航空网站航班查询自动点击提醒器

前段时间国际飞机票非常难买，所以做了个小程序自动点击来监控机票网站(东方航空)的刷新。（虽然最后也没有刷到票，不过学习了一下简单的爬虫知识和发邮件的代码，改写后还能为自己使用，挺不错的）。
依赖环境：selenium,chrome driver,smtplib

用selenium中的by_css_selector来做的。在chrome中按F12进入开发者模式，有个小鼠标，将小鼠标对准某个元素，显示的蓝色字体部分就是css的定位码。 有时候网速太慢，需要通过sleep来提供足够的加载等待时间。
随后用smtplib来发邮件。（注意设置的代理邮箱里面需要设置POP3/SMTP服务的权限）
