我今天把阿修罗这个名号用了，但是我不是为了冒充谁，

我只是单纯的解析了一下这个二级域名，刚好是字母A开始的：A.xiu.no

function qq_login_get_openid_by_token($token) {
	$get_openid_url = "https://graph.qq.com/oauth2.0/me?access_token=$token";
	$s  = https_get($get_openid_url);
	if(strpos($s, "callback") !== false) {
		$lpos = strpos($s, "(");
		$rpos = strrpos($s, ")");
		$s  = substr($s, $lpos + 1, $rpos - $lpos -1);
	}
	
	$arr = xn_json_decode($s);
	if (isset($arr['error'])) {
		$error = $arr['error'].'<br />'.$arr['error_description'];
		return xn_error(-1, $error);
	}
	
	return $arr['openid'];
}
