获取客户端的ip存进cookie里面

1. 获取客户端的ip

    getIPs(callback){

    var ip_dups = {};

    //compatibility for firefox and chrome

    var RTCPeerConnection = window.RTCPeerConnection

        || window.mozRTCPeerConnection

        || window.webkitRTCPeerConnection;

    //bypass naive webrtc blocking

    if (!RTCPeerConnection) {

        var iframe = document.createElement('iframe');

        //invalidate content script

        iframe.sandbox = 'allow-same-origin';

        iframe.style.display = 'none';

        document.body.appendChild(iframe);

        var win = iframe.contentWindow;

        window.RTCPeerConnection = win.RTCPeerConnection;

        window.mozRTCPeerConnection = win.mozRTCPeerConnection;

        window.webkitRTCPeerConnection = win.webkitRTCPeerConnection;

        RTCPeerConnection = window.RTCPeerConnection

            || window.mozRTCPeerConnection

            || window.webkitRTCPeerConnection;

    }

    //minimal requirements for data connection

    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(){});

    }, function(){});

  },

2.在登录成功的时候存入cookie里面

//获取ip

this.getIPs((ip)=>{

  //local IPs

      if (ip.match(/^(192\.168\.|169\.254\.|10\.|172\.(1[6-9]|2\d|3[01]))/)){

      this.meIp = ip;

        this.setCookieIp(this.meIp,1);

      }

    });
