最近想爬虫抓一下 andrew chen 的博客 http://andrewchen.co/recent/ 页面上都有，唯一的问题就是没有日期... 想试试邮件订阅，然后从邮箱来试试抓一下内容，通过发送日期得到每篇的时间
可以，找一下 POP3 的实现就行了，比如 Ruby 内置的： http://ruby-doc.org/stdlib-2.1.0/libdoc/net/pop/rdoc/Net/POP3.html
require 'net/pop'
pop = Net::POP3.new('pop.example.com')
pop.start('YourAccount', 'YourPassword') # (1)
if pop.mails.empty?
puts 'No mail.'
else
i = 0
pop.each_mail do |m| # or "pop.mails.each ..." # (2)
File.open("inbox/#{i}", 'w') do |f|
f.write m.pop
end
m.delete
i += 1
end
puts "#{pop.mails.size} mails popped."
end
pop.finish # (3)
- Call #start and start POP session.
- Access messages by using #each_mail and/or #mails.
- Close POP session by calling #finish or use the block form of start.
如果要找第三方库，或许这个可以考虑： https://github.com/mikel/mail#getting-emails-from-a-pop-server
