FASTJSON 各种类型相互转换

一：JSONObject获取JSONArray转JSONObject获取某个属性值

       String httpPost4Instream = http.httpPost4Instream
       JSONObject jsonbject = JSONObject.fromObject(httpPost4Instream);
       JSONArray jsonArray = jsonbject.getJSONArray("stores");
       String string = jsonArray.getString(0);
       JSONObject fromObject = JSONObject.fromObject(string);
       String startDate = fromObject.getString("startDate");
       String endDate = fromObject.getString("endDate");
       param.setFromDate(Long.valueOf(startDate).longValue());
       param.setToDate(Long.valueOf(endDate).longValue());
