Cannot GET /auth/twitter/callback while using twitter oauth in nodejs

I'm trying to do twitter oauth in nodejs using passportjs but getting error

Cannot GET /auth/twitter/callback?oauth_token=alksdkalsjdsjd23232378skjdfjsdhf&oauth_verifier=234jjh23j4k234k23h4j2h342k34hj


Here is my node js code

var express = require('express')
, passport = require('passport')
, util = require('util')
, GoogleStrategy = require('passport-google').Strategy
, TwitterStrategy = require('passport-twitter').Strategy;


passport.serializeUser(function(user, done) {
done(null, user);
});

passport.deserializeUser(function(obj, done) {
done(null, obj);
});


passport.use(new TwitterStrategy({
consumerKey: 'xxxxxxxxxxxxxxxxxxxx',
consumerSecret: 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
callbackURL: 'http://127.0.0.1:3000/auth/twitter/callback'
},
function(token, tokenSecret, profile, done) {
process.nextTick(function () {
return done(null, profile);
});
}
));


var app = express();

// configure Express
app.configure(function() {
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.logger());
app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.session({ secret: 'keyboard cat' }));
// Initialize Passport! Also use passport.session() middleware, to support
// persistent login sessions (recommended).
app.use(passport.initialize());
app.use(passport.session());
app.use(app.router);
app.use(express.static(__dirname + '/../../public'));
});


app.get('/', function(req, res){
res.render('index', { user: req.user });
});



app.get('/login', function(req, res){
res.sendfile('./views/auth.html');
});




app.get('/auth/twitter', passport.authenticate('twitter'));

app.get('auth/twitter/callback',
passport.authenticate('twitter', { successRedirect: '/success',
failureRedirect: '/login' }));

app.get('/success', function(req, res){
res.send("success logged in");
});

app.listen(process.env.PORT || 3000);

Answer

EDIT There is missing / in auth/twitter/callback route definition.

Also for the routers /auth/twitter and auth/twitter/callback, passport.authenticate() as middleware will do the authentication, and you should have route handling functions.

So the definition of your routes should look something like:

app.get('/auth/twitter', 
         passport.authenticate('twitter'),
         function(req, res) {}); // empty route handler function, it won't be triggered
app.get('/auth/twitter/callback', 
         passport.authenticate('twitter', { 
                                successRedirect: '/success',
                                failureRedirect: '/login' }),
         function(req, res) {}); // route handler
