自己闲来无事,用mechanize做了一个可以下载校内相册照片的代码
写的有些简陋。。。。主要是根据相册的地址来分析用户ID和相册ID,然后模拟请求相册页面,并提取所有照片,然后下载到本地的一个文件夹中
ruby版本:ruby1.8.7 or ruby1.9.2
操作系统:windows 7
linux下没有试过~不过应该也可以的- #encoding: utf-8
- require 'rubygems'
- require 'mechanize'
- class Renren
- def initialize(e,p)
- @agent = Mechanize.new
- @page = @agent.get('http://3g.renren.com/')
- @page = @page.form_with(:method => 'POST') do |r|
- r.email = e
- r.password = p
- end.submit
- end
- def fetch_other_photo(album_link,foldername)
- photo_urls = []
- puts Iconv.conv("gb2312", "utf-8", "开始分析相册地址.....")
- begin
- user_id,album_id = parse_album_uri(album_link)
- rescue
- puts Iconv.conv("gb2312", "utf-8", "您的相册地址不正确,请重新输入!")
- return
- end
- page = @agent.get("http://3g.renren.com/album/wgetalbum.do?id=#{user_id}&owner=#{album_id}")
- puts Iconv.conv("gb2312", "utf-8", "正在获取所有照片地址.....")
- loop do
- page.links_with(:href => /http:\/\/3g\.renren\.com\/album\/wgetphoto\.do?/).each do |link|
- photo = link.click
- photo_urls << photo.link_with(:text => "下载该图").href
- end
- break if page.link_with(:text => "下一页").nil?
- page = page.link_with(:text => "下一页").click
- end
- if photo_urls.length > 0
- puts Iconv.conv("gb2312", "utf-8", "开始下载相册.....")
- unless File.directory?("#{foldername}")
- Dir.mkdir("#{foldername}")
- end
- Dir.chdir("#{foldername}") do |path|
- photo_urls.each do |photo_url|
- @agent.get(photo_url) do |photo|
- puts Iconv.conv("gb2312","utf-8","正在保存文件#{photo.filename}……已经下载#{((photo_urls.index(photo_url)+1).to_f/photo_urls.length*100).to_i}%")
- photo.save
- end
- end
- end
- puts Iconv.conv("gb2312","utf-8","相册下载完毕.....")
- else
- puts Iconv.conv("gb2312","utf-8","相册内没有照片哟~")
- end
- end
- private
- def parse_album_uri(uri)
- uri = uri.chomp("#thumb")
- uri = uri.split("?")
- if uri.length > 1 and uri[1].include?("owner")
- uri = uri[1].split("&")
- user_id = uri[0].split("=")[1]
- album_id = uri[1].split("=")[1]
- else
- uri = uri[0].split("/")
- album_id = uri[4]
- user_id = uri[5].split("-")[1]
- end
- return user_id,album_id
- end
- end
- print Iconv.conv("gb2312","utf-8","用户名:")
- username = gets.chomp()
- print Iconv.conv("gb2312","utf-8","密码:")
- password = gets.chomp()
- renren = Renren.new(username,password)
- loop do
- print Iconv.conv("gb2312","utf-8","粘贴相册地址:")
- uri = gets.chomp()
- renren.fetch_other_photo(uri, username)
- print Iconv.conv("gb2312","utf-8","按0退出程序,按其它键继续下载其它相册:")
- break if gets.chomp() == "0"
- end
