Python 3.5.2 和 Python 3.6.0 都试了，都报错:

https://kyfw.12306.cn/otn/lcxxcx/query 返回403

[SunYong0821]

是因为火车站的地址变了，而且不止这一个问题，即使换了地址，返回的jason有问题
地址：https://kyfw.12306.cn/otn/leftTicket/query?leftTicketDTO.train_date=2017-4-30&leftTicketDTO.from_station=GZQ&leftTicketDTO.to_station=HCQ&purpose_codes=ADULT

json返回：
validateMessagesShowId: "_validatorMessage",
status: true,
httpstatus: 200,
data: [
{
queryLeftNewDTO: {
train_no: "650000K7950D",
station_train_code: "K795",
start_station_telecode: "GGQ",
start_station_name: "广州东",

但是get回来的status是false，导致下面的data不显示，怎么办

[liopoos]

查询返回的地址变了，并且返回的json数据也变了。
请求的url应该是：

url = 'https://kyfw.12306.cn/otn/leftTicket/query?leftTicketDTO.train_date={}&leftTicketDTO.from_station={}&leftTicketDTO.to_station={}&purpose_codes=ADULT'.format(
        date, from_station, to_station
)

json返回的数据：

{
    "validateMessagesShowId": "_validatorMessage",
    "status": true,
    "httpstatus": 200,
    "data": {
        "result": [

            "QHK": "青岛北"
        }
    },
    "messages": [],
    "validateMessages": {}
}

应返回的字典为：
available_trains = r.json()['data']['result']

火车时刻信息如下：

requests加请求头

现在查询上海到北京的列车，返回的json字符串是这样的，不知道该怎么改代码。那一串加密字符串该怎么弄呢？
