Google+ 分享计数错误

Question

我在 google+ 中查找网站的共享计数时遇到问题。我已经完成了 facebook、tweeter 等，但我无法弄清楚如何在 google+ 中进行操作。我已经搜索过这个解决方案，但它只返回 0。

function get_plusones($url) {
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, "https://clients6.google.com/rpc");
  curl_setopt($curl, CURLOPT_POST, 1);
  curl_setopt($curl, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
 $curl_results = curl_exec ($curl);
 curl_close ($curl);
 $json = json_decode($curl_results, true);
 return intval( $json[0]['result']['metadata']['globalCounts']['count'] ); 

}

我做错了什么？有什么解决办法吗？
