Laravel 5 - How to passing request data from route to controller

I am new in laravel, How to passed request data into controller ? Just like happen on view ?

Route::get('/kelihatan', function (Request $request) {
    return view( 'pages' , [ 'page' => 'index' , '_request' => $request->all() ] );
});

How to passing request data to controller before passed into view or model ? Just like this ??

Route::get( '/{page}', 'UserController@show' );
