I noticed that Laravel 5 doesn't have a secure (https) filter so i have re-implemented it in the form of a middleware, i hope that you find this useful.
- Add 
Secure.phpto yourapp\Http\Middlewaredirectory. - Add the secure middleware to your route.
 
- If you are using route annotations, don't forget to rescan your routes using the 
php artisan route:scancommand. - The redirect is disabled in any non-production environment (as you likely won't have acquired a certificate at this stage).
