Laravel5.2 升级到 5.4 Validator 报错

class StoreCommentRequest extends Request
{
    public function rules()
    {
        return [
            'article_id' => 'integer',
        ];
    }

    public function message()
    {
        return [
            'article_id' => '找不到对应文章',
        ];
    }

    public function attributes()
    {
        return [
            'article_id' => '文章ID',
        ];
    }
}
public function store(StoreCommentRequest $request)
    {
            $validator = Validator::make(request()->all(), [
                'article_id' => 'required|integer',
            ]);
            if ($validator->fails()) {
                $errors = $validator->errors();

                return JSend::error('参数出错');
            }
        }

同时使用StoreCommentRequest和Validator::make()会报错store函数改为以下代码就好了
报错信息：{
"message": "The given data failed to pass validation.",
"file": "\/vendor\/laravel\/framework\/src\/Illuminate\/Foundation\/Http\/FormRequest.php:125",
"code": 500
}

 public function store(Request $request)
    {
    $validator = Validator::make(request()->all(), [
                'article_id' => 'required|integer',
            ]);
            if ($validator->fails()) {
                $errors = $validator->errors();

                return JSend::error('参数出错');
            }
    }

这个问题原因是啥？咋解决
