parse and get specific field from HTTP response in java

Question

I try to parse a HTTP response to a JSONObject and retrieve some fields, coould be a String or int. My response is a json array like this:

[{nid: "24161",changed: 1445936169,created: "1444728767",language: "en",status: 1,title: "bicycle",type: "product",uid: "2172",vid: "24161"}]

And I tried using:

JSONObject myObject = new JSONObject(response);

And gson , still after parsing the response turns to {}. Thanks for any help.

You must use JSONArray instead of JSONObject

JSONArray array = new JSONArray(response);

You can then iterate throw the array and get the fields you want

for(int i=0; i<array.length(); i++) {
    JSONObject object = array.getJSONObject(i);
    String nid = object.getString("nid");
    int changed = object.getInt("changed");
    //...
}

You are parsing json array into object. Use JSONArray instead of JSONObject

JSONArray myArray = new JSONArray(response);

you can get your object by index from your array.

Works like charm, but how to get a field by key?

Adil Shaikh Over a year ago

once you got the object form your array, you can call myObjectAtIndexZero.get("nid")

will it work for other indexes as well, marking your answer as right when I can.
