瀏覽器頭部信息

#對反爬蟲網頁，可以設置一些headers信息，模擬成瀏覽器取訪問網站
import urllib.request
url="https://www.baidu.com/"
file=urllib.request.urlopen(url)
# print('獲取當前url:',file.geturl() )
# print('file.getcode,HTTPResponse類型:',file.getcode )
print('file.info 返回當前環境相關的信息：' ,file.info())

cookie 獲取一

# 導入模塊
from selenium import webdriver

driver = webdriver.Chrome(executable_path='D:\chromedriver\chromedriver')

url = "https://www.baidu.com"
driver.get(url)
# 獲取cookie列表
cookie_list = driver.get_cookies()
# 格式化打印cookie
# print(cookie_list)
cookie_dict = {}
cookie = ''
for cookie in cookie_list:
    cookie_dict[cookie['name']] = cookie['value']
print(cookie_dict)

driver.quit()

 cookie 獲取二

import requests
def Get_Cookie(url):
    session = requests.Session()
    headers = {
        'user-agent': 'Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1'
    }
    req = session.get(url, headers=headers, verify=True)
    # 獲取當前的Cookie
    Cookie = dict(session.cookies)
    # print(Cookie)
    return Cookie

cookie = ''
coo = Get_Cookie('https://www.baidu.com/')
# print(coo)
for index, key in enumerate(coo):
    cookie = cookie + (key + '=' + coo[key] + ';')
    # print(coo[key])
print(cookie)

 cookie 獲取三

# python3.6環境
from urllib import request
from http import cookiejar

if __name__ == '__main__':
    # 聲明一個CookieJar對象實例來保存cookie
    cookie = cookiejar.CookieJar()
    # 利用urllib.request庫的HTTPCookieProcessor對象來創建cookie處理器,也就CookieHandler
    handler = request.HTTPCookieProcessor(cookie)
    # 通過CookieHandler創建opener
    opener = request.build_opener(handler)
    # 此處的open方法打開網頁
    response = opener.open('https://blog.csdn.net/t8116189520/article/details/80319339')
    # 打印cookie信息
    for item in cookie:
        print('Name = %s' % item.name)
        print('Value = %s' % item.value)
