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

The open method:

open("http://image.com/img.jpg")

is returning a Tempfile object, while encode64 expects a String.

Calling read on the tempfile should do the trick:

ActiveSupport::Base64.encode64(open("http://image.com/img.jpg") { |io| io.read })
