用ruby写了一个简单的Gmail登陆和获取未读邮件(http协议)

主要是为了学习一下mechanize,没有用imap或者pop3,

require 'rubygems'
require 'mechanize'

agent = WWW::Mechanize.new

page = agent.get 'http://www.gmail.com'
form = page.forms.first
form.Email = 'YOUR GMAIL ACCOUNT'
form.Passwd = 'YOUR GMAIL PASSWORD'
page = agent.submit form

page = agent.get page.uri.to_s.sub(/\?.*$/, "?ui=html&zy=d")

page.search("//tr[@bgcolor='#ffffff']")  do |row|
  from, subject = *row.search("//b/text()")
  url = page.uri.to_s.sub(/\?.*$/, row.search("/td:eq(2)//a").first.attributes["href"])
  puts "From: #{from}\nSubject: #{subject}\nLink: #{url}\n\n"
  email = agent.get url
  puts email.search("//div[@class='msg']/")
  puts "\n\n"
end

试了一下，什么输出都没有。
