概述
上一篇写了12306的自动登录破解验证图https://blog.csdn.net/weixin_38283159/article/details/86498159
这篇算是它的后续部分加上了简单的刷票和预订功能，毕竟登录一下没什么实际价值嘛
博主曾被黄牛挣过一百大洋至今还耿耿于怀，不清楚他们到达是如何抢票的，我能想到的简单方案就是不断的刷新判断了…
效果图（自动登录部分gif见上篇）
思路就是用selenium模拟我们买票的流程，所以就不详细说了
代码
说明：代码只处理了二等座（一等座也适用，EF位置不能选），和无需选位置的（关于硬卧等类型是否能够选上下铺我也不知道）

两点说明
1、代码中使用的code.json外部文件获取见https://blog.csdn.net/weixin_38283159/article/details/86490978
中的trainService.py 中crawlCodeMess方法
2、如果登录图片验证失败，在十秒内可以手动点击验证图让程序继续下去
写在最后
刚接触selenium，一边查一边写，应该有很多不规范和漏洞，欢迎指正
