EMLOG -最新防CC攻击代码加强版

将下面代码插入在module.php文件内：

代码一:

<?php
function maple\_cc(){
       session\_start();
$timestampcc = time();
$cc\_nowtime = $timestampcc;
if(isset($\_SESSION\['cc\_lasttime'\])){$cc\_lasttime = $\_SESSION\['cc\_lasttime'\];$cc\_times = $\_SESSION\['cc\_times'\]+1;$\_SESSION\['cc\_times'\] = $cc\_times;
}else{$cc\_lasttime = $cc\_nowtime;$cc\_times = 1;$\_SESSION\['cc\_times'\] = $cc\_times;$\_SESSION\['cc\_lasttime'\] = $cc\_lasttime;} 
if(($cc\_nowtime-$cc\_lasttime)<60){if($cc\_times>=3){header(sprintf('Location:%s', 'http://127.0.0.1'));exit;}//60秒内刷新3次以上可能为cc攻击
}else{$cc\_times = 0;$\_SESSION\['cc\_lasttime'\] = $cc\_nowtime;$\_SESSION\['cc\_times'\] = $cc\_times;}
}
?>

代码二:

<?php
function maple\_cc(){
        //代理IP直接退出
        empty($\_SERVER\['HTTP\_VIA'\]) or exit('Access Denied');
        //防止快速刷新
        session\_start();
        $seconds = '60'; //时间段\[秒\]
        $refresh = '3'; //刷新次数
        //设置监控变量
        $cur\_time = time();
        if(isset($\_SESSION\['last\_time'\])){
                $\_SESSION\['refresh\_times'\] += 1;
        }else{
                $\_SESSION\['refresh\_times'\] = 1;
                $\_SESSION\['last\_time'\] = $cur\_time;
        }
        //处理监控结果
        if($cur\_time - $\_SESSION\['last\_time'\] < $seconds){
                if($\_SESSION\['refresh\_times'\] >= $refresh){
                        //跳转至攻击者服务器地址
                        header(sprintf('Location:%s', 'http://127.0.0.1'));
                        exit('Access Denied');
                }
        }else{
                $\_SESSION\['refresh\_times'\] = 0;
                $\_SESSION\['last\_time'\] = $cur\_time;
        }
}
?>

然后在head.php文件的require\_once View::getView('module');后面插入echo maple\_cc();
