Android接口传递Json数组的处理方式

     public static XTResult<Void> addTravel(String uuid, String travelName, String travelId, String startDate,
             JSONArray travelCities) {
         String partUrl = "/travelModel/addTravelModel";
         XTResult<Void> result = null;
         JSONObject jsonObject = new JSONObject();
         try {
             jsonObject.put("token", ServiceCenter.TOKEN_VALUE);
             jsonObject.put("uuid", uuid);
             jsonObject.put("name", travelName);
             jsonObject.put("travelId", travelId);
             jsonObject.put("startTime", startDate);
             jsonObject.put("travelCities", travelCities);
             StringEntity entity = new StringEntity(jsonObject.toString(), HTTP.UTF_8);
             entity.setContentType("application/json");
             entity.setContentEncoding("utf-8");
             String response = ServiceCenter.postEntityApiV1(partUrl, entity);
             Logger.d(Const.TAG_LOG, "addTravel:" + response);
             if (!TextUtils.isEmpty(response)) {
                 result = new Gson().fromJson(response, XTResult.class);
             }
         } catch (JSONException e) {
             e.printStackTrace();
         } catch (UnsupportedEncodingException e) {
             e.printStackTrace();
         }
         return result;
     }
