4、自定义cookieHandler发送请求

from urllib import request
# 导入需要引用cookie的包
from http import cookiejar
import urllib.parse
# 请求的url
url = "http://www.jinri.com"
# 请求的头文件
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36"
}
# 创建请求对象
req = request.Request(url,headers = headers)
# 创建cookie
cookie = cookiejar.CookieJar()
# 兼容火狐浏览器
# cookie = cookiejar.MozillaCookieJar()
# 创建cookie处理对象
cookieHandler = request.HTTPCookieProcessor(cookie)
# 创建opener
opener = request.build_opener(cookieHandler)
# 发送请求
response = opener.open(req)
# 打印cookie
for item in cookie:
    print('Name = %s' % item.name)
    print('Value = %s' % item.value)
