NodeJS and SocketIO on Server - javascript

I have a problem with my NodeJS and SocketIO setup on my server,
I want to access the HTTP Port by doing
var socket = io.connect("http://domain.com:8070");
Sadly this returns ERR_CONNECTION_TIMED_OUT
Here is my Server:
var app = require('http').createServer(handler)
, io = require('socket.io').listen(app, { log: false })
, fs = require('fs');
var mysocket = 0;
var socket = 0;
app.listen(8070);
function handler (req, res) {
fs.readFile(__dirname + '/app/tpl/skins/habbo/client.php',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
console.log('Client successfully connected');
mysocket = socket;
});
//udp server on 41181
var dgram = require("dgram");
var server = dgram.createSocket("udp4");
server.on("message", function (msg, rinfo) {
console.log("Packet recieved from server: " + msg);
if (mysocket != 0) {
mysocket.emit('field', "" + msg);
mysocket.broadcast.emit('field', "" + msg);
}
});
server.on("listening", function () {
var address = server.address();
console.log("udp server listening " + address.address + ":" + address.port);
});
server.bind(41181);
and my Client:
<script src="http://domain.com:8070/socket.io/socket.io.js"></script>
<script type="text/javascript">
var socket = io.connect(http://domain.com:8070);
socket.on("hello", function(l){
var k = l.split(/,/);
switch(k){
case "testing":
{
window.alert('lol');
return;
}
}
});
</script>
Any ideas on how I can get it to work on http://domain.com:8070? Thanks.


It looks like your socket is not listening on port 8070.
Untested, but worth a try :
var io = require('socket.io').listen(app.listen(8070), {log: false});
You can also remove the URL from your client (although it shoudn't change anything) :
var socket = io.connect();
Edit :
You should also wrap the address in quotes :
var socket = io.connect("http://domain.com:8070");

Can not read property '/' of undefined

I started studying node.js. I ask you questions while studying. when I run my code(server) and connect to localhost, It doesn't work properly.
This is error:
This is my code:
index.js
var server = require('./server');
var router = require('./router');
var requestHandlers = require('./requestHandlers');
var handle = {};
handle['/'] = requestHandlers.view;
handle['/view'] = requestHandlers.view;
handle['/create'] = requestHandlers.create;
server.start(router.route, requestHandlers.handle);
server.js
var http = require('http');
var url = require('url');
function start(route, handle) {
function onRequest(request, response) {
var pathname = url.parse(request.url).pathname;
console.log('\nrequest for ' + pathname + ' received.');
response.writeHead(200, {'Content-Type' : 'text/plain'});
// route(handle, pathname); // injected function call
var content = route(handle, pathname);
response.write(content);
response.end();
}
http.createServer(onRequest).listen(8000);
console.log('server has started.');
}
exports.start = start;
router.js
function route(handle, pathname) {
console.log('about to route a request for ' + pathname);
if (typeof handle[pathname] === 'function') {
return handle[pathname]();
} else {
console.log('no request handler found for ' + pathname);
return "404 Not found";
}
}
exports.route = route;
requestHandlers.js
function view(response) {
console.log('request handler called --> view');
return "Hello View";
}
function create(response) {
console.log('request handler called --> create');
return "Hello Create";
}
exports.view = view;
exports.create = create;

In index.js, you're passing requestHandlers.handle, which doesn't exist, rather than the handle object that you've created.
var server = require('./server');
var router = require('./router');
var requestHandlers = require('./requestHandlers');
var handle = {};
handle['/'] = requestHandlers.view;
handle['/view'] = requestHandlers.view;
handle['/create'] = requestHandlers.create;
// server.start(router.route, requestHandlers.handle);
server.start(router.route, handle);

How to access/save the session data on the authorization event in Socket.io/express-sessions?

