修改浏览器指纹之webrtc指纹修改

     因需求需要获取客户端的本机IP，目前比较好的办法是Html5+webrtc获取本机ip

浏览器指纹完整查看：http://www.sdfymj.com/ua.php 另外，个人出一套完整浏览器硬件指纹修改源码

 

附上代码：

  

function findIP(onNewIP) { //  onNewIp - your listener function for new IPs[/font]  var myPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection; //compatibility for firefox and chrome
  var pc = new myPeerConnection({iceServers: []}), // 空的ICE服务器（STUN或者TURN）
    noop = function() {},
    localIPs = {}, //记录有没有被调用到onNewIP这个listener上
    ipRegex = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/g,
    key;
  
  function ipIterate(ip) {
    if (!localIPs[ip]) onNewIP(ip);
    localIPs[ip] = true;
  }
  pc.createDataChannel(""); //create a bogus data channel
  pc.createOffer().then(function(sdp) {
    sdp.sdp.split('\n').forEach(function(line) {
      if (line.indexOf('candidate') < 0) return;
      line.match(ipRegex).forEach(ipIterate);
    });
    pc.setLocalDescription(sdp, noop, noop);
  }); // create offer and set local description
  pc.onicecandidate = function(ice) { //listen for candidate events
    if (!ice || !ice.candidate || !ice.candidate.candidate || !ice.candidate.candidate.match(ipRegex)) return;
    ice.candidate.candidate.match(ipRegex).forEach(ipIterate);
  };
}
  
  
  
var ul = document.createElement('ul');
ul.textContent = 'Your IPs are: '
document.body.appendChild(ul);
  
function addIP(ip) {
  console.log('got ip: ', ip);
  var li = document.createElement('li');
  li.textContent = ip;
  ul.appendChild(li);
}
  
findIP(addIP);
