由于车票难抢，有时需要的车票已经售空，而我们需要捡漏，便可使用这个脚本。

具体实现了，自动查询某一车票的余票数量，当数量产生变化时，将自动发送QQ邮件到对于的邮箱进行提醒。

其中，发送邮箱的部分详情可参考我上一篇博文：Python 发送邮件 (smtp) QQ邮箱

脚本使用了python + selenium + chrome webdriver，需要先配置好三者的环境。

具体使用时候，需自行改变代码中的

邮箱信息、出发站、到达站、车次、日期、以及到相应查询页面中找到对应车票的html id：

在相应查询页面中按F12，弹出开发者模式，点击按钮，再点击对应车票的框，，，复制相应的id号到代码中对应处。

代码如下：
