Ruby code for batch download of railscasts

Rails3 is coming out, and it's time to start learning. You can find a good tutorial on the Internet: http://railscasts.com/episodes, which can be downloaded.

Unfortunately, only 10 entries are displayed on each page and cannot be downloaded in batches. If you find the all episodes link in the right sidebar.

 

But there is no such thing. You can only click it one by one to see it. Carefully compare the two addresses

Http://railscasts.com/episodes/234-simple-form

Http://media.railscasts.com/videos/234_simple_form.mov

They found that there was a certain relationship between them, and they were ecstatic, so they had the following:Code

 
Require 'open-Uri 'Open ('HTTP: // railscasts.com/episodes/archive') Do | f | S = "F. each do | Line | S <Line End allurls = file. new (file. join ("C:", "railcastsvideourls.txt"), "W +") M =/href = "(\/episodes \/. +) "/URLs = S. scan (m) URLs. each {| x | begin allurls. puts X [0]. gsub (// episodes \ //, "http://media.railscasts.com/videos "). gsub (/-/,"_"). to_s + ". mov "end} allurls. closeend
 

 

Run the above code to get all the addresses to download. Of course, the premise is that you want to install Ruby. If you haven't installed Ruby, I will attach all the addresses! After finding the address, I believe everyone knows how to download it. You can write a ruby script to download it. Of course, I prefer thunder.
