scrapy parse中的item在遍历的时候无法和自定义方法中的item关联

	    def parse(self, response, **kwargs):
        item = TuiqiuspiderproItem()
        # item = response.meta['item']
        resp = response.json()
        articles = resp['articles']
        for article in articles:
            if article['is_video'] is False and compTime(article['published_at']):
                item['title'] = article['title']
                item['publish_time'] = article['published_at']
                item['source_href'] = article['share']
                item['tag'] = resp['label']
                data = scrapy.Request(url=article['share'], callback=self._article, meta={'item': item}, dont_filter=False)
                data.meta['item'] = item
                yield data

    def _article(self, response):
        item = response.meta['item']
        soup = BeautifulSoup(response.text, 'lxml')
        comments = soup.findAll(text=lambda text: isinstance(text, Comment))
        [comment.extract() for comment in comments]
        try:
            article = soup.find("div", {"class": "news-left"})
            tips = article.find('p', {"class": "tips"}).find_all('span')
            if tips and len(tips) > 1:
                item['author'] = tips[1].get_text()
            else:
                item['author'] = tips[0].get_text()
            self.saveImages(article)
            # del article_pc.find('div', {'class': 'con'}).find("div").attrs['style']
            item['content'] = str(delattrs(article.find('div', {'class': 'con'}))).replace(
                "data-src", "src")
        except Exception as e:

        author = response.xpath('.//div[@class="news-left"]/p[@class="tips"]/span/text()').extract_first()
        item['author'] = author
        # item['content'] = response.xpath('.//div[@class="con"]').extract_first()
        yield item
