Ruby uses mechanize to bulk download Facebook photo _ruby topics

I have nothing to do, with Mechanize do a can download the campus photo album Code.

It's a little shabby .... The main is based on the address of the album to analyze the user ID and photo album ID, and then simulate the request album page, and extract all the photos, and then download to a local folder.

Ruby version: ruby1.8.7 or ruby1.9.2
Operating system: Windows 7

Linux has not tried ~ but should also be able to:

Copy Code code as follows:

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", "Start analyzing album Address ...")
Begin
user_id,album_id = Parse_album_uri (Album_link)

Puts Iconv.conv ("gb2312", "Utf-8", "Your album address is incorrect, please re-enter!") ")

Page.links_with (: href =>/http:\/\/3g\.renren\.com\/album\/wgetphoto\.do?/). Each do |link|
