redirect url after setting cookie

[Neil Camara]

Hi folks,

I'm trying to mimic a code that I wrote in php. What the php does is parse GET data request, set the GET data in a cookie then finally redirect the client to another path of the same domain.

The problem  is the "redirect" is not working and I'm getting this message:

Error: Can't set headers after they are sent.

    at ServerResponse.OutgoingMessage.setHeader (http.js:689:11)

Here is the code

app.get('/sdm', function(req, res){
 
    var userData = {
        isAuthenticated  : true,
        username         : req.param('email'),
        resourceId       : req.param('userresourceid'),
        bearerToken      : req.param('token'),
        tokenResourceId  : req.param('tokenresourceid'),
        firstname        : req.param('fname'),
        lastname         : req.param('lname'),
        gravatarLink     : 'http://i.imgur.com/AVmo4I3.png',
        expirationDate   : '2014-12-31T00:00:00.000Z',
        locale           : 'en'
    };
 
    res.cookie('credentials', userData).send();
    res.redirect('http://localhost:3000/reloaded');
 
});

Any help would be greatly appreciated.

Thanks,

Neil

Here is the code

    res.cookie('credentials', userData).send();
    res.redirect('http://localhost:3000/reloaded');

Both 'send' and 'redirect' send the response; you only get to do that once. If you remove the send, the redirect will do it and it will work as you expect.

The cookies will still be sent -- they're queued up as headers, ready to send before the body starts being sent (or in this case, skipped, since redirects have no body)
