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;
    }
