Angular resource middleware to catch response

I have an angular service that looks like:

service('PortfolioService', ['$resource', function($resource) {
    return $resource('/api/', {}, {
        stock_positions: {
            method: 'GET',
            url: '/api/stock_positions',
            isArray: false
        }
    });
}]).

And in a controller:

PortfolioService.stock_positions(function someCB(result){       
   //do something with the result
});

If you aren't logged in the api returns an object that looks like:

{
  error: "Login required",
  redirect: "/login"
}

I would like to have something that would catch this in the resource, handle it (redirecting to /login), and not pass on to someCB in the controller.

Is there a way to do this with $resource?

It looks like I just needed to do the following:

service('PortfolioService', ['$resource', function($resource) {
    return $resource('/api/', {}, {
        stock_positions: {
            method: 'GET',
            url: '/api/stock_positions',
            isArray: false,
            interceptor:{
                response:function(response){
                    //do stuff here to catch the response before passing it on.
                    return response;
                },
                responseError: function(rejection){
                    console.log(rejection);
                }
            }
        }
    });
}]).

I think this can be achieved by angular interceptor.

https://docs.angularjs.org/api/ng/service/$http

 $httpProvider.interceptors.push(['$location', function($location) {
      return {
       'response': function(response) {
          if(response.redirect.indexOf('/login'){
          // redirect to login
          }
          return response;
        }
      };
    }]);
