How to handle received file and json data together?

Hi,

My client(android) call a route with post that handle this with multipart library to send a request to server.

In this route need to upload image inside of json data(image and json together)

When I read Request or request()->all() or $_REQUEST I can see json parameters, but when I read File or $_FILE, I see binary data(just 0,1 and not file parameters)

What should I do? I don't like to read image as code and encode it again, I want to get file as file.
