NotFoundHttpException in RouteCollection.PHP line 161:

这是我的代码,请帮我弄清楚错误
在我看来 ：

{{ link_to_route('deleteFile','Delete',[$file->resid]) }}

在路线：

Route::get('/deleteFile/{$id}',['as'=>'deleteFile','uses'=>'FilesController@deleteFile']);

并在控制器中：

class FilesController extends Controller{
public function deleteFile($id)
    {

         $file = Resource::find($id);
      Storage::delete(config('app.fileDestinationPath').'/'.$file->filename);
        $file->delete();
        return redirect()->to('/upload');
    }}

这是我的型号代码：

namespace App;

use Illuminate\Database\Eloquent\Model;

class Resource extends Model
{

    protected $table='resource';
    public $fillable=['resname'];
}
