express - Problems calling Facebook with Angular $resource -

if use simple button href="users/facebook" in login form, facebook callback works fine.

i want change service function calls "users/facebook" not working. have:

login.html

<a href="" ng-click="facebooklogin()" class="btn btn-primary"><span class="fa fa-facebook"></span>  

controllers.js

$scope.facebooklogin = function() {         console.log('facebooklogin called');         authfactory.facebooklogin();     }; 

services.js

authfac.facebooklogin = function() {       console.log('in services/facebooklogin');       $resource(baseurl + "users/facebook").get(function(){     });     }; 

routes/users.js

//not working     router.get('/facebook', passport.authenticate('facebook'),       function(req, res){         console.log('facebook called');       }); 

according console $resource call "https://localhost:3443/users/facebook" works ok router.get('/facebook) not working. can't see what's going wrong.

edit:

postman get https://localhost:3443/users/facebook works can't understand why $resource(baseurl + "users/facebook").get(function() isn't working.

i thought i'd taken care of cors adding following server file:

app.use(function(req, res, next) {   res.setheader('access-control-allow-origin', '*');   res.setheader('access-control-allow-methods', 'get, post');   res.setheader('access-control-allow-headers', 'x-requested-with,content-type, authorization');   next(); }); 

but still issue in end fixed using:

window.location = window.location.protocol + '//' + window.location.host + '/users/facebook'; 

instead of:

$resource(baseurl + "users/facebook") 

now facebookcallback function works.
