Cron命令在给定的URL上运行控制器功能？

I have a route i.e Route::get('abc/xyz', 'AbcController@xyz'). How to write a cron command in cpanel to execute the controller function xyz()?

And the xyz() function is accepting a request i.e xyz(Request $r){if($_REQUEST['step']=='1'){...}}

Cron job option & Command in cpanel :

05 16 * * * wget http://www.abc.in/laravelAppFolder/abc/xyz?step=1

How to write the above command correctly to run the controller function?
