用浏览器登录然后ruby / mechanize接管它？

这有可能吗？ 我需要传递给机械化的东西？ 我可以用什么url开始呢？

我无法管理（到目前为止）使用机械化登录到一个网站，所以我想我是否可以做这个小小的解决方法。 我相信我可以捕获所有的cookie和其他所有内容，然后将它传递给ruby / mechanize来完成剩下的工作……

下面的截图是使用firebug进行的（ Firebug记录POST或GET请求，响应头 ）

登录工作=只有一行

和登录的html工作

 
 
 
User Name
 
Password
 
 
 
 
 
  Save?     
 
 
   

登录对我不起作用

这是HTML

 
 
 
Members Login
 
 Username  
 
 Password  
 
 
 
Forgot your password?
 
  

在这两种情况下，我的脚本几乎都是一样的。

 require 'rubygems' require 'mechanize' #agent = WWW::Mechanize.new agent = WWW::Mechanize.new page = agent.get("http://www.vbulletin.org/forum/index.php") login_form = page.form_with(:action => 'login.php?do=login') puts login_form.fields.each { |f| puts "#{f.name} : #{f.value}" } login_form['vb_login_username'] = 'user name' login_form['vb_login_password'] = '' page = agent.submit login_form output = File.open("login.html", "w") {|f| f.write(page.parser.to_html) } 

用于登录的机械化日志不起作用

Answer 1

是的，捕获cookie（例如，通过Firefox中的FireCookies插件），并手动将其传递给机械化可能适用于大多数情况。

Answer 2

您的问题很可能源于Mechanize仅跟踪使用Set-Cookie HTTP标头创建的cookie。 它无法处理JavaScript创建的cookie。
