How to implement file download in laravel?

Question

Laravel

I get an error 500 (if I put in the controller , then everything outputs fine, but the download does not work). controller:return '123';

public static function downdload(Request $request) {
        $file = public_path(). $_POST['link'];

        return Storage::download($file);
    }

Ajax:

$('.this-block a').click(function() {
        $.ajax({
            url: '/ajax/download',
            type: 'POST',
            data: {
                link: $(this).data('link'),
                _token: "<?php echo csrf_token(); ?>"
            },
            success: function( data ) {   
            }
        });
    });
