python自动查询12306余票并提醒 python自动查询12306余票并发送邮箱提醒脚本
一枚空指针 人气:0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:
