Google+共享计数错误

Question

我在google+中查找网站的共享数时遇到问题。我已经完成了facebook、推特等，但我不知道如何在google+上完成。我搜索过这个解决方案，但只有它返回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？有什么解决方案吗？

Answer 1

发现解决方案没有将www放在url前面。
