Sure @Timo_Kuisma1 very close to achieve what I want but only problem remaining is change in format. Please look into this or suggest me something how can I achieve this with json format.
this is how I achieve in js.
Imagine we have this object in JavaScript:
var obj = { name: “John”, age: 30, city: “New York” };
Use the JavaScript function JSON.stringify() to convert it into a string.
var myJSON = JSON.stringify(obj);
myJSON is now a string, and ready to be sent to a server:
{“name”:“John”,“age”:30,“city”:“New York”}
Not sure how we can achieve this in groovy or java please.
