I am making a chat for customers of a web page, with express.js, and socket.io, and I'm trying to manage sessions with express-session, my problem is, how do I read the session values on the socket.
Here's part of my code.
Thanks for the help :)
var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var bodyParser = require('body-parser');
var session = require('express-session');
var shortid = require('shortid');
app.use(express.static('public'));
app.use( session({
secret: 'dont move',
resave: true,
saveUninitialized: true
})
);
app.use( bodyParser.urlencoded({ extended: true }) );
app.post('/chat', function(req, res){
var sess = req.session;
sess.ssid = shortid.generate();
res.render('chat', { name: "name" });
});
io.on('connection', function(socket){
socket.on('chat message', function( data ){
if( data.msg.trim() != '' ){
console.log('message: ' + data.msg);
//Here I want to read the ssid session var, so I can manage many chats at the same time
}
});
socket.on('disconnect', function(){
console.log('Hey, someone disconected!');
});
});
http.listen(3000, function(){
console.log('listening on *:3000');
});
You can configure socket authorization
var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var bodyParser = require('body-parser');
var session = require('express-session');
var shortid = require('shortid');
app.use(express.static('public'));
app.use( session({
secret: 'dont move',
resave: true,
saveUninitialized: true
})
);
app.use( bodyParser.urlencoded({ extended: true }) );
app.post('/chat', function(req, res){
var sess = req.session;
sess.ssid = shortid.generate();
res.render('chat', { name: "name" });
});
var util = require('util';
var connect = require('connect');
var parseSignedCookie = connect.utils.parseSignedCookie;
io.configure(function () {
io.set('authorization', function (data, callback) {
if(data.headers.cookie) {
data.cookie = cookie.parse(data.headers.cookie);
data.sessionId = parseSignedCookie(data.cookie['ssid'], 'dont move');
}
callback(null, true);
});
io.on('connection', function(socket) {
var sessionId = socket.handshake.sessionId;
socket.on('chat message', function( data ){
if( data.msg.trim() != '' ){
console.log('message: ' + data.msg);
// NOW YOU CAN USE `sessionId`
}
});
socket.on('disconnect', function(){
console.log('Hey, someone disconected!');
});
});
});
http.listen(3000, function(){
console.log('listening on *:3000');
});

