将价值动态传递给Spider-Scrapy

Question

我正在尝试将值动态传递给我的Spider以便抓取页面。当我执行它显示错误，并且不会继续。让我知道我的代码有什么问题。

class MyItem(Item):
url=Field()
title=Field()

class someSpider(CrawlSpider):
   name = 'crawlim'
   sitename=''
   items=[]

   def __init__(self, *args, **kwargs):
      urls = kwargs.pop('urls', []) 
      domains=kwargs.pop('domains',[])
      if domains:
        self.allowed_domains=domains.split(',')
      if urls:
        self.start_urls = urls.split(',')
      self.logger.info(self.start_urls)
      someSpider.rules=(Rule(LxmlLinkExtractor(allow=(),unique=True), callback='parse_obj', follow=True),)
      super(someSpider, self).__init__(*args, **kwargs)

错误消息：
