How to upload file in casperjs without using fill related methods -

I have a file upload functionality that is not in any form.

  & lt; Input type = "file" id = "file_uploader" & gt;  

How do I write a Casparus script to check uploads?

Note: About the fill method, casperjs can control file uploads inside a file, except me uploadFile phantomjs . In fact, I'm looking for a provision that will upload files using the API's using the API's without the use of API methods.
