use Illuminate\Http\Request;

我在自己的接口 里面 引入 use Illuminate\Http\Request;
提示 ： FatalErrorException in Resign.php line 10:
Declaration of App\Http\services\register\Resign::logic(Illuminate\Http\Request $request) must be compatible with App\Http\services\common\Inter::logic()

代码：
//控制器调用接口。

  use App\Http\services\register\Resign;
              $reg =new Resign();
              $reg->logic();

//接口。
<?php

 namespace App\Http\services\register;
 use App\Http\model\register\sign;
 use App\Http\services\common\Inter;
 use App\Http\services\common\Demo;
 use Illuminate\Http\Request;
class Resign extends Demo implements Inter{
        public function logic(Request $request){
                      dd($request->all());
        }
}

?>
请问 怎么解决。谢谢！
