需要忽略基本http认证

Question

我无法获得页面源代码。

require 'mechanize' 

    agent = Mechanize.new   
    page = agent.get("https://#{ip}/") 

末有错误：

/home/lord/.gem/ruby/1.9.1/gems/mechanize-2.4/lib/mechanize/http/agent.rb:682:in `response_authenticate': 401 => Net::HTTPUnauthorized for https://82.144.208.6/cgi-bin/welcome.cgi -- no credentials found, provide some with #add_auth -- available realms: r722 (Mechanize::UnauthorizedError) 
from /home/lord/.gem/ruby/1.9.1/gems/mechanize-2.4/lib/mechanize/http/agent.rb:288:in `fetch' 
from /home/lord/.gem/ruby/1.9.1/gems/mechanize-2.4/lib/mechanize.rb:407:in `get' 
from /home/lord/ruby/ruby_backup/backup-done.ru:35:in `block (2 levels) in <main>' 

我怎么能忽略HTTP认证，并获得源？ thx

该异常包含页面存取器。该文档描述它：http://mechanize.rubyforge.org/Mechanize/ResponseCodeError.html

尝试：

begin 
    page = agent.get ... 
rescue Mechanize::ResponseCodeError => e 
    page = e.page 
end
