Perfectly compatible with major browsers to obtain HTTP_REFERER method summary_javascript skills

Later I checked some relevant information and found that IE cannot get HTTP_REFERER through window.location.href or I really don’t understand IE’s browser. Many browsers run very good things, but it just doesn’t support it. , in the end there is no way but to forge the source HTTP_REFERER method in PHP or use JS to forge it.

The HTTP_REFERER submission that IE can recognize is an event triggered by a click or a request submitted by a Form form. The following is a method summarized based on online information:

<script>
function referURL(url){
var isIe=(document.all)&#63;true:false;
if(isIe) {
var linka = document.createElement(‘a');
linka.href=url;
document.body.appendChild(linka);
linka.click();
}
else window.location = url;
}

var url=”http://www.jb51.net”;
referURL(url);
</script>

This method first uses document.all to determine whether the current browser is IE. If so, it generates a link, and then automatically executes the onclick event. If not, it uses JS to jump. In this way, you can get HTTP_REFERER when processing the page

This method has been tested in IE, Firefox, Safari and Chrome

2. PHP uses curl to forge IP and source HTTP Referrer

referer.php

<&#63;php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://mydomain.com/ip.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //构造IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.jb51.net/ ");  //构造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);

echo $out;

ip.php

<&#63;php
function getClientIp() {
if (!empty($_SERVER["HTTP_CLIENT_IP"]))
$ip = $_SERVER["HTTP_CLIENT_IP"];
else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
else if (!empty($_SERVER["REMOTE_ADDR"]))
$ip = $_SERVER["REMOTE_ADDR"];
else
$ip = "err";
return $ip;
}
echo "IP: " . getClientIp() . "<br>";
echo "referer: " . $_SERVER["HTTP_REFERER"];
