Convert picture to binary BASE64

Question

How do I convert a picture to binary BASE64 and send it by post to another API to be saved?

It looks something like:

1. User imports a photo through the HTML form and it transforms it to binary BASE64 code:

    base64_encode = Base64.encode64(img_from_fild_form) 

2. The data is sent to another API (media):

    options = { :auth_key=>01qw6, :post_id=>20, :base64_encode=>base64_encode } HTTParty.post('localhost:9000/save_image', options) 

Answer 1

if the input is from a rails form then it probably as easy as:

Base64.encode64(params[:key_for_file].read)

the uploaded file is likely an instance of ActionDispatch::Http::UploadedFile

Answer 2

It should be as easy as:

require 'base64'
base64_encoded = Base64.encode64(img_from_file_form)

Hope that helps. :)
