scrapy过滤不起作用

class HuanqiuSpider(CrawlSpider):

    allowed_domains = ['tech.huanqiu.com']
    start_urls = ['https://tech.huanqiu.com/internet']
    
    rules = (
        Rule(LinkExtractor(allow=(r"article", )), callback='parse_item', follow=False),
    )
    
    def parse_item(self, response):
        title = response.xpath("//div[@class='t-container-title']/h3/text()").extract_first()
        url = response.url
        print(title, url)
        p_list = response.xpath('//article/section/p')
        if p_list:
            content = '\n'.join([p.xpath('.//text()').extract_first() for p in p_list])        
            #print(content)

爬取结果最后两个不理解，为什么allowed_domains和rules过滤不起作用
