ruby 用watir 登录 CU的代码

require 'rubygems'
require 'watir'
url_logout="http://bbs.chinaunix.net/member.php?mod=logging&action=logout"
url_login="http://bbs.chinaunix.net/member.php?mod=logging&action=login&logsubmit=yes"
ie = Watir::IE.new
ie.goto(url_logout)
ie.goto(url_login)

ie.text_field(:name,"username").set("test")
ie.text_field(:name,"password").set("pass")
ie.button(:name,"loginsubmit").click

url="http://bbs.chinaunix.net/forum-141-1.html"
ie.goto(url)

感觉不如python 的 cookielib 、urllib 和 urllib2 的方式好
