How to nest objects when building JSON with JSONObject

Question

I\'m trying to encode this string for a POST request. Can anyone tell me how I can encode

{\"jsonrpc\": \"2.0\", \"method\": \"Files.GetSources\",         


        

Answer 1

If you're asking how you'd put the nested params object in there, you'd probably do:

JSONObject params = new JSONObject();
params.put("media", "music");

obj.put("params", params);

---

To use an array (per your comments below), you'd do something like this:

JSONArray properties = new JSONArray();
properties.put("resume");
properties.put("genre");
properties.put("studio");
...

JSONObject params = new JSONObject();
params.put("properties", properties);

obj.put("params", params);

Answer 2

JSONOjbect obj = new JSONObject().put("jsonrpc", "2.0")
    .put("method", "Files.GetSources").put("id", 1)
    .put("params", new JSONObject().put("media", "music"));

Chaining .put() like this is possible because put() returns the object it was called on - for this exact purpose.

Answer 3

Well, if you do have the string before hand, you can simply do

JSONObject object = JSONObject.getJSONObject("{\"jsonrpc\": \"2.0\", \"method\": \"Files.GetSources\", \"params\":{\"media\":\"music\"}, \"id\": 1}");

Answer 4

You have two choices. You can create another object that holds "media":"music" and then put that in the original JSONObject or you can just pass this whole string into the JSONObject constructor and have it parse it for you.
