备案查询程序这个API接口可以运用到自己网站上面，比如说一个导航的详细页面你加上这段代码也显示出了一个网站的备案信息资料这些内容，这个备案查询API我感觉只对做导航的人有用吧！今天分享给大家，不喜欢的也可以研究下代码！<?php error_reporting(0); $url = $_GET['url']; var_dump(); if(!isset($url)){ echo '参数错误!'; die; }elseif($url==''){ echo '未输入要查询的域名!'; }else{ $str = file_get_contents('http://icp.chinaz.com/'.$url); $sitenames = getSubstr($str, '</a></p>', '>['); preg_match('/<a target="_blank" href=".*?">(.*?)<\/a>/',$str,$name); preg_match('/<p><strong class="fl fwnone">(.*?)<\/strong><\/p>/',$str,$nature); preg_match('/<p><font>(.*?)<\/font><a href="(.*?)" target="_blank" id="checkscreen" class="fz12 pl15">/',$str,$icp); preg_match('/<p>(.*?)<\/p>/',$sitenames,$sitename); preg_match('/<p class="Wzno">(.*?)<\/p>/',$str,$siteindex); $time = getSubstr($str, '审核时间', ' <p class="fz12">'); //echo $time; preg_match('/<p>(.*?)<\/p>/',$time,$time); if(strpos($str,'未备案或备案取消') == 0){ print_r(json_encode(array('name'=>$name[1],'siteindex'=>$siteindex[1],'nature'=>$nature[1],'icp'=>$icp[1],'sitename'=>$sitename[1],'img'=>'http://icp.chinaz.com'.$icp[2],'time'=>$time[1]),320)); }else{ print_r(json_encode(array('code'=> -1,'msg'=>'未查询到备案!'),320)); } } function getSubstr($str, $leftStr, $rightStr){ $left = strpos($str, $leftStr); $right = strpos($str, $rightStr,$left); if($left < 0 or $right < $left) return ''; return substr($str, $left + strlen($leftStr), $right-$left-strlen($leftStr)); } ?>使用方法：把源码保存到beian.php，然后访问“域名/beian.php?url=查询域名”即可。

首先安装 Dockercurl -sSL https://get.docker.com/ | shsystemctl start dockersystemctl enable dockersystemctl enable dockerdocker run -d -p 6688:80 ilemonrain/html5-speedtest:alpine搭建完成打开 http://你VPS的IP:6688 即可如果CentOS 7打不开，需要打开防火墙端口，或者关掉防火墙打开6688端口firewall-cmd --zone=public --add-port=6688/tcp --permanent关闭防火墙systemctl stop firewalld.service systemctl disable firewalld.service 

1、伪造客户端IP地址，伪造访问referer:（一般情况下这就可以访问到数据了）curl_setopt($curl, CURLOPT_HTTPHEADER, ['X-FORWARDED-FOR:110.85.108.185', 'CLIENT-IP:110.85.108.185']); curl_setopt($curl, CURLOPT_REFERER, 'http://4dn.net/test.php');2、如是上面的还是不行，可能是别人抓到了真实IP，这时候我们就使用代{过}{滤}理访问# 详细方式 curl_setopt($curl, CURLOPT_PROXY, 'x.x.x.x'); //代{过}{滤}理服务器地址 curl_setopt($curl, CURLOPT_PROXYPORT, 80); //代{过}{滤}理服务器端口 //curl_setopt($curl, CURLOPT_PROXYUSERPWD, ':''); //http代{过}{滤}理认证帐号，username:password的格式 curl_setopt($curl, CURLOPT_PROXYTYPE, CURLPROXY_HTTP); //使用http代{过}{滤}理模式 # 简写方式 curl_setopt($curl, CURLOPT_PROXY, 'http://x.x.x.x:80');3、还有一种就是用浏览器可以访问，用curl不行。（对方检查了useragent，如果没有就认为是非法来源等验证了）$useragent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 '; $useragent.= '(KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'; curl_setopt($curl, CURLOPT_USERAGENT, $useragent);PHP完整Curl抓取数据函数：/** * 请求接口 * [url=home.php?mod=space&uid=718080]@access[/url] public * [url=home.php?mod=space&uid=952169]@Param[/url] string $url 请求地址 * @param array $data 提交参数 没有get 有post * [url=home.php?mod=space&uid=155549]@Return[/url] bean|array */ public function send($url='') { set_time_limit(0); $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl, CURLOPT_HTTPHEADER, ['X-FORWARDED-FOR:127.0.1.1', 'CLIENT-IP:127.0.1.1']); curl_setopt($curl, CURLOPT_REFERER, 'http://4dn.net/demo.php'); curl_setopt($curl, CURLOPT_PROXY, 'http://127.0.0.1:80'); $useragent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 '; $useragent.= '(KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'; curl_setopt($curl, CURLOPT_USERAGENT, $useragent); if(!empty($data) && is_array($data)){ curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } $html = curl_exec($curl); if($error=curl_errno($curl)){ return false; } curl_close($curl); return $html; }
