How to allow Binary File download using GRAPE API

Question

I want to allow downloading a binary file (.p12 file) using ruby\'s Grape API. This is what I am trying.

Answer 1

There are issues #412 and #418 have been reported to grape github page. Which are related to return a binary file and override content type.

To return binary format like so:

get '/download_file' do
    content_type "application/octet-stream"
    header['Content-Disposition'] = "attachment; filename=yourfilename"
    env['api.format'] = :binary
    File.open(your_file_path).read
end
