为什么 Facebook PHP SDK getUser 总是返回 0？打开购物车

Question

我在 OpenCart2.1.x.

中访问 $this->fbconnect->getUser(); 时得到 0 结果

下面是我正在使用的代码：

在 register 控制器中，我正在制作 URL 如下：

if(!$this->customer->isLogged()){
           if(!isset($this->fbconnect)){            
    require_once(DIR_SYSTEM . 'facebook/facebook.php');
    $this->fbconnect = new Facebook(array(
        'appId'  => $this->config->get('facebook_apikey'),
        'secret' => $this->config->get('facebook_apisecret'),
         'redirect_uri'  => $this->url->link('facebook/facebook', '', 'SSL'),
         'cookie' => true,
         'domain'=>'abc.com'
    ));
   }

   $data['facebook_url'] = $this->fbconnect->getLoginUrl(
    array(
        'scope' => 'public_profile, email',
        'redirect_uri'  => $this->url->link('facebook/facebook', '', 'SSL')
    )
   );
}

和 register.tpl 中的 URL 没问题，我被重定向到 FB 登录页面进行身份验证。但是在返回我的网站时登录后，我得到 0 的 getUser() 功能。

catalog/controller/facebook/facebook.php中的Facebook控制器代码如下：

if(!isset($this->fbconnect)){           
    require_once(DIR_SYSTEM . 'facebook/facebook.php');

    $this->fbconnect = new Facebook(array(
        'appId'  => $this->config->get('fbconnect_apikey'),
        'secret' => $this->config->get('fbconnect_apisecret'),
         'redirect_uri' => $this->url->link('facebook/facebook', '', 'SSL'),
    ));
}

$_SERVER_CLEANED = $_SERVER;
$_SERVER = $this->clean_decode($_SERVER);

echo $fbuser = $this->fbconnect->getUser();  **0**

我的应用设置是：

此处:: abc.com 表示我的实际网站 URL 将被替换为此处。

Please do not mark this question as DUPLICATE because i have already searched on SO and everywhere and nothing is working here for me. So, please try to give the solution and that is i am posting question after searching for more than 1 day.

试试这个 ;)

替换

echo $fbuser = $this->fbconnect->getUser();

和

try {
  // Returns a `Facebook\FacebookResponse` object
  $response = $this->fbconnect->get('/me?fields=id,name', '{access-token}');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

$user = $response->getGraphUser();

echo 'Id: ' . $user['id'];
echo 'Name: ' . $user['name'];
