php curl 伪造IP来源程序实现代码

今天没事做自己写了一个php curl 伪造IP来源程序实例程序，这里可以 伪造IP来源, 伪造域名, 伪造用户信息，有需要了解的朋友可参考。

定义伪造用户浏览器信息HTTP_USER_AGENT

代码如下

复制代码

$binfo =array('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; InfoPath.2; AskTbPTV/5.17.0.25589; Alexa Toolbar)','Mozilla/5.0 (Windows NT 5.1; rv:22.0) Gecko/20100101 Firefox/22.0','Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; Alexa Toolbar)','Mozilla/4.0(compatible; MSIE 6.0; Windows NT 5.1; SV1)',$_SERVER['HTTP_USER_AGENT']); //123.125.68.* //125.90.88.*

定义伪造IP来源段，这里我找的是百度的IP地址

代码如下	复制代码
$cip = '123.125.68.'.mt_rand(0,254); $xip = '125.90.88.'.mt_rand(0,254); $header = array( 'CLIENT-IP:'.$cip, 'X-FORWARDED-FOR:'.$xip, );

利用curl开始向服务器发送伪造信息

代码如下

复制代码

function getimgs( $url,$userinfo,$header) { $ch = curl_init(); $timeout = 5; curl_setopt ($ch, CURLOPT_URL, "$url"); curl_setopt ($ch, CURLOPT_HTTPHEADER, $header); curl_setopt ($ch, CURLOPT_REFERER, "http://www.baidu.com/"); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_USERAGENT, "$userinfo"); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $contents = curl_exec($ch); curl_close($ch); return $contents; }

获取到数据我们再保存

代码如下	复制代码
function saveimgs( $handle ) { $fp = fopen('a.jpg',"w"); fwrite($fp,$handle); unset($fp); unset($handle); }

测试伪造IP实例

代码如下	复制代码
$url ='http://www.bKjia.c0m/img/logo.jpg'; $u = $binfo[mt_rand(0,3)]; saveimgs(getimgs($url,$u,$header));

这样就在你当前目录保存成功了一个文件a.jpg文件，我现可以查看服务器日志是不是我们自定的用户信息呢

看出来了吧，完全正确啊，只是IP地址我怎么没测试出来，这个使用php获取ip地址时会是显示我伪造IP地址了
