获取用户真实IP原理:
客官看完了业界常用的获取用户真实IP方法后,发现有个共同规律,主要核心就是
HTTP_CLIENT_IP
HTTP_X_FORWARDED_FOR
REMOTE_ADDR
不同的演变,只是代码兼容性罢了!
如何模拟用户真实IP?
问:如果可以伪造模拟HTTP_CLIENT_IP,伪造模拟HTTP_X_FORWARDED_FOR,伪造模拟REMOTE_ADDR,不就可以达到追踪不到用户真实IP的目的了么?
答:楼上理解完全正确!如果做到这样完全可以通杀99%的获取用户真实IP,以用户IP为标识的系统!
支招【LET采集技巧】(curl、socket、fsocketopen、stream_socket_client):
如何模拟HTTP_CLIENT_IP?HTTP_CLIENT_IP可以模拟么?伪装HTTP_CLIENT_IP!
curl_setopt($curl, CURLOPT_HTTPHEADER, array (
'Client_Ip: '.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255),
));//优点:伪造成本低,通杀90%系统
如何模拟HTTP_X_FORWARDED_FOR?HTTP_X_FORWARDED_FOR可以模拟么?伪装HTTP_X_FORWARDED_FOR!
curl_setopt($curl, CURLOPT_HTTPHEADER, array (
'X-Forwarded-For: '.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255),
));//优点:伪造成本低,通杀90%系统
如何模拟REMOTE_ADDR?REMOTE_ADDR可以模拟么?伪装REMOTE_ADDR!
curl_setopt($curl, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt($curl, CURLOPT_PROXY, '1.1.1.1:8080');//自行百度获得普匿代理IP即可,高匿代理IP更佳!
//优点:通杀100%系统
