服务端：

var http = require("http");
var util = require("util");
var fs = require("fs");
var path = require("path");

var express = require("express");
var io = require("socket.io");
var SessionSockets = require('session.socket.io');

var secret = "my secret",key = "connect.id";

var cookieParser = express.cookieParser(secret);
var sessionStore = new express.session.MemoryStore({
	reapInterval:20*60*1000	
});

var app = express();
app.use(cookieParser);
app.use(express.bodyParser());
app.use(express.session({secret: secret,store : sessionStore, key:key }));
app.use(app.router);
app.use(express.methodOverride());
app.get("/:uid",function(req,res){
	var session = req.session;
	var uid = req.param("uid");
	console.log("uid:",uid);
	session.uid = uid;
	process.nextTick(function(){
		session.save();
	});
	fs.readFile(path.join(__dirname,"socket.html"),"utf8",function(err,data){
		if (err) {
			res.end(err);
		}else{
			res.end(data);
		}
	});
});
var server = http.createServer(app);
var socket = io.listen(server);
var sessionSockets = new SessionSockets(socket, sessionStore, cookieParser,key);
sessionSockets.on("connection",function(err,client,session){
	console.log("current session : %s",util.inspect(session));
});

server.listen(3000);
