Script Preparation code:

var data = {
  content: "This is an example of a message Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse leo tellus, scelerisque et varius sit amet, fermentum quis diam. In vehicula, tortor ut finibus aliquet, purus nisl tincidunt erat, ut faucibus mauris ligula id libero",

};

var dataJson = JSON.stringify(data);

var dataUrl = new URLSearchParams(data).toString();

Tests:

JSON
var obj = JSON.parse(dataJson); var { content, author, to, type, location } = obj;
URLSearchParams
var searchParams = new URLSearchParams(dataUrl); var content = searchParams.get("content"); var author = searchParams.get("author"); var to = searchParams.get("to"); var type = searchParams.get("type"); var location = searchParams.get("location");
