  悲催的12306,彻底沦为各路抢票软件的服务提供方。元旦伊始,纯粹12306官网及APP抢票,愈一周的时间,仅到手一张凌晨3:55回家的站票。为远离脑残,无奈选择抢票软件,预购年后返沪车票。BTW,研究一下抢票脚本的实现思路,参考:(https://juejin.im/post/5b116504f265da6e0636cbc2 - Python3.6实现12306火车票自动抢票)。

  在原作者之上,对执行代码做了以下处理:

  1. 删除短信/邮件通知功能
  2. 删除控制台输入功能
  3. 新增登陆cookie的刷新
  4. 新增多车次抢票
  5. 新增多座位类型抢票

  注:使用 splinter.browser 在调用时,注意将 chrome驱动路径(chromedriver.exe所在)配置在环境变量 -  path 下。

代码如下:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from splinter.browser import Browser
from time import sleep
import sys

class BrushTicket(object):
    """买票类及实现方法"""
    def __init__(self, passengers, from_time, from_station, to_station, number_seat):

            num = use[0]

            seats_use = seats.split(‘,‘)
