Get file name using widget binary-link

Hi guys, I use a widget binary-link in a new view, and I need to get a file name of the upload file to do other process with it. I have been checked RestService @path « upload » and MetaFiles class but what is the best way to get it.
Thanks a lot for your time.
Best regards.

You must create a new Axelor module (your own) or if you already have your own, you don’t need.
Use injection with Guice to bind on the RestService, do your own behavior and call the normal behavior with super.

Thanks for your answer @PHPierre, it´s a little complicated to me, but I´ll try to do it. For now I have resolved saving into the database. Isn´t the best way. Thank you a lot again.
