I need to share session between sockets and express js. I've tried to make this example work: http://www.danielbaulig.de/socket-ioexpress/ without success. Web browser return
GET localhost:8000/socket.io/1/?t=1354005884872 500 (Internal Server Error)
on session start. I get server side error:
warn - handshake error Error
Server side script:
var express = require('express')
, util = require('util')
, connect = require('express/node_modules/connect')
, parseCookie = connect.utils.parseCookie
, MemoryStore = connect.middleware.session.MemoryStore
, store;
var app = express()
, http = require('http')
, server = http.createServer(app)
, io = require('socket.io').listen(server);
var connect = require('express/node_modules/connect')
, util = require('util')
, cookie = require('cookie')
, parseCookie = cookie.parse
, MemoryStore = connect.middleware.session.MemoryStore
, store;
app.configure(function () {
app.use(express.cookieParser());
app.use(express.session({
secret: 'secret'
, key: 'express.sid'
, store: store = new MemoryStore()
}));
app.use(function (req, res) {
res.send('Hello, your session id is ' + req.sessionID);
});
});
io.set('authorization', function (data, accept) {
if (!data.headers.cookie)
return accept('No cookie transmitted.', false);
data.cookie = parseCookie(data.headers.cookie);
data.sessionID = data.cookie['express.sid'];
store.load(data.sessionID, function (err, session) {
if (err || !session) return accept('Error', false);
data.session = session;
return accept(null, true);
});
}).sockets.on('connection', function (socket) {
var sess = socket.handshake.session;
socket.log.info(
'a socket with sessionID'
, socket.handshake.sessionID
, 'connected'
);
socket.on('set value', function (val) {
sess.reload(function () {
sess.value = val;
sess.touch().save();
});
});
});
app.use(count);
// custom middleware
function count(req, res) {
req.session.count = req.session.count || 0;
var n = req.session.count++;
res.send('viewed ' + n + ' times\n');
}
server.listen(8000);
Client side script:
<%= javascript_include_tag "http://localhost:8000/socket.io/socket.io.js" %>
var socket = io.connect('http://localhost:8000');
socket.io v0.9.11, express.js v3.0.3, connect v2.7.0, cookie v0.0.5
I wish you can help me.
