Ruby Mechanize：关注链接

在Ruby上的Mechanize中，我必须为每个新页面分配一个新变量。 例如：

page2 = page1.link_with(:text => "Continue").click page3 = page2.link_with(:text => "About").click ...etc 

有没有办法在没有变量保持每个页面状态的情况下运行Mechanize？ 喜欢

  my_only_page.link_with(:text => "Continue").click! my_only_page.link_with(:text => "About").click!

我不知道我是否正确理解了你的问题，但如果是动态循环并处理它们的问题，你可以这样做：

  require 'mechanize' url = "http://example.com" agent = Mechanize.new page = agent.get(url) #Get the starting page loop do # What you want to do on the page - ex. extract something... item = page.parser.css('.some_item').text item.save if link = page.link_with(:text => "Continue") # As long as there is still a nextpage link... page = link.click else # If no link left, then break out of loop break end end
