scrapy python Request is not defined

问题

i found an answer here:

code

for site in sites:
            Link = site.xpath('a/@href').extract()
            CompleteLink = urlparse.urljoin(response.url, Link)
            yield Request(Link, callback = self.parseOneCar)

I got this exception

exceptions.NameError: global name 'Request' is not defined

what should I import please?
