Ruby Implementation page Image capture _ruby topic

Some time ago to see a lot of people write the next sister script, I also write a

Module Commonhelper
 
 require ' Nokogiri '
 require ' Open-uri '
 
 def down_load_xmz
  site_url = ' http:// Www.xxx.com "for
 
  index_page in 1..141
   doc_html = nokogiri::html (open (site_url+ '/share/comment-page-' +index_ page.to_s)
   doc_html.css ("#comments p img"). Each do |item_img|
    Puts Item_img[:src]
    download_img (ITEM_IMG[:SRC]) end end
 
 ####### #下载图片
 def Download_img (img_url)
  begin
   Img_file = open (img_url) {|f| F.read}
   file_name = Img_url.split ('/'). Last
   #puts file_name
   Open ("public/meizi/" +file_name, "WB") {|f| f.write (img_file)} return
   "/public/meizi /"+file_name
  rescue => err
   puts err return
   "
