How to parse JSON results from Unirest call

Question

I'm using the Unirest library to retrieve JSON from a Mashape API. I have the call working using the following code:

HttpResponse<JsonNode> request = Unirest.get(URL)   .header("X-Mashape-Authorization", MASHAPE_AUTH)   .asJson(); 

This returns my JSON in the form of HttpResponse<JsonNode>, which I am unfamiliar with.

From reading the limited documentation, It seems that I have to call getBody() on the response object in order to get a JsonNode object back. I still have no idea what to do with the JsonNode object however.

What is the best way to begin to parse this data?

Edit: In case it helps with giving examples, the JSON I want to parse looks like this:

{   "success": "1",   "error_number": "",   "error_message": "",   "results": [     {       "name": "name1",       "formatedName": "Name 1"     },     {       "name": "testtesttest",       "formatedName": "Test Test Test"     },     {       "name": "nametest2",       "formatedName": "Name Test 2"     },     {       "name": "nametest3",       "formatedName": "Name Test 3"     }   ] }

Was trying to figure this out today for myself. The source code is probably the only documentation you're going to get. Here's the tl;dr

// the request from your question HttpResponse<JsonNode> request = Unirest.get(URL)   .header("X-Mashape-Authorization", MASHAPE_AUTH)   .asJson();  // retrieve the parsed JSONObject from the response JSONObject myObj = request.getBody().getObject();  // extract fields from the object String msg = myObj.getString("error_message"); JSONArray results = myObj.getJSONArray(); 

Here's some more explanation of the spelunking I did:

From the HttpResponse class we can see that getBody() is going to return the instance variable body, which gets assigned on line 92 as:

this.body = (T) new JsonNode(jsonString) 

So then we need to look at the JsonNode class. The constructor takes a string representing the JSON to be parsed and attempts to create either a JSONObject or a JSONArray. Those objects come from org.json which is well documented, thankfully.
