Python 刮皮多恩'；t显示每个链接，其数据以我自己的模式爬网

我有以下脚本：

#!/usr/bin/python 
from twisted.internet import reactor
import scrapy
from scrapy.crawler import CrawlerRunner
from scrapy.utils.log import configure_logging
from scrapy.selector import Selector
from lxml import html

class GivenSpider(scrapy.Spider):
    name = "dmoz"
    allowed_domains = ["dmoz.org"]
    start_urls = [
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/",
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/"
    ]

    def parse(self, response):
#       filename = response.url.split("/")[-2] + '.html'
        select = Selector(response)
        urls=GivenSpider()
        u=urls.start_urls
        titles = select.xpath('//a[@class="listinglink"]/text()').extract()
        print ' [*] Start crawling at %s ' % u
        for title in titles:
            print '\t %s' % title


#configure_logging({'LOG_FORMAT': '%(levelname)s: %(message)s'})
runner = CrawlerRunner()

d = runner.crawl(GivenSpider)
d.addBoth(lambda _: reactor.stop())
reactor.run()

输出为：

但是我想把每个爬网的url打印到正确的位置。像这样：

我如何在scrapy中处理它？

此信息在

响应中：

print ' [*] Start crawling at %s ' % response.url
