如何在python scrapy中带cookie进行访问？，pythonscrapy,简单的通过scrapy访

简单的通过scrapy访问雪球都报错，我知道要先访问一次雪球，需要cookie信息才能真正打开连接。scrapy据说可以不用在意cookie，会自动获取cookie。我按照这个连接在middleware里已经启用cookie，http://stackoverflow.com/ques...，但为什么还是会返回404错误？搜索了几天都没找到答案。郁闷啊，求帮忙给个简单代码如何访问，谢谢了

class XueqiuSpider(scrapy.Spider):    name = "xueqiu"    start_urls = "https://xueqiu.com/stock/f10/finmainindex.json?symbol=SZ000001&page=1&size=1"    headers = {        "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",        "Accept-Language": "zh-CN,zh;q=0.8",        "Connection": "keep-alive",        "Host": "www.zhihu.com",        "Upgrade-Insecure-Requests": "1",        "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36"    }    def __init__(self, url = None):        self.user_url = url    def start_requests(self):        yield scrapy.Request(            url = self.start_urls,            headers = self.headers,            meta = {                'cookiejar': 1            },            callback = self.request_captcha        )    def request_captcha(self,response):        print response
