res.redirect from POST


Question

For some reason I cant redirect to /blog once my login is completed. In my login controller I have the following.

module.exports = {

    post: function(req, res) {
         var login = req.body['login'];                      

         if (login && req.body['login']['password'] == "password") {
            console.log('Granted access');
            res.send({redirect: '/blog'});

         }

         else {
             console.log('wrong password');
             res.redirect('back');

         }

    }

};

The jquery ajax

$(document).ready ->

    $('#login-button').click () ->

        $.ajax
            url: '/login'
            type: 'POST'
            data: $('#Password').serialize()
            dataType: 'json'
            success: (data, textStatus, jqXHR) ->
                if typeof data.redirect == 'string'
                    window.location = data.redirect

updated to working code

Accepted Answer

You can't make a redirection after an AJAX. You need to do it yourself in Javascript.

server

post: function(req, res) {
     var login = req.body['login'];          
     app.use(express.bodyParser());


     if (login && req.body['login']['password'] == "tom") {
        var loginPassword = req.body['login']['password'];
        console.log(loginPassword);
        console.log('Granted access');
        res.send({redirect: '/blog'});

     }

     ...

}

client

$(document).ready ->
    $('#login-button').click () ->
        $.ajax
            url: '/login'
            type: 'POST'
            data: $('#Password').serialize()
            dataType: 'json'
            success: (data, textStatus, jqXHR) ->
                if typeof data.redirect == 'string'
                    window.location = data.redirect

This should work.

POSTs are redirected to GETs. You can't redirect to a POST to a POST; you could forward it but that would be weird. I recommend adding logic to your GET route that will handle a logged in versus not logged in user.

Also, 304 likely means your response is being cached by your browser because you used a 301 (permanent redirect, very bad on login, etc.; use 302).
