php中fsockopen模仿post与get详解
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 ( "HdhCmsTestphpfensi测试数据" , 80, $errno , $errstr , 30); if (! $fp ) { echo "$errstr ($errno)<br />n" ; } else { $out = "GET / HTTP/1.1rn" ; $out .= "Host: HdhCmsTestexample测试数据rn" ; $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 ; } } ?>查看更多关于php中fsockopen模仿post与get详解 - php高级应用的详细内容...
