这是用于给网站添加一个防 cc 功能脚本,利用的是五秒盾的原理,经过检测得到 cookie 的浏览器才能正常的访问你的网站了,当然了,面对大量的请求还是一样得死,这代码还是无能为力的,所以说还是得低调行事,搜索引擎蜘蛛已经过滤,不影响收录,还有未加上的可以自己补充。

首先建个 cc.php 文件代码如下:

1、代码传到网站目录

<?php
define('SYSTEM_ROOT', dirname(preg_replace('@\\(.*\\(.*$@', '', preg_replace('@\\(.*\\(.*$@', '', 
__FILE__))) . '/');
session_start();
date_default_timezone_set('Asia/Shanghai');
header('Content-Type: text/html; charset=UTF-8');
function getspider($useragent=''){
   if(CC_Defender==2)return false;
   if(!$useragent){$useragent = $_SERVER['HTTP_USER_AGENT'];}
$useragent=strtolower($useragent);
   if (strpos($useragent, 'baiduspider') !== false){return 'baiduspider';}
   if (strpos($useragent, 'googlebot') !== false){return 'googlebot';}
   if (strpos($useragent, 'soso') !== false){return 'soso';}
   if (strpos($useragent, 'bing') !== false){return 'bing';}
   if (strpos($useragent, 'yahoo') !== false){return 'yahoo';}
   if (strpos($useragent, 'sohu-search') !== false){return 'Sohubot';}
   if (strpos($useragent, 'sogou') !== false){return 'sogou';}
   if (strpos($useragent, 'youdaobot') !== false){return 'YoudaoBot';}
   if (strpos($useragent, 'yodaobot') !== false){return 'YodaoBot';}
   if (strpos($useragent, 'robozilla') !== false){return 'Robozilla';}
   if (strpos($useragent, 'msnbot') !== false){return 'msnbot';}
   if (strpos($useragent, 'lycos') !== false){return 'Lycos';}
   if (strpos($useragent, 'ia_archiver') !== false || strpos($useragent, 'iaarchiver') !== 
false){return 'alexa';}
   if (strpos($useragent, 'archive.org_bot') !== false){return 'Archive';}
   if (strpos($useragent, 'robozilla') !== false){return 'Robozilla';}
   if (strpos($useragent, 'sitebot') !== false){return 'SiteBot';}
   if (strpos($useragent, 'mj12bot') !== false){return 'MJ12bot';}
   if (strpos($useragent, 'gosospider') !== false){return 'gosospider';}
   if (strpos($useragent, 'gigabot') !== false){return 'Gigabot';}
   if (strpos($useragent, 'yrspider') !== false){return 'YRSpider';}
   if (strpos($useragent, 'gigabot') !== false){return 'Gigabot';}
   if (strpos($useragent, 'jikespider') !== false){return 'jikespider';}
   if (strpos($useragent, 'addsugarspiderbot') !== false){return 'AddSugarSpiderBot';/*非常少*/}
   if (strpos($useragent, 'testspider') !== false){return 'TestSpider';}
   if (strpos($useragent, 'etaospider') !== false){return 'EtaoSpider';}
   if (strpos($useragent, 'wangidspider') !== false){return 'WangIDSpider';}
   if (strpos($useragent, 'foxspider') !== false){return 'FoxSpider';}
   if (strpos($useragent, 'docomo') !== false){return 'DoCoMo';}
   if (strpos($useragent, 'yandexbot') !== false){return 'YandexBot';}
   if (strpos($useragent, 'ezooms') !== false){return 'Ezooms';/*个人*/}
   if (strpos($useragent, 'sinaweibobot') !== false){return 'SinaWeiboBot';}
   if (strpos($useragent, 'catchbot') !== false){return 'CatchBot';}
   if (strpos($useragent, 'surveybot') !== false){return 'SurveyBot';}
   if (strpos($useragent, 'dotbot') !== false){return 'DotBot';}
   if (strpos($useragent, 'purebot') !== false){return 'Purebot';}
   if (strpos($useragent, 'ccbot') !== false){return 'CCBot';}
   if (strpos($useragent, 'mlbot') !== false){return 'MLBot';}
   if (strpos($useragent, 'adsbot-google') !== false){return 'AdsBot-Google';}
   if (strpos($useragent, 'ahrefsbot') !== false){return 'AhrefsBot';}
   if (strpos($useragent, 'spbot') !== false){return 'spbot';}
   if (strpos($useragent, 'augustbot') !== false){return 'AugustBot';}
   return false;
  }

 if($_GET['rand'] && $_SESSION['rand_session']!=$_GET['rand']){
   @header('Content-Type: text/html; charset=UTF-8');
  exit('<b>浏览器不支持 COOKIE 或者不正常访问!</b>');
 }
 if(!$_SESSION['rand_session'] && $nosecu!=true){
    if(!getspider()){
       $rand_session=md5(uniqid().rand(1,1000));
   $_SESSION['rand_session']=$rand_session;
       exit("<!DOCTYPE HTML>
       <html>
       <head>
       <meta charset=\"UTF-8\"/>
       <meta name=\"viewport\" content=\"width=device-width, initial-scale=1, maximum-scale=1\" 
/>

       <title>安全检查中...</title>
    <script> var i = 5;
 var intervalid;
 intervalid = setInterval(\"fun()\", 1000);
function fun() {
if (i == 0) {
window.location.href = \"?{$_SERVER['QUERY_STRING']}&rand={$rand_session}\";
clearInterval(intervalid);
}
document.getElementById(\"mes\").innerHTML = i;
i--;
}
</script>
<style>
   html, body {width: 100%; height: 100%; margin: 0; padding: 0;}
   body {background-color: #ffffff; font-family: Helvetica, Arial, sans-serif; font-size: 100%;}
   h1 {font-size: 1.5em; color: #404040; text-align: center;}
   p {font-size: 1em; color: #404040; text-align: center; margin: 10px 0 0 0;}
   #spinner {margin: 0 auto 30px auto; display: block;}
   .attribution {margin-top: 20px;}
 </style>
 </head>
<body>
 <table width=\"100%\" height=\"100%\" cellpadding=\"20\">
   <tr>
     <td align=\"center\" valign=\"middle\">
   <noscript><h2>请打开浏览器的 javascript,然后刷新浏览器</h2></noscript>
 <h1><span data-translate=\"checking_browser\">浏览器安全检查中...</span></h1>
   <p data-translate=\"process_is_automatic\"></p>
   <p data-translate=\"allow_5_secs\">还剩 <span id=\"mes\">5</span> 秒</p>
 </div>
</div>
 </td>
   </tr>
</table></body></html>");}}

2、调用代码 PHP 通用调用,在头部或主要文件内文件加入:

<?php include 'cc.php'; ?>
