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. I tried (practically guessed) this:
ActiveSupport::Base64.encode64(open("http://image.com/img.jpg")) But I get this error:
TypeError: can't convert Tempfile into String from /usr/lib/ruby/1.8/base64.rb:97:in `pack' from /usr/lib/ruby/1.8/base64.rb:97:in `encode64' from (irb):19 from :0

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. By consisting only of ASCII characters, base64 strings are generally url-safe, and that's why they can be used to encode data in Data URLs.
The URL encoding is the same as Basic encoding the only difference is that it encodes or decodes the URL and Filename safe Base64 alphabet and does not add any line separation. String encodedURL = Base64.
To encode a file:
require 'base64' Base64.encode64(File.open("file_path", "rb").read) To produce the file from the encoded string:
require 'base64' encoded_string = Base64.encode64(File.open("file_path", "rb").read) File.open(file_name_to_create, "wb") do |file| file.write(Base64.decode64(encoded_string)) end If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
