在php中fsockopen函数可以模仿用户去访问一些网站并且还可以带一些常用的信息,如果浏览器,IP,post,get 等等数据,下面我分别一来给大家介绍介绍. 如果你要使用fsockopen函数我们必须在php.ini中把allow_url_fopen = On 设置为开启状态. 例,fsockopen() Example,代码如下: <?php $fp = fsockopen("www.Cuoxin.com", 80, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />n"; } else { $out = "GET / HTTP/1.1rn"; $out .= "Host: www.example.comrn"; $out .= "Connection: Closernrn"; fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); } ?> 伪造post,POST HTTP请求(URL)并获取返回值,代码如下: <?php $srv_ip = '192.168.1.5';//你的目标服务地址. $srv_port = 80;//端口 $url = 'http://localhost/fsock.php'; //接收你post的URL具体地址 $fp = ''; $errno = 0;//错误处理 $errstr = '';//错误处理 $timeout = 10;//多久没有连上就中断 $post_str = "username=demo&password=hahaha";//要提交的内容. //打开网络的 Socket 链接。 $fp = fsockopen($srv_ip,$srv_port,$errno,$errstr,$timeout); if (!$fp){ echo('fp fail'); } $content_length = strlen($post_str); $post_header = "POST $url HTTP/1.1rn"; $post_header .= "Content-Type: application/x-www-form-urlencodedrn"; $post_header .= "User-Agent: MSIErn"; $post_header .= "Host: ".$srv_ip."rn"; $post_header .= "Content-Length: ".$content_length."rn"; $post_header .= "Connection: closernrn"; $post_header .= $post_str."rnrn"; fwrite($fp,$post_header); $inheader = 1; while(!feof($fp)){//测试文件指针是否到了文件结束的位置 $line = fgets($fp,1024); //去掉请求包的头信息 if ($inheader && ($line == "n" || $line == "rn")) { $inheader = 0; } if ($inheader == 0) { echo $line; } } fclose($fp); unset ($line); ?> 简要说明:代码第二行是你的IP地址或域名,第四行是你要POST的页面的具体地址,本例用的是fsock.php,fsock.php内容如下: <?php echo "username:".$_POST['username']."<br/>"; echo "password:".$_POST['password']; ?> //结果为: username:demo password:hahaha 伪造get,同时伪造post,get方法,代码如下: <?php //fsocket模拟post提交 $purl = "http://localhost/netphp/test2.php?uu=rrrrrrrrrrrr"; print_r(parse_url($url)); sock_post($purl,"uu=55555555555555555"); //fsocket模拟get提交 function sock_get($url, $query) { $info = parse_url($url); $fp = fsockopen($info["host"], 80, $errno, $errstr, 3); $head = "GET ".$info['path']."?".$info["query"]." HTTP/1.0rn"; $head .= "Host: ".$info['host']."rn"; $head .= "rn"; $write = fputs($fp, $head); while (!feof($fp)) { $line = fread($fp,4096); echo $line; } } sock_post($purl,"uu=rrrrrrrrrrrrrrrr"); function sock_post($url, $query) { $info = parse_url($url); $fp = fsockopen($info["host"], 80, $errno, $errstr, 3); $head = "POST ".$info['path']."?".$info["query"]." HTTP/1.0rn"; $head .= "Host: ".$info['host']."rn"; $head .= "Referer: http://".$info['host'].$info['path']."rn"; $head .= "Content-type: application/x-www-form-urlencodedrn"; $head .= "Content-Length: ".strlen(trim($query))."rn"; $head .= "rn"; $head .= trim($query); $write = fputs($fp, $head); while (!feof($fp)) { $line = fread($fp,4096); echo $line; } } ?> (编辑:武汉站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
