In Ruby, you can use the mechanism to batch download photos from the School Intranet,

You have nothing to do with it. You have used "machize" to create a code that can download photos of on-campus albums.

It's a little simple to write .... It mainly analyzes the user ID and album ID based on the album address, simulates the request to the album page, extracts all the photos, and downloads them to a local folder.

Ruby version: ruby1.8.7 or ruby1.9.2
Operating System: windows 7

I have not tried it in Linux ~ However, it should also be possible:

Copy codeThe Code is as follows:

@ Page = @ agent. get ('HTTP: // 3g.renren.com /')
@ Page = @ page. form_with (: method => 'post') do | r |
R. email = e
R. password = p
End. submit
