How to configure Angular $resource (ngResource) to pull data from another domain using CORS

问题

I'd like to be able to setup resources using $resource using CORS to request my data. I've got CORS working with $http but the same techniques don't apply to $resource and I was hoping someone can come to my rescue and show me how with $resource.

I've modified the last step of the Angular tutorial to use CORS by hacking the phonecatServices service, in the services.js file.

I found this example which uses the $http.defaults.useXDomain = true; delete $http.defaults.headers.common['X-Requested-With'];line to get angular to request the data using CORS but if I try $resource.defaults.useXDomain = true; I get the error: "Cannot set property 'useXDomain' of undefined".

I presume $resource doesn't have this property, so my question is, how do I configure $resource to make cross domain resource requests using CORS.

Here's my code:

angular.module('phonecatServices', ['ngResource']).
    factory('Phone', function($resource){
  return $resource('http\\://localhost\\:8080/:phoneId.json', {}, {
    query: {params:{phoneId:'phones'}, isArray:true}
  });
});

I get the following error when I try to make the request: Object #<Resource> has no method 'push'

EDIT

I've tried setting up for $http and it works most of the time, but when the call is made to the resource query, in this case Phone.get(phoneId); this seems to throw the above error.

Calling code that I suspect is causing the error (from controllers.js step 11 angular tutorial):

function PhoneDetailCtrl($scope, $routeParams, Phone) {
  $scope.phone = Phone.get({phoneId: $routeParams.phoneId}, function(phone) {
    $scope.mainImageUrl = phone.images[0];
  });

  $scope.setImage = function(imageUrl) {
    $scope.mainImageUrl = imageUrl;
  }
}

If I remove the innards of the above method the code runs fine (without obtaining the image for the website), but I don't understand why this wouldn't work? I have set up the $http service to use CORS so that should pass it to $resource apparently.

Can anyone shed any light on it? (any working example code would be greatly appreciated).

Just so anyone visiting this question is aware, none of the answers below have really answered the question, I am researching an answer myself but if anyone spots this and has an answer I'd greatly appreciate it still.

Currently looking into this project, seems to allow everything I'm looking for: https://github.com/jpillora/xdomain

OK, the solution I've found for my project is xdomain: https://github.com/jpillora/xdomain

I accept that this may not be suitable for everyone but it's a decent cross browser solution and whilst we're stuck with IE<10 this seems to be the best solution. (I am aware IE8 and IE9 provide partial support but that as always with IE isn't full support and I don't want to have to waste time doing another work around for IE).

Thanks to everyone who provided answers to the question.

I think this sample could work for you

angular.module('myBeerApp.services', ['ngResource']).
  value('version', '0.1').
  factory('beerDB', function($resource) {
    return $resource('URL',{
      alt:'json',
      appToken:'TOKEN',
      q:'rock',
      callback: 'JSON_CALLBACK'
    },
      {
        get: {
          method:'JSONP',
          headers: {
            'Content-Type': 'application/json',
            'Accept': 'application/json'
            }
          }
      });
  });

Are you calling useXDomain = true in your app.config();
