python - 怎么查找到天猫的cookie信息？

最近很痛苦啊，因为运行程序遭遇网页重定向的问题实在不懂怎么解决啊？
有人建议我可以使用带cookie登入网页，但是很天猫的cookie到底怎么找啊，找资料半天实在没结果，恳请大神细细讲解到底怎么查天猫的cookie的信息，真的是被搞疯了。
附上spider源码：

# -*- coding: utf-8 -*-
import scrapy
from topgoods.items import TopgoodsItem

class TmGoodsSpider(scrapy.Spider):
    name = "tm_goods"
    allowed_domains = ["http://www.tmall.com"]
    start_urls = (
        'https://list.tmall.com/search_product.htm?q=%C5%AE%D7%B0&type=p&spm=a220m.1000858.a2227oh.d100&from=.list.pc_1_searchbutton',
    )
    #记录处理的页数
    count=0 
     
    def parse(self, response):
          
        TmGoodsSpider.count += 1
        
        ps = response.xpath("//p[@id='J_ItemList']/p[@class='product']/p")
        if not ps:
            self.log( "List Page error--%s"%response.url )
              
        for p in ps:
            item=TopgoodsItem()
            #商品价格
            item["GOODS_PRICE"] = p.xpath("p[@class='productPrice']/em/@title")[0].extract()
            #商品名称
            item["GOODS_NAME"] = p.xpath("p[@class='productTitle']/a/@title")[0].extract()
            #商品连接
            pre_goods_url = p.xpath("p[@class='productTitle']/a/@href")[0].extract()
            item["GOODS_URL"] = pre_goods_url if "http:" in pre_goods_url else ("http:"+pre_goods_url)
            
            yield scrapy.Request(url=item["GOODS_URL"],meta={'item':item},callback=self.parse_detail,
            dont_filter=True)

    def parse_detail(self,response):

        p = response.xpath('//p[@class="extend"]/ul')
        if not p:
            self.log( "Detail Page error--%s"%response.url )
            
        item = response.meta['item']
        p=p[0]
        #店铺名称
        item["SHOP_NAME"] = p.xpath("li[1]/p/a/text()")[0].extract()
        #店铺连接
        item["SHOP_URL"] = p.xpath("li[1]/p/a/@href")[0].extract()
        #公司名称
        item["COMPANY_NAME"] = p.xpath("li[3]/p/text()")[0].extract().strip()
        #公司所在地
        item["COMPANY_ADDRESS"] = p.xpath("li[4]/p/text()")[0].extract().strip()
        
        yield item

结果：
