Usually I implement file uploads over a REST API by allowing clients to send a PUT request with the base64 encoded binary data of the file inside the request body.

Then you can route the client request to your CarrierWave uploader, which can decode the binary data contained in the request body using something like FilelessIO.new(Base64.decode64(encoded_file))

Does this stands still if we're not talking about image files? Say a pdf or a .docx file. Does base64 encoding of a such files is still possible? – Sebastialonso Aug 27 '15 at 15:44
@Sebastialonso yes, you should be able to base64 a PDF or DOCX file as well – jonfaulkenberry Aug 28 '15 at 19:31

Basically it is based on the tool which is used by the API consumer. If API consumer is using ruby then can consume it by passing File object, or using httmultiparty gem we can upload the file.

For you reference https://github.com/jwagener/httmultiparty. Please let me know if you need more help.

SO, there is no universal tool for all kind of consumers? – Avdept Jun 04 '14 at 21:19

Try RestClient. It encapsulates net/http with cool features like multipart form data:

require 'rest_client'
RestClient.post('http://localhost:3000/foo', 
  :name_of_file_param => File.new('/path/to/file'))

It also supports streaming.

gem install rest-client will get you started.
