All I want to do is respond with a base64 string when this action on my controller is contactacted.
class V1::AppProxyController < ApplicationController
def logo
send_file("#{Rails.root}/public/fresh_modal.png",
type: "image/png",
disposition: "inline")
end
But the response, when I put it into an online converter, does not return the image. Plus it has all those odd characters. What am I doing wrong?
"�PNG

CodePudding user response：
You need to encode the file to Base64 instead of returning the binary data
File.open("#{Rails.root}/public/fresh_modal.png", 'rb') do |img|
base64_file = 'data:image/png;base64,' Base64.strict_encode64(img.read)
end
render plain: base64_file
