i have the following method to auth my users:

app.all('/*', function(req, res, next) {

    // CORS headers

    res.header(Access-Control-Allow-Origin, *); // restrict it to the required domain

    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');

    // Set custom headers for CORS

    res.header('Access-Control-Allow-Headers', 'Content-type,Accept,X-Access-Token,X-Key');

    if (req.method == 'OPTIONS') {

        res.status(200).end();

    } else {

        next();

    }

});



var auth = require('./auth.js');

router.post('/login', auth.login);

app.all('/api/*', [require('./middlewares/validateRequest')]);

// If no route is matched by now, it must be a 404

app.use(function(req, res, next) {

    var err = new Error('Not Found');

    err.status = 404;

    next(err);

});

And my Auth.js

    var jwt = require('jwt-simple');



var auth = {



    login: function(req, res) {



        var username = req.body.username || '';

        var password = req.body.password || '';



        if (username == '' || password == '') {

            res.status(401);

            res.json({

                status: 401,

                message: Invalid credentials

            });

            return;

        }



        // Fire a query to your DB and check if the credentials are valid

        var dbUserObj = auth.validate(username, password);



        if (!dbUserObj) { // If authentication fails, we send a 401 back

            res.status(401);

            res.json({

                status: 401,

                message: Invalid credentials

            });

            return;

        }



        if (dbUserObj) {



            // If authentication is success, we will generate a token

            // and dispatch it to the client



            res.json(genToken(dbUserObj));

        }



    },



    validate: function(username, password) {

        // spoofing the DB response for simplicity

        var dbUserObj = { // spoofing a userobject from the DB.

            name: 'arvind',

            role: 'admin',

            username: '[email protected]'

        };



        return dbUserObj;

    },



    validateUser: function(username) {

        // spoofing the DB response for simplicity

        var dbUserObj = { // spoofing a userobject from the DB.

            name: 'arvind',

            role: 'admin',

            username: '[email protected]'

        };



        return dbUserObj;

    }

}



// private method

function genToken(user) {

    var expires = expiresIn(7); // 7 days

    var token = jwt.encode({

        exp: expires

    }, require('../config/secret')());



    return {

        token: token,

        expires: expires,

        user: user

    };

}



function expiresIn(numDays) {

    var dateObj = new Date();

    return dateObj.setDate(dateObj.getDate() + numDays);

}



module.exports = auth;

This server runs on port 8080.

So when i attempt to go to http://localhost:8080/login i get the following error message:

    Error: Not Found

   at app.use.bodyParser.urlencoded.extended (/var/www/example/backend/server.js:34:15)

   at next (/var/www/example/backend/node_modules/express/lib/router/route.js:104:14)

However it seems that the rest of my auth is working because if i go to:

http://localhost:8080/api/user

I get: {status:401,message:Invalid Token or Key}

Can anyone tell me why my login does not work?
