伪造ip与来路。
1，curl伪造IP和来路 客户端 client.php
复制代码 代码示例:
<?php
$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 , $headerArr ); //构造IP
curl_setopt ($ch, CURLOPT_REFERER, "http://www.jb200.com/ "); //构造来路
curl_setopt( $ch, CURLOPT_HEADER, 1);
curl_exec($ch);
curl_close ($ch);
$out = ob_get_contents();
ob_clean();
echo $out;
?>
2，curl伪造IP和来路 服务端 server.php
复制代码 代码示例:
<?php
function GetIP(){
if(!empty($_SERVER["HTTP_CLIENT_IP"]))
$cip = $_SERVER["HTTP_CLIENT_IP"];
else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
else if(!empty($_SERVER["REMOTE_ADDR"]))
$cip = $_SERVER["REMOTE_ADDR"];
else
$cip = "无法获取！";
return $cip;
}
echo "<BR>访问IP: ".GetIP()."<br>";
echo "<BR>访问来路: ".$_SERVER["HTTP_REFERER"];
?>
补充：$_SERVER['REMOTE_ADDR']无法伪造。
