How to get "onResourceReceived" results back to Node through wrapper?

[systemxcom]

In webshot.phantom.js, I can get back the results of this option by grabbing the args array. Is there anyway to get the args array back to Node through your wrapper?

Option:
onResourceReceived: {
fn: function(response) {
}, context: {urlSource: urlLoc, capId: fileName},},

webshot.phantom.js
/*
* Bind the function fn to the context context in a serializable manner.
* A tiny bit of a hack.
*
* @param (String) fn
* @param (Object) context
*/
function buildEvaluationFn(fn, context) {
return function() {
var args = Array.prototype.slice.call(arguments);
console.log(JSON.stringify(context))
var adHost = args[0]['url'];
console.log(adHost);
page.evaluate(function(fn, context, args) {
eval('(' + fn + ')').apply(context, args);
}, fn, context, args);
};
}
