Tutorial code to go along with fzysqr.com post at http://fzysqr.com/2011/03/27/nodechat-js-continued-authentication-profiles-ponies-and-a-meaner-socket-io/

core

core.js

Include core dependencies.

var _ = require('underscore')._
    , Backbone = require('backbone');

Include our own modules

var models = require('./models/models')
    , auth = require('./lib/auth');

Require redis and setup the client

var redis = require('redis')
    , rc = redis.createClient();

rc.on('error', function (err) {
    console.log('Error ' + err);
});

Setup connect, express, socket, and the connect-redis session store

var express = require('express')
    , app = express.createServer()
    , connect = require('connect')
    , jade = require('jade')
    , socket = require('socket.io').listen(app)
    , RedisStore = require('connect-redis');

app.set('view engine', 'jade');
app.set('view options', {layout: false});
app.use(express.bodyParser());
app.use(express.cookieParser());
app.use(express.session({ store: new RedisStore(), secret: 'Secretly I am an elephant' }));

Route GET /login

Template login.jade

app.get('/login', function (req, res) {
    res.render('login');
});

Route POST /login

Calls the authentication module to verify login details. Failures are redirected back to the login page.

If the authentication module gives us a user object back, we ask connect to regenerate the session and send the client back to index. Note: we specify a long cookie age so users won't have to log in frequently. We also set the httpOnly flag to false (I know, not so secure) to make the cookie available over Flash Sockets.

app.post('/login', function (req, res) {
    auth.authenticateUser(req.body.username, req.body.password, function (err, user) {
        if (user) {
            // Regenerate session when signing in to prevent fixation 
            req.session.regenerate(function () {
                // Store the user's primary key in the session store to be retrieved, or in this case the entire user object
                console.log('regenerated session id ' + req.session.id);
                req.session.cookie.maxAge = 100 * 24 * 60 * 60 * 1000; //Force longer cookie age
                req.session.cookie.httpOnly = false;
                req.session.user = user;

                console.log('Storing new hash for user ' + user.get('name') + ': ' + req.session.user.get('hashPass'));
                res.redirect('/');
            });
        } else {
            req.session.error = 'Authentication failed, please check your username and password.';
            res.redirect('back');
        }
    });
});

Route GET /signup:

Template signup.jade

app.get('/signup', function (req, res) {
    res.render('signup');
});

Route POST /signup

Calls createNewUserAccount() in the auth module, redirects to /login if a user object is returned. Redirects to /signup if not.

app.post('/signup', function (req, res) {
    auth.createNewUserAccount(req.body.username, req.body.password1, req.body.password2, req.body.email, req.body.ponies, function (err, user) {
        if ((err) || (!user)) {
            req.session.error = 'New user failed, please check your username and password.';
            res.redirect('back');
        }
        else if (user) {
            res.redirect('/login');
        }
    });

});

Tell connect to destory the session.

app.get('/logout', function (req, res) {
    req.session.destroy(function () {
        res.redirect('home');
    });
});

Serve up any static file requested by the client

TODO should restrict this to only server *public* routes.

app.get('

.(js|css)', function (req, res) { res.sendfile('./' + req.url); });

/* Middleware that decides what a valid login looks like. In this case, just verify that we have a session object for the user.

This is an express route middleware. Control is passed to the middleware function before the route function is called. We use restrictAccess() to verify that we have a valid user key in the session, implying that authentication has succeeded, before we send the client to the index.jade template. If we do not have a valid user in the session, then we redirect to the '/login' route. This effectively locks down our '/' route from unauthenticated access. You could add the restrictAccess() all to any route you want to protect.

function restrictAccess(req, res, next) {
    if (req.session.user) {
        next();
    } else {
        req.session.error = 'Access denied!';
        res.redirect('/login');
    }
}

Server up the main index view.

Calls the restrictAccess() middleware.

app.get('/', restrictAccess, function (req, res) {
    res.render('index', {
        locals: { name: req.session.user.name, hashPass: JSON.stringify(req.session.user.hashPass) }
    });
});

//create local state
var activeClients = 0;
var nodeChatModel = new models.NodeChatModel();

When we have a client that shouldn't be connected, kick 'em off!'

  • param: object client

  • param: function fn

function disconnectAndRedirectClient(client, fn) {
    console.log('Disconnecting unauthenticated user');
    client.send({ event: 'disconnect' });
    client.connection.end();
    return fn();
}

Event handler for client disconnects. Simply broadcasts the new active client count.

  • param: object client

function clientDisconnect(client) {
    activeClients -= 1;
    client.broadcast({clients: activeClients});
}

Event handler for new chat messages. Stores the chat in redis and broadcasts it to all connected clients.

