Invalid JSON with Parse.com Request in Java

Question

I'm trying to copy Parse's Curl REST API code into Java as shown in their documentation here :

curl -X GET \
-H "X-Parse-Application-Id: APPLICATION-ID" \
-H "X-Parse-REST-API-Key: REST-API-KEY" \
-G \
--data-urlencode 'where={"playerName":"Sean Plott","cheatMode":false}' \
https://api.parse.com/1/classes/GameScore

Essentially, I'm trying to find a user's item in table Items based upon the selected user's objectid.

Currently, I'm just testing by running my program as a Java application but I'm getting a {"code":107,"error":"invalid JSON"} error from the response. I just can't seem to get the data-urlencode of the curl correct (or it could be I'm completely doing it wrong). If it matters, I'm using OkHttp.

Here is my code below:

public List<Item> getItemList(String user) {
    final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    String userID = getUserID(user);
    Gson gson = new Gson();

    System.out.println(userID);
    if(userID != null) {

        String json = "'where={\"Owner:\"" + userID + "\"}'";
        RequestBody reqBody = RequestBody.create(JSON, json );

        Request request = new Request.Builder()
        .url("https://api.parse.com/1/classes/Items")
        .header("Content-type", "application/json")
        .post(reqBody)
        .addHeader("X-Parse-REST-API-Key", REST_API_KEY)
        .addHeader("X-Parse-Application-Id", APPLICATION_ID)
        .build();

        Response resp;
        try {
            resp = client.newCall(request).execute();
            String html = resp.body().string();
            System.out.println("Html is: " + html);
        } catch (Exception e) {

        }

    } else {
        return null; //TODO: Throw no user found exception
    }
      return null;
}

It looks ugly, but right now I'm just trying to get it to work. The getUserId() method works correctly and returns the correct user ID string. Any help would be appreciated.

I don't think you've understood what the "--data-urlencode" option does to the curl request. The request the curl line sends looks something like the encoded version:

encoded > https://api.parse.com/1/classes/GameScore?where=%7B"playerName"%3A"Sean%20Plott"%2C"c
decoded > https://api.parse.com/1/classes/GameScore?where={"playerName":"Sean Plott","cheatMode":false}

This is a GET-request, as specified in the documentation, and it looks like you're trying to send a POST-request. Have you tried to send a GET-request with the data url-encoded?
