我的nodejs服务器无法检测到新浏览器何时连接（“连接”事件），我也不知道为什么。我将工作范围缩小了几天，并怀疑这是由于在浏览器上实现了pubnub套接字连接所致。

以下是我的server.js

var http    = require('http')
  , connect = require('connect')
  , io      = require('socket.io')
  , fs      = require('fs')
  , uuid    = require('node-uuid')
  , _       = require('lodash');

// pubnub!!! (how to initialize it for use on server)
var pubnub  = require('pubnub').init({
   channel:        "my_channel",
   publish_key:    "pub-key",
   subscribe_key:  "sub-c-key",
   uuid:           "Server",
   origin : 'pubsub.pubnub.com'
});  

pubnub.subscribe({
    channel: 'my_channel',
    callback: function(message) {
      console.log("Message received: ", message);
    },
    message:  'Server ready',
    presence: function(data) {
      console.log("Presense: ", data);
    },
    connect:   publish
});

// various socket.on() events omitted

var app = connect().use(connect.static(__dirname)).use(connect.directory(__dirname));
var server = http.createServer(app);
server.listen(8888);
io = io.listen(server);

io.sockets.on('connection', handleNewPeer);

到达html页面后，从脚本标签运行了doConnect（isBroadcaster）函数。

doConnect函数（在peer.js中）：

var doConnect = function(isBroadcaster) {

  console.log("doConnect");
  // broadcaster or normal peer
  var user;
  if (isBroadcaster) 
    user = "Broadcaster";
  else 
    user = "Viewer";

  (function() {
  var pubnub_setup = {
    channel:       "my_channel",
    publish_key:   "pub-c-key",
    subscribe_key: "sub-c-key",
    user:          user
  };

  // Note removed the var
  socket = io.connect( 'http://pubsub.pubnub.com', pubnub_setup);

 // various socket.on() omitted

 })();

这是以前使用socketIO的情况，并且一直在工作：

var doConnect = function(isBroadcaster) {
  socket = io.connect();
// various socket.on() omitted 
}

我的p2p视频网站是通过在Nodejs + SocketIO服务器上运行的WebRTC实现的。我一直在尝试将pubnub并入其中，并认为这很容易，因为pubnub支持SocketIO（或者至少是客户端？）。真的不认为设置服务器端会如此困难。

对此有什么投入吗？我认为这很简单，我无法将手指放在上面
