代碼已被兌換yii

Question

我從這裏使用Yii和yi的谷歌API yii google api。我想獲取與此API聯繫人列表但這引發錯誤

stdClass的對象（[錯誤] => invalid_grant [ERROR_DESCRIPTION] =>代碼 已經兌現。）

我像這樣使用

public function actionIndex() 
    { 
     $client = Yii::app()->GoogleApis->client; 
     $client -> setAccessType('online'); 
     $client -> setScopes('https://www.google.com/m8/feeds'); 
     $client->authenticate(); 

     if (isset($_GET['code'])) { 
      $auth_code = $_GET["code"]; 
      Yii::app()->session['auth_token']= $auth_code; 
      $this->redirect(array('/addcontacts/searchsuggesions')); 
     } 
     $this->render('index'); 
    } 

public function actionSearchsuggesions() 
    { 
     if(Yii::app()->session['auth_token']) 
     { 
      $auth_code = Yii::app()->session['auth_token']; 
      $max_results = 200; 
      $fields=array(
       'code'=> urlencode($auth_code), 
       'client_id'=> urlencode('**********'), 
       'client_secret'=> urlencode('**********'), 
       'redirect_uri'=> urlencode('http://localhost/addcontacts'), 
       'grant_type'=> urlencode('authorization_code') 
      ); 
      $post = ''; 
      foreach($fields as $key=>$value) 
      { 
       $post .= $key.'='.$value.'&'; 
      } 
      $post = rtrim($post,'&'); 
      $result = $this->curl('https://accounts.google.com/o/oauth2/token',$post); 
      $response = json_decode($result); 
      print_r($response);die; 
     } 
    } 

我不知道我在哪裏錯了。如果有人有線索請告訴我。

我已經解決了這個問題。我只需要使用函數來獲取訪問令牌的功能$client->getAccessToken()。

public function actionIndex() 
    { 
     $client = Yii::app()->GoogleApis->client; 
     $client -> setAccessType('online'); 
     $client -> setScopes('https://www.google.com/m8/feeds'); 
     $client->authenticate(); 

     if (isset($_GET['code'])) { 

      $accesstoken=json_decode($client->getAccessToken()); 
      $accesstoken=$accesstoken->access_token; 
      Yii::app()->session['accesstoken']=$accesstoken; 
      $this->redirect(array('/')); 
     } 
     $this->render('index'); 
    }
