scrapy 里面这样传parameters可以吗？

Question

 def parse_item(self,response):
        item = pencilnewsItem()
        title_list=response.xpath('//div[@class=“article_content”]/h3/a/text()').extract()
        link_list=response.xpath('//div[@class=“article_content”]/h3/a/@href').extract()
        for link in link_list:
            item['link']=link
            yield scrapy.request(url=link,callback=self.parse_time_url(),dont_filter=True,meta=item)
    def parse_time_url(self,response):
        item=response.meta['item']
        item['time']=response.xpath('//div[@class= “article_create_time”]/span/text()').extract()

        yield item
