  $pagenNum=request('page');  $limit=request('limit');  $count=Admin::count();  $page=$pagenNum-1;   if ($page != 0) {    $page = $limit * $page;    $limit=$limit*$pageNum;   }  $data = Admin::offset($page)->limit($limit)->get()->toArray();  return response([   'code'=>'0',   'msg'=>'',   'count'=>$count,   'data'=>$data]);
