ssl

namespace MyApp\Http\Middleware;

use Closure;

class HttpsProtocol {

public function handle($request, Closure $next)
{
if (!$request->secure() && env('APP_ENV') === 'prod') {
return redirect()->secure($request->getRequestUri());
}

return $next($request); 
}
}
Then, apply this middleware to every request adding, setting the rule at Kernel.php file, like so:

protected $middleware = [
'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
'Illuminate\Cookie\Middleware\EncryptCookies',
'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
'Illuminate\Session\Middleware\StartSession',
'Illuminate\View\Middleware\ShareErrorsFromSession',

// appending custom middleware 
'MyApp\Http\Middleware\HttpsProtocol'

];
