第一时间获取苹果官网IPad2供货信息

因为IPad2在官网 停止销售有一段时间。

有可能恢复供货也被抢购掉。（IPhone4 在今年2月份时 在官网抢购一台4999转手能卖到5700以上）

下面ruby代码 每半小时访问一次 苹果在线商店，如果货源信息变动，发邮件给指定联系人。

代码量很少，在这种小程序上ruby真的很方便~~

sevk 写道

发送gmail可以用 gem install gmail_sender
不用自己写代码的，方便。

      g = GmailSender.new('[e-mail]', 'password')
      #next unless File.exist? fn
      #g.attach(fn) # you can attach any number of files, but there are limits for total attachments size
      ti = now.strftime("%y-%m-%d")
      p g.send(:to => t, :subject => ti, :content => File.read(fn))

好的 谢谢 当时第一反应就是用smtp类来发 有没有支持很多邮箱的gem 支持飞信的gem
