How to encode media in base64 given URL in Ruby

Question

I\'m trying to upload an image to PingFM. Their documentation says:

media – base64 encoded media data.

I can access this image via the URL.

Answer 1

This will work too, it's a little cleaner

 require 'base64'

 Base64.encode64(open("file_path").to_a.join)

"How do you decode this back into a file?" - @user94154

 require 'base64'

 open('output_file_name.txt', 'w') do |f| 
   f << Base64.decode64( encoded_content )
 end

Where encoded_content would be the previously encoded file content return value.
