How to download files with Ruby

// Note: the "b" in "wb" in the open method may not be needed in
// non-Windows environments. In Windows it indicates that you're writing
// binary information. You probably won't need it for downloading straight text
// or html either.

require 'net/http'

Net::HTTP.start("static.flickr.com") { |http|
  resp = http.get("/92/218926700_ecedc5fef7_o.jpg")
  open("fun.jpg", "wb") { |file|
    file.write(resp.body)
   }
}
puts "Yay!!"

Download recent flickr pictures with ruby and the flickr api

// To make this work, you need to get your own flickr api key.
// Get one here: http://www.flickr.com/services/api/misc.api_keys.html
// Other than that, just plug and chug and have fun!
// The "b" in "wb" in the second open method may not be necessary in
// non-windows environments.

require 'open-uri'
require 'rexml/document'

open('http://www.flickr.com/services/rest/?method=flickr.photos.getRecent&api_key=YOUR_KEY_HERE') { |f|
    doc = REXML::Document.new f.read
    i = 0
    doc.elements.each("rsp/photos/photo") { |element|
        if i < 3
            open("images/file" << i.to_s << ".jpg", "wb").
                write(open("http://static.flickr.com/" << \
                element.attributes["server"] << "/" << \
                element.attributes["id"] << "_" << \
                element.attributes["secret"] << "_o.jpg").read)
        else
            break
        end
        i = i + 1
    }
}

puts "Done!"