I need to do sessions with nodejs, but using socket.io ..
I have this functional code, which works with the get method
var express = require('express')
var session = require('express-session')
var app = express()
app.use(session({
secret: 'keyboard cat',
resave: true,
saveUninitialized: true,
cookie: { maxAge: 28800000 }}))
app.get('/', function(req, res, next) {
var sess = req.session
if (sess.views) {
sess.views++
res.setHeader('Content-Type', 'text/html')
res.write('<p>views: ' + sess.views + '</p>')
res.end()
console.log(sess.views)
} else {
sess.views = 1
res.end('welcome to the session demo. refresh!')
console.log(sess.views)
}
})
console.log('Server iniciado y operando!')
app.listen(3000)
But I need sessions using this method
var express = require('express');
var app = express();
var server = require('http').Server(app);
var io = require('socket.io')(server);
app.use(express.static('client'));
var messages = [{
id: 1,
text: 'Bienvenido al chat privado de Socket y Node de Luis Zurita',
nickname: 'BELICOFSA dice:'
}];
io.on('connection', function(socket){
console.log("El equipo con IP: "+socket.handshake.address+" se ha conectado...");
socket.emit('caja-chat', messages);
socket.on('add-message', function(data){
messages.push(data);
io.sockets.emit('caja-chat', messages);
});
});
server.listen(3000, function(){
console.log('Servidor esta Funcionando en http://localhost:6677');
});
What I have done best is this, but it does not work as code 1
can you help me?
var express = require('express')
var app = express()
var server = require('http').Server(app);
var ios = require('socket.io-express-session');
var io = require('socket.io')(server);
var Session = require('express-session');
var session = Session({
secret: 'sdfgf',
resave: true,
saveUninitialized: true,
cookie: { maxAge: 100000 }
});
var messages = [{
id: 1,
text: 'Bienvenido al chat privado de Socket y Node de Luis Zurita',
nickname: 'BELICOFSA dice:'
}];
server.listen(3000, function(){
console.log('Servidor esta Funcionando en http://localhost:6677');
});
io.use(ios(session));
app.use(express.static('client'));
io.on('connection', function(socket){
socket.handshake.session.save;
var sess = socket.handshake.session;
if (sess.views) {
sess.views++
} else {
sess.views = 1
}
console.log(sess);
socket.emit('caja-chat', messages);
socket.on('add-message', function(data){
messages.push(data);
io.sockets.emit('caja-chat', messages);
});
});
I have a nodejs app running on Heroku. Here is the server.js file
var express = require('express')
, cors = require('cors')
, app = express();
var http = require('http').Server(app);
var io = require("socket.io").listen(http);
app.use(cors());
require('./modules/routes.js')(app,io);
app.set('port', process.env.PORT || 5000);
app.listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'));
});
Here is my routes.js
"use strict";
const bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
var session = require('express-session');
var time = require('express-timestamp');
var Promise = require('promise');
var momentjs = require('moment');
var _ = require('lodash');
var method = routes.prototype;
function routes(app, io) {
app.use(time.init);
app.use(cookieParser());
app.use(session({ secret: 'asdo8rter65edfgfd53wet34634632y4bluaq', resave: true, saveUninitialized: true }));
app.all('/', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With");
next();
});
app.use(bodyParser.json());
app.post('/testHeroku', function(req, res) {
console.log(req);
res.write(JSON.stringify({
process: "success"
}));
res.end();
});
}
method.getroutes = function() {
return this;
}
module.exports = routes;
I'm trying to access /testHeroku from an ionic app running in android emulator.
Ionic code:
vm.testHeroku = function(){
console.log('testing heroku');
var testdata = {
url: config.baseURL + 'testHeroku',
dataServer: {
serverTaskRequest: 'getUADSF'
}
}
runajax.runajax_function(testdata, function (testdataResponse) {
if (testdataResponse.process == 'success') {
alert(testdataResponse.process);
}
});
};
Here goes my config.baseURL = abcd-1234.herokuapp.com (This is example for the heroku app url)
I don't receive any return form the http call.
Code for run_ajax service
.service('runajax', ['$http', function ($http) {
this.runajax_function = function (request, callback) {
var url = request.url;
var dataServer = request.dataServer;
// console.log('runajax function called -> ' + url);
// console.log(dataServer);
$http.post(url, dataServer).success(function (data, status, headers, config) {
callback(data);
})
.error(function () {
callback(status);
});
}
}])
I got it working. There was an error with app.set('port', process.env.PORT || 5000); I changed it to var port = process.env.PORT || 8080;
I could send messages before, but I shared passport's sessions with express and socket.io using redis by following this tutorial http://www.scotthasbrouck.com/blog/2016/3/18/passportjs-express-session-with-sockeio and now I can no longer send any chat messages.
Also, in my routes req.isAuthenticated() always returns false but I didn't have this problem before.
This is my server.js.

I had the same problem. I tried to implement passport.socketio like you but I solved my problem without it.
Here is my middleware :
// Express session middleware
var sessionMiddleware = session({ secret: 'secret-key', resave: true, saveUninitialized: true });
// Send Express sessionMiddleware through socket.io
io.use(function(socket, next){
// Params: request object, response object and callback.
sessionMiddleware(socket.request, {}, next);
});
The second parameter (response object) of sessionMiddleware function is empty. This will renders the session read-only.
And Here is how I use passport js session variable to get user informations :
io.on("connection", function(socket){
socket.on('chat message', function(msg){
var passport = socket.request.session.passport; // Get the passport variable
// Check if passport session exists
if (passport && typeof passport !== 'undefined'){
var userSession = passport.user; // Get the user session
// Build JSON with user session data
var message = {
message : msg,
name : userSession.name,
avatar : userSession.avatar
};
io.emit('chat message', message); // Emit my socket
}
});
});
Hope it help.
This was how i was able to solve it.

I am trying to build a chat room, where I pass user session from passport + express to socket.io. but now I cannot emit any messages. io.on does not seem to connect.

What could be the issue?
Per the socket.io docs, these are two server-side initialization sequences that should work:
var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
server.listen(80);
or
var app = require('express').createServer();
var io = require('socket.io')(app);
app.listen(80);
You don't have either of these.
