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

        divs = response.xpath("//div[@id='J_ItemList']/div[@class='product']/div")
        if not divs:
            self.log( "List Page error--%s"%response.url )

        for div in divs:
            item=TopgoodsItem()
            #商品价格
            item["GOODS_PRICE"] = div.xpath("p[@class='productPrice']/em/@title")[0].extract()
            #商品名称
            item["GOODS_NAME"] = div.xpath("p[@class='productTitle']/a/@title")[0].extract()
            #商品连接
            pre_goods_url = div.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):

        div = response.xpath('//div[@class="extend"]/ul')
        if not div:
            self.log( "Detail Page error--%s"%response.url )

        item = response.meta['item']
        div=div[0]
        #店铺名称
        item["SHOP_NAME"] = div.xpath("li[1]/div/a/text()")[0].extract()
        #店铺连接
        item["SHOP_URL"] = div.xpath("li[1]/div/a/@href")[0].extract()
        #公司名称
        item["COMPANY_NAME"] = div.xpath("li[3]/div/text()")[0].extract().strip()
        #公司所在地
        item["COMPANY_ADDRESS"] = div.xpath("li[4]/div/text()")[0].extract().strip()

        yield item

结果:

请仔细的讲解怎么找天猫的cookie,非科班出生编程的我,实在是太小白了

除了使用fiddler之外,也可以直接在浏览器里找到cookie。登录天猫,打开你要访问的页面,按f12,找到network,再找到你需要查看的url,右侧点击cookie,就能看到了。

1. 在浏览器里登陆 天猫的账号

2. 登陆成功后, 使用Fiddler捕获你在浏览网页里的HTTP请求.

3. 在请求头中找到 Cookie 节点, 它后面的内容就是你所需要的数据了.


因为 天猫 使用的是HTTPS协议, 所以想在Fiddler中看到HTTPS的数据的话, 需要做如下操作:

1. Tools -> Fiddler Options

2. HTTPS -> Decrypt HTTPS traffic .

在点了 Yes 之后会再次出来一个提示框, 选择 Yes

之后再点
