烈焰架设CDN网站无法获取真实IP的修改方案

将1.php中的方法:getIp()
修改为
function getIp() {
                $ip = $_SERVER['REMOTE_ADDR'];
                   if (isset($_SERVER['HTTP_X_REAL_FORWARDED_FOR']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_REAL_FORWARDED_FOR'])) {
                        $ip = $_SERVER['HTTP_X_REAL_FORWARDED_FOR'];
                }  
                 elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_FORWARDED_FOR'])) {
                        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
                }  
                elseif (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) {
                        $ip = $_SERVER['HTTP_CLIENT_IP'];
                } 
                return $ip;
}
