下面是我的蜘蛛的代码,
class Blurb2Spider(BaseSpider):
name = "blurb2"
allowed_domains = ["www.domain.com"]
def start_requests(self):
yield self.make_requests_from_url("http://www.domain.com/bookstore/new")
def parse(self, response):
hxs = HtmlXPathSelector(response)
urls = hxs.select('//div[@class="bookListingBookTitle"]/a/@href').extract()
for i in urls:
yield Request(urlparse.urljoin('www.domain.com/', i[1:]),callback=self.parse_url)
def parse_url(self, response):
hxs = HtmlXPathSelector(response)
print response,'------->'
在这里,我想在href链接与基础链路相结合,但我得到了下面的错误,
exceptions.ValueError: Missing scheme in request url: www.domain.com//bookstore/detail/3271993?alt=Something+I+Had+To+Do
任何人都可以让我知道为什么我收到此错误以及如何加入基本的URL与HREF链接,并产生一个请求
