  http.request(req)

re_normal = /\<td\>([0-9-]*\.*\d*)\<\/td\>/im

content.scan(re_items) do |x,y|
  anchors = y.scan(re_anchor)
  puts "code: #{Iconv.iconv('utf-8', 'gb2312', anchors[0].to_s)}"
  puts "name: #{Iconv.iconv('utf-8', 'gb2312', anchors[1].to_s)}"
  puts "company: #{Iconv.iconv('utf-8', 'gb2312', anchors[2].to_s)}"
  normal = y.scan(re_normal)
  puts "date: #{normal[0]}"
  puts "util: #{normal[1]}"
  puts "total: #{normal[2]}"
  puts "rate: #{normal[3]}"
end

ruby版同样有字符编码的问题, 所以, 使用了Iconv来作转码.
