方法简介#
这是个类似 Cloudflare 的防 cc 功能，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，面对数以万计的肉鸡，这代码还是无能为力的，所以说做人就要低调，别到处装逼，到时候被打了惨的还是自己，下面分享给需要的同学。
首先建个 cc.php 文件代码如下：
<?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>");}}
WordPress 上传到主题 /template/cc.php ;
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'; ?>
WordPress 调用，主题 /header.php 第一行添加代码：
<?php get\_template\_part( 'template/cc' ); ?>
首次访问网站检测浏览器 cookie 通过才能正常的访问你的网站，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。平时没攻击的时候建议不要开启，影响网站体验。
