【问题描述】:
使用rpc方法:
$url = 'http://www.google.com';
$curl = curl_init();
curl_setopt($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);
echo intval( $json[0]['result']['metadata']['globalCounts']['count'] );
还是使用 +1 按钮报废方法?
$url = 'http://www.google.com';
$result = file_get_contents('https://plusone.google.com/_/+1/fastbutton?url='.urlencode($url));
preg_match( '/window\.__SSR = {c: ([\d]+)/', $result, $matches );
echo (isset($matches[0])) ? (int) str_replace('window.__SSR = {c:', '', $matches[0]) : 0;
解释差异或可能的副作用会很棒。
注意:这两种方法都适用于 2014/04/05。
