download_files.rb

require 'net/http'
require 'net/ftp'
require 'uri'

def http_download_uri(uri, filename)
  puts "Starting HTTP download for: " + uri.to_s
  http_object = Net::HTTP.new("my_AWS_S3_bucket_url", 80)
  #http_object.use_ssl = true if uri.scheme == 'https'
  puts uri
  begin
    http_object.start do |http|
      request = Net::HTTP::Get.new uri
      http.read_timeout = 500
      http.request request do |response|
        open File.join("/", "Users","my_username","my_images", "my_image_name"), 'wb' do |io|
          response.read_body do |chunk|
            io.write chunk
          end
        end
      end
    end
  rescue Exception => e
    puts "=> Exception: '#{e}'. Skipping download."
    return
  end
  puts "Download success!"
end
