how to send json as a response after passport authenticationin node.js

Question

I am trying this git example.

Which works well when I integrated it with my project, but what I want to achieve is to send json as a response to the client/request, instead of successRedirect : '/profile' & failureRedirect : '/signup'.

Is it possible to send a json, or is there some other methods to get the same?

Any help will be appreciated,TU

Answer 1

There is an official Custom Callback documentation:

app.get('/login', function(req, res, next) {
  passport.authenticate('local', function(err, user, info) {
    if (err) { return next(err); }
    if (!user) { return res.redirect('/login'); }
    req.logIn(user, function(err) {
      if (err) { return next(err); }
      return res.redirect('/users/' + user.username);
    });
  })(req, res, next);
});

Answer 2

here I modified my code to send json as a response

// process the signup form
app.post('/signup', passport.authenticate('local-signup', {
    successRedirect : '/successjson', // redirect to the secure profile section
    failureRedirect : '/failurejson', // redirect back to the signup page if there is an error
    failureFlash : true // allow flash messages
}));

app.get('/successjson', function(req, res) {
    res.sendfile('public/index.htm');
});

app.get('/failurejson', function(req, res) {
    res.json({ message: 'hello' });
});
