通过UI自动化获取登录成功后的cookies存入Excel中再从Excel读取cookies实现自动登录

一、通过driver.get_cookies()将获取到的cookies存到Excel中，最主要使用到Excel的写入xlwd和xlrd模块的函数；

from selenium import webdriver
import time
import xlwt
import os
driver = webdriver.Chrome()
driver.get('https://www.cnblogs.com/')
driver.implicitly_wait(30)
# 实战
# 1.把cookies写到Excel中，
# 写一次（name,value,path,domain,httpOnle,
# secure 前面四个是cookies里面必须的值，暂时我们取这四个）
# 思考：写那些数据，Excel怎么设计？
# 使用什么工具写Excel---》xlwt
#      怎么写？
#准备Excel
#准备workbook
workbook = xlwt.Workbook(encoding='utf-8')
#创建一个workbook
worksheet = workbook.add_sheet('cookies')
#写入excel
#参数和值对应，Excel的表头
worksheet.write(0,0,label = 'name')
worksheet.write(0,1,label = 'value')
worksheet.write(0,2,label = 'path')
worksheet.write(0,3,label = 'domain')
worksheet.write(0,4,label = 'httpOnly')
worksheet.write(0,5,label = 'secure')


#获取cookies 手动操作，获取cookies
time.sleep(40)
cookies = driver.get_cookies()
for cookie in cookies:
    print(cookie)

for i in range(1,len(cookies)+1):   #1,2,3,4,5,6
    worksheet.write(i, 0, label=cookies[i-1]['name'])
    worksheet.write(i, 1, label=cookies[i-1]['value'])
    worksheet.write(i, 2, label=cookies[i-1]['path'])
    worksheet.write(i, 3, label=cookies[i-1]['domain'])
    worksheet.write(i, 4, label=cookies[i-1]['httpOnly'])
    worksheet.write(i, 5, label=cookies[i-1]['secure'])

current_path = os.path.dirname(__file__)
cookies_path = os.path.join(current_path,'../data/cookies.xlsx')
workbook.save(cookies_path)
print('Cookies save !!')


# 二.后面执行，就只需要写Excel中

import xlrd
import os
from selenium import webdriver
import time
#实战2
driver = webdriver.Chrome()
driver.get('https://www.cnblogs.com/')
driver.implicitly_wait(30)
#打开excel
current_path = os.path.dirname(__file__)
cookies_path = os.path.join(current_path,'../data/cookies.xlsx')
workbook = xlrd.open_workbook(cookies_path)
sheet01 = workbook.sheet_by_index(0)
cookies_list = []
#获取表格中的cookies并放到cookies_list里面
for i in range(1,sheet01.nrows):
    cookie_dic={}
    cookie_dic['name'] = sheet01.cell_value(i,0)
    cookie_dic['value'] = sheet01.cell_value(i, 1)
    cookie_dic['path'] = sheet01.cell_value(i, 2)
    cookie_dic['domain'] = sheet01.cell_value(i, 3)
    cookie_dic['httpOnly'] = bool(sheet01.cell_value(i, 4))
    cookie_dic['secure'] = bool(sheet01.cell_value(i, 5))
    cookies_list.append(cookie_dic)

#将列表中的cookies放到cookies中
for cookie in cookies_list:
    driver.add_cookie(cookie)

time.sleep(3)
driver.refresh()
