Game port to unity: Web posting

Hi,

I am porting a game from Java Native to Unity. While the game is working correctly, I am having trouble posting the score using the same web services.

Java Code:

 public static   String gameConfigURL = "http://192.168.0.140/services/scoreupload.svc/json/GetGameConfigurationLite";
 public static   String scoreUploadURL = "http://192.168.0.140/services/scoreupload.svc/json/Upload";
 public static final  String MagicKey = "0GmWDa6j"; 
 private static    int timeoutConnection = 60000; 
 
  public static enum RequestSource
     { 
        Unknown,
         System, 
         Person; 
     } 

 public static Response sendRequestForResult(Request request, String Url,
         Activity activity, Response response) throws JSONException,
         ClientProtocolException, IOException,ConnectTimeoutException {

     /** Code to create a JSON request from requestObject **/ 
     JSONObject object = request.getJSON();
     JSONObject requestObject = new JSONObject();
     requestObject.put("request", object);
     
     Log.v("","REQUEST:"+requestObject.toString());
     /** Add code to create a HttpPostRequest **/
     DefaultHttpClient client = new DefaultHttpClient();
     HttpPost httpPost = new HttpPost(Url);
     
     HttpParams httpParameters = new BasicHttpParams();
     HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
     HttpResponse httpResponse = null;
     String jsonValueString = null;
     StringEntity se = null;
     try {
         se = new StringEntity(requestObject.toString());
     } catch (Exception e) {
         // TODO: handle exception 
         e.printStackTrace();
     }
     httpPost.setEntity(se);
     httpPost.setHeader("Accept", "application/json");
     httpPost.setHeader("Content-Type", "text/json"); 
     /**
      * add code to attach the JSON object received from request to the
      * HttpPostRequest Add Code to execute HttpRequest
      **/
     httpResponse = client.execute(httpPost);

     /** Get string from the HttpRespnse **/
     jsonValueString = EntityUtils.toString(httpResponse.getEntity());
     
     Log.v("","RESPONSE:"+jsonValueString);

     /** Create JSON object from incoming String **/
     JSONObject repliedObject = new JSONObject(jsonValueString);

     response.fromJSON(repliedObject);  
     return response;

How Do I convert this to unity C#.

So far I have this:

 JSONObject j = new JSONObject ();

     j.AddField ("Id", "1234567890");
     j.AddField ("MagicKey", ApplicationServices.magicKey); 
     j.AddField ("RequestedBy", "09996f84-1a06-e211-a518-001aa020d699");
     j.AddField ("Timestamp", "/Date(1547535370953)/"); 
     j.AddField ("RequestSource", "Person");
     j.AddField ("RequestedGameId", "375b43c0-91be-e011-a505-001aa020d699"); 
     j.AddField ("RequestedPersonId", "09996f84-1a06-e211-a518-001aa020d699");
     string json = j.ToString ();

     Dictionary<string, string> header = new Dictionary<string, string>();
     header.Add ("Accept", "application/json");
     header.Add ("Content-Type", "text/json");

     byte[] encode = Encoding.ASCII.GetBytes (json.ToCharArray ());
 

     WWW getConfig = new WWW (ApplicationServices.gameConfigURL, encode, header);

     yield return getConfig;

     if (getConfig.error != null) {
         Debug.Log (getConfig.error);
     } else {
         Debug.Log (getConfig.text);
     }

This does not seem to work.
