大家都说写博客是个好习惯，今天我也开始我的博客之旅，记录自己所有做过的项目中被卡的自认为的难点吧~~~~

这是使用HttpClient方式，从聚合数据里面获取到的资源，查询火车班次信息。下面这个方法是根据站站查询获得的数据。聚合数据链接

public List<Station_to_Station> queryByZhanZhan(String startstation,String endstation,String time) {List<Station_to_Station> lists = new ArrayList<Station_to_Station>();String url = "http://apis.juhe.cn/train/yp?key=您从聚合数据里申请的key值&dtype=json&from=" + startstation+ "&to=" + endstation+ "&date="+time;HttpGet httpGet = new HttpGet(url);HttpClient client = new DefaultHttpClient();HttpResponse httpResponse;try {httpResponse = client.execute(httpGet);int code = httpResponse.getStatusLine().getStatusCode();if (code == 200) {String result = EntityUtils.toString(httpResponse.getEntity(),"utf-8");JSONObject jsonObject = new JSONObject(result);String resultCode = jsonObject.getString("reason");if ("查询成功".equals(resultCode)) {JSONArray jsonArray = jsonObject.getJSONArray("result");for (int i = 0; i < jsonArray.length(); i++) {JSONObject jsonObject2 = jsonArray.getJSONObject(i);Station_to_Station station = new Station_to_Station();String trainOpp = jsonObject2.getString("train_no");// 车次名称station.setTrainOpp(trainOpp);String start_station = jsonObject2.getString("from_station_name");// 出发站station.setStart_station(start_station);String end_station = jsonObject2.getString("to_station_name");// 终点站station.setEnd_station(end_station);String leave_time = jsonObject2.getString("start_time");// 发车时间station.setLeave_time(leave_time);String arrived_time = jsonObject2.getString("arrive_time");// 到达时间station.setArrived_time(arrived_time);String lishi = jsonObject2.getString("lishi");// 历时station.setLishi(lishi);String erdengzuo = jsonObject2.getString("ze_num");// 二等座station.setZe_num(erdengzuo);String yingzuo = jsonObject2.getString("yz_num");// 硬座station.setYz_num(yingzuo);lists.add(station);}}}} catch (ClientProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (JSONException e) {e.printStackTrace();}return lists;}
