Laravel 5 how to validate route parameters?

Question

I want to validate the route parameters in the "form request" but don't know how to do it.

Below is the code sample, I am trying with:

Route

// controller Server
Route::group(['prefix' => 'server'], function(){
    Route::get('checkToken/{token}',['as'=>'checkKey','uses'=> 'ServerController@checkToken']);
});

Controller

namespace App\Http\Controllers;


use App\Http\Controllers\Controller;

use Illuminate\Http\Request;
use App\Http\Requests;


class ServerController extends Controller {

public function checkToken( \App\Http\Requests\CheckTokenServerRequest $request) // OT: - why I have to set full path to work??
    {

        $token = Token::where('token', '=', $request->token)->first();      
        $dt = new DateTime; 
        $token->executed_at = $dt->format('m-d-y H:i:s');
        $token->save();

        return response()->json(json_decode($token->json),200);
    }
}

CheckTokenServerRequest

namespace App\Http\Requests;

use App\Http\Requests\Request;

class CheckTokenServerRequest extends Request {

    //autorization

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {

        return [
            'token' => ['required','exists:Tokens,token,executed_at,null']
        ];
    }

}

But when I try to validate a simple url http://myurl/server/checkToken/222, I am getting the response: no " token " parameter set.

Is it possible to validate the parameters in a separate "Form request", Or I have to do all in a controller?

ps. Sorry for my bad English.

For \App\Http\Requests\CheckTokenServerRequest you can add use App\Http\Requests\CheckTokenServerRequest; at the top.
If you pass the token by url you can use it likes a variable in controller.

public function checkToken($token) //same with the name in url
{

    $_token = Token::where('token', '=', $token)->first();      
    $dt = new DateTime; 
    $_token->executed_at = $dt->format('m-d-y H:i:s');
    $_token->save();

    return response()->json(json_decode($token->json),200);
}
