How to access raw JSON string of ngResource response?

I use ngResource to query a JSON service and per default Angular parses the response. Unfortunately I'd also like to have access to the raw response string.

Here is a snippet of what I'd like to achieve:

var app = angular.module('plunker', ['ngResource']);

app.factory('DateResource', function($resource, $http) {
  var raw = null,
    resource = $resource('http://date.jsontest.com/', {}, {
      query: {
        method: 'GET',
        transformResponse: [
          function(data) {
            raw = data;
            return data;
          }
        ].concat($http.defaults.transformResponse).concat([
          function(data) {
            data.$raw = raw;
            return data;
          }
        ])
      }
    });
  return resource;
});

app.controller('MainCtrl', function($scope, DateResource) {
  DateResource.query({}, function(response) {
    console.log('response:', response); // should be parsed JSON object
    console.log('response.$raw:', response.$raw); // should be raw JSON string
  });
});

Checkout the full example: http://plnkr.co/edit/RSwrRQFo1dEGDkxzRTcF

This implementation using two transformRequest functions and a raw variable in the parent scope is not really a good idea, since the calls might be asynchronous...

Is there a possibility to identify the response, so I can remember the raw content per response and attach it later in the second transformResponse? Or do you know another solution?

You can do that by overriding the transform defaults and use the angular.fromJson(rawData)

resource = $resource('http://date.jsontest.com/', {}, {
  query: {
    method: 'GET',
    transformResponse: transformGet
  }
});


function transformGet(json, headerGetter) {
  var fromJson = angular.fromJson(json);
  fromJson.json = json ;
  return fromJson;
}

  DateResource.query({}, function(response) {
    console.log('response:', response); // should be parsed JSON object
    console.log('response.$raw:', angular.toJson(response)); // should be raw JSON string
  });
});
