【技术分享】最新EMLOG简易防CC攻击代码-3秒5次刷新限制emlog防护计划_咸鱼之王俱乐部科技怎么点亮

安鹿分享EMLOG博客的技术G简简易防CC攻击解决计划
，提供PHP代码通过检测代理IP、分享g防咸鱼之王俱乐部科技怎么点亮监控会谈刷新频率实现防护 。最新咸鱼之王科技点教程攻略

代码设置3秒内超过5次刷新即触发跳转至本地地址并推脱访问，易防咸鱼之王科技点满要多少通过在EMLOG的攻击咸鱼之王科技战士升完升什么module.php中定义防护函数
、header.php中调用函数落成部署。代码咸鱼之王科技推图

EMLOG没有自己的秒次防护措施，可以用这个PHP代码修改成EMLOG的刷新防护措施。

源代码原理如下:

移植到Emlog教程

将下面代码插入在module.php文件内

<span class="pun"><?</span><span class="pln">php
</span><span class="kwd">function</span><span class="pln"> aeink_cc</span><span class="pun">(){</span>

phpfunction aeink_cc(){//代理IP直接退出    empty($_SERVER[HTTP_VIA])orexit(Access Denied);//防止快速刷新    session_start();    $seconds =3;//时间段[秒]    $refresh =5;//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]= $cur_time;}//筹备监控结果if($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header.php文件 前插入

<span class="pun"><?</span><span class="pln">php echo aeink_cc</span><span class="pun">();</span><span class="pun">?></span>
php echo aeink_cc();?>
php echo aeink_cc();?>
