接口简介：
火车车次经停站点查询，调用该接口必须先调用火车票余票信息查询接口，根据余票查询接口返回的数据来查询车次经停站点。可作为余票查询的补充查询。
请求地址：
https://cn.apihz.cn/api/12306/api3.php
请求方式：
POST或GET。
请求参数：
【名称】【参数】【必填】【说明】
【用户ID】【id】【是】【用户中心的数字ID，例：id=10000000】
【用户KEY】【key】【是】【用户中心通讯秘钥，例：key=15he5h15ty854j5sr152hs2】
【车次编号】【train_order】【是】【车次编号，查询余票接口返回的车次唯一编号。例：train_order=76000G328609】
【cookie】【ck】【否】【不传该参数则使用平台提供的cookie，如果多次查询失败可能是平台cookie失效，可传自己的cookie，参照图片教程：https://down.erguanmingmin.com/api/img/12306ck.png，浏览器访问12306官网，打开调试模式，然后任意查询火车票，找到该链接https://kyfw.12306.cn/otn/leftTicket/queryU，取cookie里面的JSESSIONID值，只需传等号后面的字符串即可。ck=0EC5DA0C04CB6793F9C293EBF28B485B】
返回参数：
【名称】【参数】【说明】
【状态码】【code】【200成功，400错误。普通用户采用接口本地线路调用，成功率无保障。彩钻和炫钻用户采用本地+代理双模式调用，成功率超高。查询成功后的信息有60秒缓存期。】
