scrapy獲取目標cookie

python2.7代碼實現：
爬蟲主文件：

# -*- coding: utf-8 -*-
import sys
from scrapy.http import Request

#python語言轉碼，非必要
reload(sys)
sys.setdefaultencoding("utf-8")

import scrapy

#定義爬蟲類，必須繼承scrapy.Spider
class DmozSpider(scrapy.Spider):
    name = "itcast"	#設置爬蟲名稱
    header = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'}	#設置瀏覽器用戶代理
    
    #用start_requests()方法,代替start_urls
    def start_requests(self):
        return [Request('https://www.baidu.com',meta={'cookiejar':1},callback=self.parse)]
    
    #parse回調函數
    def parse(self, response):
        Cookie = response.headers.getlist('Cookie')	#獲取響應cookie
        print 1111111111111111111111
        print Cookie
        print 1111111111111111111111
        return 0
