Ruby实现网页图片抓取（中韩女足第二场比赛）这样也行？

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
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 ”
end
end

end
