Ruby Mechanize：点击链接

在 Mechanize on Ruby 中，我必须为我访问的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

有没有一种方法可以在不使用保存每个页面状态的变量的情况下运行 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你的问题，但如果这是动态循环大量页面并处理它们的问题，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
