Example Backend for Signed Uploads (ruby)

In the latest release. We have changed from a 'get' request to a 'post' request due to this request being blocked by many WAF's/Firewalls. This means you'll need to change you signature endpoint to a 'post' and potentially change how the params are unpacked.

example of backend process to create signature for signing uploads to cloudinary. The params will need to be turned into a hash in order to work with Cloudinary's sdk.

Check cloudinary documentation for more information on signing uploads, generating signatures and the various language specific SDK's available for this process.

This example is from their ruby SDK

  def generate_signature
    render json: Cloudinary::Utils.api_sign_request(params[:params_to_sign]to_unsafe_hash, ENV['CLOUDINARY_SECRET'])
  end
