python实现扫描论坛回帖,自动发附件(应对求种之类的)

背景:

笔者因为需要在 www.kindle114.com 上分享一些图书,鉴于各种网盘神马的,都会把涉及版权的分享给失效了,总是换分享连接很麻烦,所以不得已只能通过邮件来传播知识,这就需要每天去看回帖的邮箱,一一发送,甚是麻烦。用一个python的脚本去扫描这些页面,把邮箱地址抓出来后自动发送才是懒人应该做的事情。

 

实现过程:

需要用crontab来实现每天定时执行这个脚本。

脚本一共分三部分:

1. 遍历指定帖子的所有回帖页,抓取Email格式的字符串,遇到某些情况就终止扫描

2. 比对过去发送过的列表,如果是新出现的则加入发送列表中

3. 将发送列表用python的email功能发送出去,并且带上附件

 

可以改进的地方:

1. 记录下每次扫描的终点,下次从这个位置扫描,避免重复扫描的浪费

2. 将URL和附件做成字典,可以灵活发送

3. 做成一个在线系统来维护这个数据和列表

 

注意点:

1. python的sendmail,发送列表要用list类型的

2. 如果是QQ邮箱,要把邮箱的独立密码去掉(我也不知道如果不去掉应该怎么去验证),否则会出现验证失败的错误

3. 可能有人会因为隐私原因,把邮箱地址写成怪怪的样子,那我就没辙了...

4  本文只是抛砖引玉,论坛形式千变万化,需要灵活修改脚本来实现网页抓取

5. 鉴于现在出版物粗糙的太多了,所以想先预览一下合情合理。如果觉得电子书或者视频有价值,请去电影院看电影或购买正版书籍,写这个短短文章都需要花费时间和精力,何况是写书和拍片,人家就是靠这个谋生。
