加群链接需要idkey的，该源码自动解析idkey，实现免idkey加群。


例如：你的域名/qqun.php?qun=99968722

代码如下：

<?php
/*免IDKEY加群
*/
error_reporting(0);
function get_curl($url, $post=0, $referer=0, $cookie=0, $header=0, $ua=0, $nobaody=0)
{
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
	if ($post) {
		curl_setopt($ch, CURLOPT_POST, 1);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
	}
	if ($header) {
		curl_setopt($ch, CURLOPT_HEADER, true);
	}
	if ($cookie) {
		curl_setopt($ch, CURLOPT_COOKIE, $cookie);
	}
	if ($referer) {
		curl_setopt($ch, CURLOPT_REFERER, $referer);
	}
	if ($ua) {
		curl_setopt($ch, CURLOPT_USERAGENT, $ua);
	}
	else {
		curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Linux; U; Android 4.0.4; es-mx; HTC_One_X Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0");
	}
	if ($nobaody) {
		curl_setopt($ch, CURLOPT_NOBODY, 1);
	}
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	$ret = curl_exec($ch);
	curl_close($ch);
	return $ret;
}
$qun=isset($_GET['qun'])?$_GET['qun']:'99968722';
$data=get_curl('http://shang.qq.com/wpa/g_wpa_get?guin='.$qun.'&t='.time(),0,'http://qun.qq.com/join.html');
$arr=json_decode($data,true);
$idkey=$arr['result']['data'][0]['key'];
$url='http://shang.qq.com/wpa/qunwpa?idkey='.$idkey;
header("Location:{$url}");
exit;