  • param: object client

  • param: object socket

  • param: json string msg

function chatMessage(client, socket, msg) {
    var chat = new models.ChatEntry();
    chat.mport(msg);

    rc.incr('next.chatentry.id', function (err, newId) {
        chat.set({id: newId});
        nodeChatModel.chats.add(chat);
        
        var expandedMsg = chat.get('id') + ' ' + client.user.name + ': ' + chat.get('text');
        console.log('(' + client.sessionId + ') ' + expandedMsg);

        rc.rpush('chatentries', chat.xport(), redis.print);

        socket.broadcast({
            event: 'chat',
            data: chat.xport()
        }); 
    }); 
}

Handle the new connection event for socket.

connectSession() is a helper method that will verify a client's validity by checking for a cookie in the request header, then, if we find it, pulling their session out of redis.

We then use the helper method in the 'connection' handler for our socket listener. Instead accepting any user connection, we are going to check that the client has a valid session (meaning they logged in). If they don't, give them the boot! If they do, then we store a copy of the session data (yay we have access!) in the client object and then setup the rest of the socket events. Finally, send them a welcome message just to prove that we remembered their profile.

socket.on('connection', function (client) {
    client.connectSession = function (fn) {
        if (!client.request || !client.request.headers || !client.request.headers.cookie) {
            disconnectAndRedirectClient(client, function () {
                console.log('Null request/header/cookie!');
            });
            return;
        }

        console.log('Cookie is' + client.request.headers.cookie);

        var match, sid;
        match = client.request.headers.cookie.match(/connect\.sid=([^;]+)/);
        if (!match || match.length < 2) {
            disconnectAndRedirectClient(client, function () {
                console.log('Failed to find connect.sid in cookie');
            });
            return;
        }

        sid = unescape(match[1]);

        rc.get(sid, function (err, data) {
            fn(err, JSON.parse(data));
        });
    };

    client.connectSession(function (err, data) {
        if (err) {
            console.log('Error on connectionSession: ' + err);
            return;
        }

        client.user = data.user;

        activeClients += 1;
        client.on('disconnect', function () {   
            clientDisconnect(client);
        });
        client.on('message', function (msg) {
            chatMessage(client, socket, msg);
        });

        console.log('User successfully connected with ' + data.user.name + ' hash ' + data.user.hashPass); 

        socket.broadcast({
            event: 'update',
            clients: activeClients
        });

        var ponyWelcome = new models.ChatEntry({name: 'PonyBot', text: 'Hello ' + data.user.name + '. I also feel that ponies ' + data.user.ponies + '. Welcome to nodechat.js'});

        socket.broadcast({
            event: 'chat',
            data: ponyWelcome.xport()
        });
    });
});

Fire up the webserver

app.listen(8000);

controllers

controllers/controllers.js

// //Controllers // var NodeChatController = { init: function(options) { this.socket = new io.Socket(null, {port: 8000}); var mysocket = this.socket; this.userName = options.userName; this.hashPass = options.hashPass;

    this.model = new models.NodeChatModel({userName: this.userName, hashPass: this.hashPass});
    this.view = new NodeChatView({model: this.model, socket: this.socket, el: $('#content')});
    var view = this.view;

    this.socket.on('message', function(msg) {view.msgReceived(msg)});
    this.socket.connect();

    this.view.render();

    return this;
}

};

auth

lib/auth.js

This will be a CommonJS module so we need to start off with some setup.

Here we are checking to see if this code is included as a module. If it is, we go ahead and include our dependencies (in this case, our models lib, redis, and hash + friends). If we are not a module, we may as well explode because the rest of the code won't run without redis and hash.

(function () {
    if (typeof exports !== 'undefined') {
        redis = require('redis');
        rc = redis.createClient();
        models = require('../models/models');

        //joose is required to support the hash lib we are using
        require('joose');
        require('joosex-namespace-depended');
        require('hash');
    } 
    else {
        throw new Error('auth.js must be loaded as a module.');
    }

Checks to see if the user exists in redis. If it does, it calls verifyUserAccount(). Otherwise callback with an error.

  • para: m : {string} name
  • para: m : {string} pass
  • para: m : {function} fn
  • ap: i : public
exports.authenticateUser = function(name, pass, fn) {
        console.log('[authenticate] Starting auth for ' + name + ' with password ' + pass);
        
        var rKey = 'user:' + name;
        rc.get(rKey, function(err, data){
            if(err) return fn(new Error('[authenticateUser] SET failed for key: ' + rKey + ' for value: ' + name));

            if (!data) {
                fn(new Error('[authenticateUser] invalid password'));
            }
            else {
                console.log('[authenticateUser] user: ' + name + ' found in store. Verifying password.');
                verifyUserAccount(data, pass, fn)
            }
        });
    };

Steps through the process of retreiving the salt, calculating the hash of the passed in password, then comparing it to the stored hash in redis.

