php - Facebook php-sdk v4 获取好友列表

Question

我正在使用新的 facebook php sdk v4，我想检索完整的 friend 列表 代码:

try {

$user_friends = (new FacebookRequest(
  $session, 'GET', '/me/friends'
))->execute()->getGraphObject(GraphUser::className());

echo '<pre>';
print_r($user_friends);

 } catch(FacebookRequestException $e) {

echo "Exception occured, code: " . $e->getCode();
echo " with message: " . $e->getMessage();

} 

但结果是:

Facebook\GraphUser Object
 (
[backingData:protected] => Array
    (
    )
  )

登录网址参数:

$loginUrl = $helper->getLoginUrl(array( 'publish_actions', 'user_friends', 'public_profile' ) );

此功能是否被禁用？还有另一种方法可以获取好友列表吗？

提前谢谢

您只会找到那些使用相同 Facebook 应用程序的 friend 。

\Facebook\FacebookSession::setDefaultApplication('id','secret');

$session = new \Facebook\FacebookSession('access_token');

// Check user's token is valid or not.
$me = (new \Facebook\FacebookRequest(
$session, 'GET', '/me/friends'
))->execute()->getGraphObject(\Facebook\GraphUser::className());

$result = $me->asArray();

// Get user's friends
$friends = $result['data'];

// Converting classes to array
foreach ($friends as $key => $value) {
    $friends[$key] = (array)$value;
}
