webrtc学习笔记四(获取真实的ip)



<script>
function getIPs(callback){
var ip_dups = {};

//compatibility for firefox and chrome
var RTCPeerConnection = window.RTCPeerConnection
|| window.mozRTCPeerConnection
|| window.webkitRTCPeerConnection;
var mediaConstraints = {
optional: [{RtpDataChannels: true}]
};

//firefox already has a default stun server in about:config
// media.peerconnection.default_iceservers =
// [{"url": "stun:stun.services.mozilla.com"}]
var servers = undefined;

//add same stun server for chrome
if(window.webkitRTCPeerConnection)
servers = {iceServers: [{urls: "stun:stun.services.mozilla.com"}]};

//construct a new RTCPeerConnection
var pc = new RTCPeerConnection(servers, mediaConstraints);

//listen for candidate events
pc.onicecandidate = function(ice){

//skip non-candidate events
if(ice.candidate){

//match just the IP address
var ip_regex = /([0-9]{1,3}(\.[0-9]{1,3}){3})/
var ip_addr = ip_regex.exec(ice.candidate.candidate)[1];

//remove duplicates
if(ip_dups[ip_addr] === undefined)
callback(ip_addr);

ip_dups[ip_addr] = true;
}
};

//create a bogus data channel
pc.createDataChannel("");

//create an offer sdp
pc.createOffer(function(result){

//trigger the stun server request
pc.setLocalDescription(result, function(){});

}, function(){});
}

//Test: Print the IP addresses into the console
getIPs(function(ip){console.log(ip);});
