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;

public class Train {
private String trainno; //车次
private String type; //类型
private String departstation; //始发站
private String terminalstation; //终点站
private String station; //经过站
private String endstation; //目的站
private String starttime; //开始时间
private String endtime; //结束时间
private String costtime; //历时
private String day; //所用天数

private String gr; //高级软卧
private String qt; //其他
private String rw; //软卧
private String rz; //软座
private String td; //特等座
private String wz; //无座
private String yw; //硬卧
private String yz; //硬座
private String ed; //二等座
private String yd; //一等座
private String sw; //商务座

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() {
return station;
}
public void setStation(String station) {
this.station = station;
}
public String getEndstation() {
return endstation;
}
public void setEndstation(String endstation) {
this.endstation = endstation;
}
public String getStarttime() {
return starttime;
}
public void setStarttime(String starttime) {
this.starttime = starttime;
}
public String getEndtime() {
return endtime;
}
public void setEndtime(String endtime) {
this.endtime = endtime;
}
public String getCosttime() {
return costtime;
}
public void setCosttime(String costtime) {
this.costtime = costtime;
}
public String getDay() {
return day;
}
public void setDay(String day) {
this.day = day;
}
public String getGr() {
return gr;
}
public void setGr(String gr) {
this.gr = gr;
}
public String getQt() {
return qt;
}
public void setQt(String qt) {
this.qt = qt;
}
public String getRw() {
return rw;
}
public void setRw(String rw) {
this.rw = rw;
}
public String getRz() {
return rz;
}
public void setRz(String rz) {
this.rz = rz;
}
public String getTd() {
return td;
}
public void setTd(String td) {
this.td = td;
}
public String getWz() {
return wz;
}
public void setWz(String wz) {
this.wz = wz;
}
public String getYw() {
return yw;
}
public void setYw(String yw) {
this.yw = yw;
}
public String getYz() {
return yz;
}
public void setYz(String yz) {
this.yz = yz;
}
public String getEd() {
return ed;
}
public void setEd(String ed) {
this.ed = ed;
}
public String getYd() {
return yd;
}
public void setYd(String yd) {
this.yd = yd;
}
public String getSw() {
return sw;
}
public void setSw(String sw) {
this.sw = sw;
}

}


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;
}
