    if(&#39;GET&#39; != $request->method()){
      $input = $request->all();
      $log = new OperationLog(); # 提前创建表、model
      $log->uid = $user_id;
      $log->path = $request->path();

      $log->save();  # 记录日志
    }
    return $next($request);
  }

protected $middlewareGroups = [
    'web' => [
      ...
      \App\Http\Middleware\AdminOperationLog::class,
      ...
    ],
    'api' => [
