JSON Method

I came across a scenario in my work place where I need to use client script WebService REST message to call a MID server to get result from the actual server which is behind the firewall. However, this time I will just share how I use client script to get the results and assigned them to object using JSON (JavaScript Object Notation) method in Servicenow.

try {
		 var r = new sn_ws.RESTMessageV2('NAT DNS API', 'dns_zone');

		 var response = r.execute();
		 var responseBody = response.getBody() ;
		var obj = JSON.parse(responseBody);
		obj.httpStatus = response.getStatusCode();
		var oj = JSON.stringify(obj);

		 gs.setRedirect("x_person.do?x_person="+  encodeURI(oj));
		catch(ex) {
		var message = ex.getMessage();


How to use JSON?

From above example. I used two JSON method which is JSON.parse and JSON.stringify. ‘response’ variable will contain the result in string format after executed.

JSON.parse = Convert string to object. As I need to add a message element  to contain message and assigning the status code to  the existing element.

JSON.stringify = Convert object to string. In order for me to be able to post back the values, I have to convert back to string before I postback.

Below are some helpful sites for your better understanding:

  1. JSON
  2. Mozzila Web Doc


Here is how to use it for posting back from client side to server side for processing in my post.

There you go. Hope you have a better understanding on this.