I setup a websocket using Socket.io and express 4 framework on node.js server.
I am trying to implement authorization step for my users when using my websocket.
When a user connects, a token is passed as a query value to the server. At the server level, I query a database for a session that match the passed token. If a session is found, I do few other check to ensure that the token is not hijacked.
Problem
The session data seems to be cleared on every page reload. Or the server is failing to link the sessionId to the user who created it so everytime it generates a new session.
I am puzzled on how to access the session variables "if they are set."
My Code's Problem
When a user reload his/her page/client, the session data will become undefined on the new request. The session is good until the page is refreshed which is my problem. I need to be able to keep the session active even after the user refresh their page.
Questions
How can ensure that the session data are not cleared on every page refresh?
Here is my authorization code
io.set('authorization', function (handshakeData, accept) {
var session = handshakeData.session || {};
//This is always undefined!
console.log('Session Data:' + session.icwsSessionId);
//var cookies = handshakeData.headers.cookie;
var token = handshakeData._query.tokenId || '';
//console.log('Token: ' + token);
if(!token){
console.log('Log: token was not found');
return accept('Token was found.', false);
}
//allow any user that is authorized
if(session && session.autherized && token == session.token){
console.log('Log: you are good to go');
return accept('You are good to go', true);
}
//if the client changed their token "client logged out"
//terminate the open session before opening a new one
if (session.autherized && token != session.token){
var icwsConnection = new icwsConn(icwsRequest);
icwsRequest.setConnection(session.icwsServer, session.icwsPort);
icwsRequest.setIcwsHeaders(session.icwsSessionId, session.icwsToken);

Which version of socket.io are you using?
express-socket.io-session works with socket.io 1.x
I see you're calling io.set() which is deprecated on socket.io 1.x
For more on this, take a look at http://socket.io/docs/migrating-from-0-9/ under the title Authentication differences.
There, it's stated that
The old io.set() and io.get() methods are deprecated and only
supported for backwards compatibility."
Could this be related to your issue ?
When you install the express-socket.io-session package, there's an example directory inside the package. It may come in handy to test against a working example for this module.

Here is a working example of how you can share sessions between express and socket.io, even when they are not on the same domain.
(You can find a slightly different git repository with a running example here https://github.com/dievardump/express-socket-auth )
I simply use express-session, I don't see why using another middleware, since it works perfectly with socket.io
Since I do not have redis accessible, I used require('session-file-store') for the shared sessions.
Problem
Problem comes from the cross-domain policy which won't let you share the connect.sid Cookie value.
A workaround is :
serve non-httpOnly session cookies from the host (here for me server.dev). [express.js line 16]
read via JavaScript and send the connect.sid value as a sessionId parameter when connection to socket.io [client.js line 26:30]
when handshaking adding the value of connect.sid=socket.handshake.query.sessionId to the socket.handshake.headers.cookie before reading the handshake with the session middleware [socket.js line 32:37]
Architecture
Here followed :
server.js which require
express.js : Create express server accessed on my computer via http://server.dev:3000
serve HTML
create Sessions when loading page
socket.js : Create Socket.io server accessed on my computer via http://socket.dev:8000
client.js
served on http://server.dev:3000
connect to socket server on http://socket.dev:8000
Tests
Steps to test I used here :
Client open the page
If the cookie key connect.sid is not set
Client tries to connect to Socket.io : Connection error : [Not authenticated]
Client calls /authenticate
session is generated
Client tries to connect to Socket.io with value of connect.sid as sessionId parameter : Connection sucessfull
If cookie connect.sid is set
Client tries to connect to Socket.io with value of connect.sid as sessionId parameter : Connection sucessfull

var numUsers = 0;
io.sockets.on('connection', function (socket) {
var addedUser = false;
var address = socket.handshake.address;
console.log("New connection from " + address);
}

That's an IPv4-mapped IPv6 address. I suppose the easiest way to extract the IPv4 portion would be to do something like:
// ...
var idx = address.lastIndexOf(':');
if (~idx && ~address.indexOf('.'))
address = address.slice(idx + 1);

Only Update Specific Users Socket IO and Node JS

I am trying to learn node JS and am currently attempting to extend this article.
http://www.gianlucaguarini.com/blog/push-notification-server-streaming-on-a-mysql-database/
I am having major issue because I am getting multiple updates in the SQL query.
I only want to send one socket update.
This issue is in the transactions loop I get multiple socket updates.
I have been struggling with this for over a month and can't seem to figure it out on my own (or with google searches)
Can someone please tell me how I can make this work so I only get one socket update per client.
What I would like to happen is when there is a change in one of the transactions that the two parties (buyer and seller) are the only ones that get the socket update.
How can I make this work? It is so close to what I want it do but I can't get over this last challenge.
Please help.
Thank you in advance.

i dont start my server because of syntax error on line 79 , but i only have 78 lines .
syntax error unexpected end of input : }); , and can anyone tell me if this is the right way to connect between the mongo and the node web server .

When you call db.once("open", function () { you never close that paren and brace.
I think you want a }); after the testJob declaration. That should also be }) and not )}.
