JSONArray jsonArray;
  try {
  　　 jsonArray = new JSONArray(productStr);
  　　 int iSize = jsonArray.length();           
   　　for(int i = 0; i < iSize; i++) {        
              JSONObject jsonObj = jsonArray.getJSONObject(i);  
              String product_id = jsonObj.get("product_id").toString();
              String is_anonymous = jsonObj.get("is_anonymous").toString();
