python - 如何将 start_url 添加为项目？

Question

我是 Python 和 Scrapy 新手。我希望 item['Source_Website'] 成为我正在抓取的网址。我怎样才能实现这个目标？

我尝试了 item['Source_Website'] = selecter.ulr 和 item['Source_Website'] = start_urls 但没有运气。

from scrapy.selector import Selector
from scrapy.spider import BaseSpider
from shikari.items import ShikariItem

class Radiate (BaseSpider) :
  name = "sss"
  download_delay = 3
  concurrent_requests = 1
  allowed_domains = ["website.com"]
  start_urls = ['http://www.website.com/1',
                'http://www.website.com/2']

  def parse(self, response) :
    sel = Selector (response)
    item = ShikariItem ()
    item['Heading'] = str (sel.xpath ('//h1/text()').extract ())
    item['Source_Website'] = 
    return item

Answer 1

使用response.url如下:

item['Source_Website'] = response.url
