大多是url或者start_url格式问题。。
以下格式供参考:
start_urls = ['http://irm.cninfo.com.cn/ircs/interaction/allQuestionsForSzse.do']
def parse(self, response): item = 0 func_dict = {"0": self.parser_html} url = "http://irm.cninfo.com.cn/ircs/interaction/allQuestionsForSzse.do" yield scrapy.Request(url, callback=func_dict[str(0)])
