用 mechanize 登录怎么处理跳转

jt_today — Mon, 29 Oct 2012 20:41:32 +0800

require 'rubygems'
require 'mechanize'

agent = Mechanize.new
page = agent.get("https://example.com/login")
login_form = page.forms.first
login_form.username = 'username'
login_form.password = 'password'
page = agent.submit(login_form)
pp page

代码如上。可是登录后有个跳转页，显示的是

#<Mechanize::Page
 {url #<URI::HTTPS:0xb6c5e764 URL:https://example.com/takelogin.php>}
 {meta_refresh #<Mechanize::Page::MetaRefresh "" "index.php">}
 {title nil}
 {iframes}
 {frames}
 {links}
 {forms}>

新手请教怎么处理这个跳转页

(Solved) 用 mechanize 出现问题。。似乎是 mechanize 没装对

版本 Ubuntu 12.04，ruby 1.8.7，gem 1.8.15 首先我sudo gem install mechanize --no-ri --no-rdoc 似乎结果不错

然后写了第一个程序

require 'rubygems'
require 'mechanize'

agent = Mechanize.new

运行一下就报错

./mechanize.rb:4: uninitialized constant Mechanize (NameError)
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `require'
    from mechanize.rb:2

这是什么原因呐
