PHP curl偽造IP地址和header資訊代碼執行個體-阿里云

 這篇文章主要介紹了PHP curl偽造IP地址和header資訊代碼執行個體,本文給出伺服器端和用戶端實現代碼,提供偽造功能和伺服器端檢測代碼,需要的朋友可以參考下

  curl雖然功能強大,但是只能偽造$_SERVER["HTTP_X_FORWARDED_FOR"],對於大多數IP地址檢測程式來說,$_SERVER["REMOTE_ADDR"]很難被偽造:

  首先是client.php的代碼

  代碼如下:

  $headers['CLIENT-IP'] = '202.103.229.40';

  $headers['X-FORWARDED-FOR'] = '202.103.229.40';

  $headerArr = array();

  foreach( $headers as $n => $v ) {

  $headerArr[] = $n .':' . $v;

  }

  ob_start();

  $ch = curl_init();

  curl_setopt ($ch, CURLOPT_URL, "http://localhost/curl/server.php");

  curl_setopt ($ch, CURLOPT_HTTPHEADER , $headerArr ); //構造IP

  curl_setopt ($ch, CURLOPT_REFERER, "http://www.163.com/ "); //構造來路

  curl_setopt( $ch, CURLOPT_HEADER, 1);

  curl_exec($ch);

  curl_close ($ch);

  $out = ob_get_contents();

  ob_clean();
 echo $out;

  然後是server.php

  代碼如下:

  function GetIP(){

  if(!emptyempty($_SERVER["HTTP_CLIENT_IP"]))

  $cip = $_SERVER["HTTP_CLIENT_IP"];

  else if(!emptyempty($_SERVER["HTTP_X_FORWARDED_FOR"]))

  $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];

  else if(!emptyempty($_SERVER["REMOTE_ADDR"]))

  $cip = $_SERVER["REMOTE_ADDR"];

  else

  $cip = "無法擷取!";

  return $cip;

  }

  echo "
訪問IP: ".GetIP()."
";

  echo "
訪問來路: ".$_SERVER["HTTP_REFERER"];
