Bobby老师：
我的 parse函数是如下写的，但是运行时进步了parse_question函数，我尝试了带cookies、headers和在headers中加refer，都没成功，求指教问题出在哪里？谢谢

def parse(self, response):
    cookie_dict = response.meta.get("cookies","")
    all_urls = response.css("a::attr(href)").extract()
    all_urls = [urljoin(response.url,url) for url in all_urls]
    all_urls = filter(lambda x:True if x.startswith("https") else False,all_urls)
    for url in all_urls:
        match_obj = re.match("(.*zhihu.com/question/(\d+))(/|$).*",url)
        if match_obj:
            request_url = match_obj.group(1)
            question_id = match_obj.group(2)

            self.headers["referer"] = url

            yield scrapy.Request(request_url,headers=self.headers,callback=self.parse_question,cookies=cookie_dict)
            break

def parse_question(self,response):
    pass
