How do I get the files I uploaded in laravel?

Seems really basic right, until you see that I use Super Agent to upload my files:

  onDrop(files) {
    var req = request.post('//' + location.hostname + '/api/v1/blogs/image/upload').set('X-CSRF-TOKEN', $('meta[name="csrf-token"]').attr('content'));

    files.forEach((file)=> {
        req.attach(file.name, file);
    });

    req.end((data) => {
      console.log(data);
    });
  }

When I inspect the request object coming back:

[

As you can see the file name could be anything so I can't just do: $request->hasFile('photo')

Any ideas on how to handle this situation?
