repo;

use Session;

class NPFacebookRedirectLoginHelper extends \Facebook\FacebookRedirectLoginHelper
{
  protected function storeState($state)
  {
    Session::put('state', $state);
  }

  protected function loadState()
  {
    return $this->state = Session::get('state');
  }
}

然后您可以在登录方法中执行以下操作。

public function getLogin(){
    $helper = new NPFacebookRedirectLoginHelper(url('facebook/user'));
    return Redirect::to($helper->getLoginUrl());
}
