Interactive fog session: how to get a bunch of signed URLs for European buckets with fog 0.4.1

gistfile1.rb

require 'active_support/time'
bucket = AWS.directories.select {|d| d.key == 'my_bucket'}
files = bucket.files.select {|f| f.content_length > 0 &&
  f.key =~ %r{client-name.*\.zip}}
expiration = Time.now.next_month.end_of_month
signed_urls = files.map {|f| f.url(expiration)}
fixed_signed_url = signed_urls.map do |su|
  su.sub(%r{s3\.(.*)/my_bucket}, "my_bucket.s3.#{$1}")
end