If successful, create a new user model and pass it to the callback.

Otherwise, any failure along the way means we callback with an error.

Assumes the passed in user exists in redis.

  • para: m : {string} foundUserName
  • para: m : {string} pass
  • para: m : {function} fn
  • ap: i : private
var verifyUserAccount = function(foundUserName, pass, fn) {
        var rKey = 'user:' + foundUserName;

        rc.get(rKey + '.salt', function(err, data){
            if(err) return fn(new Error('[verifyUserAccount] GET failed for key: ' + rKey + '.salt')); 

            if(data) {
                var calculatedHash = Hash.sha512(data + '_' + pass);
                rc.get(rKey + '.hashPass', function(err, data) {
                    if(err) return fn(new Error('[verifyUserAccount] GET failed for key: ' + rKey + '.hashPass'));

                    if (calculatedHash === data) {
                        console.log('[verifyUserAccount] Auth succeeded for ' + foundUserName + ' with password ' + pass);

                        rc.get(rKey + '.profile', function(err, data) {
                            if(err) return fn(new Error('[verifyUserAccount] GET failed for key: ' + rKey + '.profile' + ' for user profile'));

                            var foundUser = new models.User();
                            foundUser.mport(data);
                            foundUser.set({'hashPass': calculatedHash});

                            return fn(null, foundUser);
                        });
                    }
                    else {
                        return fn(new Error('[verifyUserAccount] invalid password'));
                    }
                });
            }
            else {
                return fn(new Error('[verifyUserAccount] salt not found'));
            }
        });
    }

Verifies that the two passwords match, then use the current timestamp to salt a hash of the password. Store it all in a user model which we will save as a poor man's profile if everything succeeds.

Any failure along the way means we callback with an error.

  • para: m : {string} name
  • para: m : {string} pass1
  • para: m : {string} pass2
  • para: m : {string} email
  • para: m : {string} ponies
  • para: m : {function} fn
  • ap: i : public
exports.createNewUserAccount = function(name, pass1, pass2, email, ponies, fn) {
        if (pass1 !== pass2) return fn(new Error('[createNewUserAccount] Passwords do not match'));

        var newUser = new models.User({name: name, email: email, ponies: ponies});

        var rKey = 'user:' + name;

        rc.set(rKey, name, function(err, data){
            if(err) return fn(new Error('[createNewUserAccount] SET failed for key: ' + rKey + ' for value: ' + name));

            var salt = new Date().getTime();
            rc.set(rKey + '.salt', salt, function(err, data) {
                if(err) return fn(new Error('[createNewUserAccount] SET failed for key: ' + rKey + '.salt' + ' for value: ' + salt));

                var hashPass = Hash.sha512(salt + '_' + pass1);
                rc.set(rKey + '.hashPass', hashPass, function(err, data) {
                    if(err) return fn(new Error('[createNewUserAccount] SET failed for key: ' + rKey + '.hashPass' + ' for value: ' + hashPass));

                    rc.set(rKey + '.profile', newUser.xport(), function(err, data) {
                        if(err) return fn(new Error('[createNewUserAccount] SET failed for key: ' + rKey + '.profile' + ' for user profile'));

                        newUser.set({'hashPass': hashPass});
                        return fn(null, newUser);
                    });

// Expose wrapper.prototype as _.prototype _.prototype = wrapper.prototype;

// Helper function to continue chaining intermediate results. var result = function(obj, chain) { return chain ? _(obj).chain() : obj; };

// A method to easily add functions to the OOP wrapper. var addToWrapper = function(name, func) { wrapper.prototype[name] = function() { var args = slice.call(arguments); unshift.call(args, this.wrapped); return result(func.apply(, args), this._chain); }; };

// Add all of the Underscore functions to the wrapper object. .mixin();

// Add all mutator Array functions to the wrapper. each(['pop', 'push', 'reverse', 'shift', 'sort', 'splice', 'unshift'], function(name) { var method = ArrayProto[name]; wrapper.prototype[name] = function() { method.apply(this.wrapped, arguments); return result(this.wrapped, this._chain); }; });

// Add all accessor Array functions to the wrapper. each(['concat', 'join', 'slice'], function(name) { var method = ArrayProto[name]; wrapper.prototype[name] = function() { return result(method.apply(this.wrapped, arguments), this.chain); }; });

// Start chaining a wrapped Underscore object. wrapper.prototype.chain = function() { this._chain = true; return this; };

// Extracts the result from a wrapped and chained object. wrapper.prototype.value = function() { return this._wrapped; };
