如何获取包含Ruby上所有对象的HTML页面

你可以使用 mechanize 做这项工作:

require "rubygems"
require "mechanize"

url = "http://stackoverflow.com/"
agent = WWW::Mechanize.new
page = agent.get(url)


page.search('img[@src]').each do |image|
  src = image["src"]
  image_file = agent.get(src) if src
  # Store image_file data it in database ...  
end

page.search('link[rel="stylesheet"]').each do |css|
  src = css["src"]
  css_file = agent.get(src) if src
  # Store css_file data it in database ...  
end

page.search('script[type="text/javascript"]').each do |script|
  src = script["src"]
  script_file = agent.get(src) if src
  # Store script_file data it in database ...    
end

您仍然需要处理异常并使用相关的SRC属性修复资源。但这应该能完成任务。但是,此解决方案不会获取样式表中引用的图像。
