使用阿里云火车票查询接口案例——CSDN博客

首先我们需要一个实体类，专门放火车票信息的封装类，实体类：

Train.java:

 /**  
* @Title: Train.java
* @Package cn.bdqn.guanMingSys.entity
* @Description: TODO该方法的主要作用：
* @author A18ccms A18ccms_gmail_com  
* @date 2017-7-11 下午11:24:15
* @version V1.0  
*/
package cn.bdqn.HomeSys.entity;

 /**   
 *    
 * 项目名称：GuangMingSys   
 * 类名称：Train   
 * 类描述：   火车票的实体类

public class Train {
	private String trainno;               //车次
	private String type;                  //类型

	public String getTrainno() {
		return trainno;
	}
	public void setTrainno(String trainno) {
		this.trainno = trainno;
	}
	public String getType() {
		return type;
	}
	public void setType(String type) {
		this.type = type;
	}
	public String getDepartstation() {
		return departstation;
	}
	public void setDepartstation(String departstation) {
		this.departstation = departstation;
	}
	public String getTerminalstation() {
		return terminalstation;
	}
	public void setTerminalstation(String terminalstation) {
		this.terminalstation = terminalstation;
	}
	public String getStation() {

	}
	public String getEndtime() {

	}
	public void setEndtime(String endtime) {
		this.endtime = endtime;
	}
	public String getCosttime() {

	}
	public void setCosttime(String costtime) {

	}
	public String getDay() {
		return day;
	}
	public void setDay(String day) {
		this.day = day;
	}
	public String getGr() {

	}
	public void setGr(String gr) {

	}
	public String getQt() {

}

然后我们把解析出来的json格式数据存放在实体类里面：

   /**
	 * 
	* @Title: getTaicket
	* @Description: 该方法的主要作用：按照出发站与终点站获取车票信息
	* @param   设定文件  
	* @return  返回类型：void   
	* @throws
	 */
	public String getTaicket()
	{
		 String path = "/train/ticket";
		    Map<String, String> headers = new HashMap<String, String>();
		    //最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
		    headers.put("Authorization", "APPCODE " + appcode);
		    Map<String, String> querys = new HashMap<String, String>();
		    querys.put("date",startDate);
		    querys.put("end",endAddress );
		    querys.put("start", startAddress);

		    	HttpResponse response=null;
				try {
					response = HttpUtils.doGet(host, path, method, headers, querys);
				} catch (Exception e1) {
					// TODO 异常执行块！
					e1.printStackTrace();
				}
		    	String result=null;
				try {
					result = EntityUtils.toString(response.getEntity());
				} catch (ParseException e) {
					// TODO 异常执行块！
					e.printStackTrace();
				} catch (IOException e) {
					// TODO 异常执行块！
					e.printStackTrace();
				}
		    	JSONObject json = JSONObject.fromObject(result);
				if (json.getInt("status") != 0) {
					System.out.println(json.getString("msg"));
				} else {
					//JSONObject resultarr = json.optJSONObject("result");
					JSONArray resultarr = json.optJSONArray("result");
					for (Object obj : resultarr) {
						//將json转换成list集合
						jsonList = JSONArray.toList(resultarr,Train.class);
					}
					
		    }
		    return SUCCESS;
