继承自 Apicontroller 的 API 控制器，是不是不能通过中间件做用户权限验证？

我如下操作之后 接口就不响应了

        return $this->myPaginate($ads);

        $name = $request['name'];
        $content = $request['content'];
        $href = $request['href'];
        $img = $request['img'];
        if (!$this->isValid($img)) {
            return response('请上传封面图~', 201);
        }
        if (!$this->isValid($name)) {
            return response('请填写标题~', 201);
        }
        if (!$this->isValid($content)) {

        }

        $ad = Advertisement::create(['name' => $name, 'content' => $content, 'href' => $href, 'img' => $img]);
        if ($ad) {
