Selenium3+python3自动化（二十八）--cookie相关操作

前言

虽然cookie相关操作在平常ui自动化中用得少，偶尔也会用到，比如登录有图形验证码，可以通过绕过验证码方式，添加cookie方法登录。

登录后换账号登录时候，也可作为后置条件去删除cookie然后登录下个账号

一、获取cookies：get_cookies()

1.获取cookies方法直接用:get_cookies()

2.先启动浏览器，获取cookies，打印出来发现是空：[]

3.打开博客首页后，重新获取cookies，打印出来，就有值了

# coding:utf-8
from selenium import webdriver
import time
driver=webdriver.Chrome()
print("打开浏览器后，查看cookie结果：{}".format(driver.get_cookies()))
driver.get("http://www.cnblogs.com/canglongdao/")
print("访问canglongdao博客园，查看cookie结果：{}".format(driver.get_cookies()))

 运行结果：

打开浏览器后，查看cookie结果：[]
访问canglongdao博客园，查看cookie结果：[{'domain': '.cnblogs.com', 'expiry': 1599099565, 'httpOnly': False, 'name': '_gid', 'path': '/', 'secure': False, 'value': 'GA1.2.506249297.1599013166'}, {'domain': '.cnblogs.com', 'expiry': 1662085165, 'httpOnly': False, 'name': '_ga', 'path': '/', 'secure': False, 'value': 'GA1.2.1600623487.1599013166'}]

　二、登录后的cookies

1.先登录博客园（需要改成自己的账号和密码）

2.重新获取cookies，发现跟之前获取的不一样了

3.主要是找到这一个cookie，发现它的name和value发生了变化，这就是未登录和已登录的区别了

{'domain': '.cnblogs.com', 'expiry': 1600309421, 'httpOnly': True, 'name': '.Cnblogs.AspNetCore.Cookies', 'path': '/', 'secure': False, 'value': 'CfDJ8K5MrGQfPjpFvRyctF-QEQdlqzhqG6PZtQKQrvpGfVSWEsJhfqznqKwPW7PWGQMy3IhudpppvC4A0Im_RwQofGzos_48A6w'}

注意：登录有时需要拖动滑块拼图，这里可以添加等待时间time.sleep(n),然后手动拼图

# coding:utf-8
from selenium import webdriver
import time
driver=webdriver.Chrome()
print("打开浏览器后，查看cookie结果：{}".format(driver.get_cookies()))
driver.get("http://www.cnblogs.com/canglongdao/")
print("访问canglongdao博客园，查看cookie结果：{}".format(driver.get_cookies()))
driver.get("https://account.cnblogs.com/signin?returnUrl=https:%2F%2Fwww.cnblogs.com%2F")
driver.find_element_by_id("mat-input-0").send_keys("333@qq.com")
driver.find_element_by_id("mat-input-1").send_keys("P@ssw0rd")
driver.find_element_by_xpath("//div[@class='ng-tns-c141-2 ng-star-inserted']/button[@mat-flat-button='']").click()
time.sleep(6)
driver.maximize_window()
print("登录博客园，查看cookie：{}".format(driver.get_cookies()))

　　运行结果：

"D:\Program Files\python37\python.exe" E:/study/selenium_study/a825.py
打开浏览器后，查看cookie结果：[]
访问canglongdao博客园，查看cookie结果：[{'domain': '.cnblogs.com', 'expiry': 1599099813, 'httpOnly': False, 'name': '_gid', 'path': '/', 'secure': False, 'value': 'GA1.2.759010773.1599013414'}, {'domain': '.cnblogs.com', 'expiry': 1662085413, 'httpOnly': False, 'name': '_ga', 'path': '/', 'secure': False, 'value': 'GA1.2.431778497.1599013414'}]
登录博客园，查看cookie：[{'domain': '.cnblogs.com', 'expiry': 1662085423, 'httpOnly': False, 'name': '__gads', 'path': '/', 'secure': False, 'value': 'ID=bf09a693c7fead68-2206974f46c3000f:T=1599013423:S=ALNI_Mbqvosrdrq3rE8h9uzctpVTVeZAyw'}, {'domain': '.cnblogs.com', 'expiry': 1600309421, 'httpOnly': True, 'name': '.CNBlogsCookie', 'path': '/', 'secure': False, 'value': '5ABD8FE57A40B86EB5095482D6627EE7D7EAD13656D017453A1DABA697DB8C69C692DF5E0C7EBC8F00EAE603DB51AC3C712038DC65ECB12E192C3EB9E3802AA769D4F36D500540A8F830BEC1A8F1A082D5047DCF'}, {'domain': '.cnblogs.com', 'expiry': 1599013481, 'httpOnly': False, 'name': '_gat', 'path': '/', 'secure': False, 'value': '1'}, {'domain': '.cnblogs.com', 'expiry': 1600309421, 'httpOnly': True, 'name': '.Cnblogs.AspNetCore.Cookies', 'path': '/', 'secure': False, 'value': 'CfDJ8K5MrGQfPjpFvRyctF-QEQdlqzhqG6PZtQKQrvpGfVSWEsJhfqznqKwPW7PWGQMy3IhudpppvC4A0Im_RwQofGzos_48A6wx5y2chNOYJIdkq4wJ60YOvvlIbQJrfaUX5GU3VZ4UitneBpy4e-ZEiRT66JWkw80quUxS9xgQhdRgTaKfdpTQ7iIoiMLuLL9NNFBi07rctOb9LjsgsQu9u9wV7bHSfnSkZjmDT49SJpSvvbQA1KsQ1NPgLPoXd3gumEdZFL7OrpTp_bATBmlfIMqrwb_Y_Ue6707qeUN2gqQacWjC4jBMlwJpRyyt74ygZ3VHaB0jn7seWwbfEJ2-sT-eBk4ylve_8wLEFaN2W0uUNgr7BKxBIglWjDzyQ-k3Ulm9WYE9-JAY8keedhjcigAHsdtnK2PxawNCIfjQEASgUUELpfExIdQPybR6wg0TD_GIaXGR0Lm_fErU9KtdbxO4reSscwhkN5PV8tPMGSgUuuCQdNjXDb--73vtXYytHB1xXbx12sd4hJ-PvfTrhp2EAh0LblvBCQ_e2BvPopwjE2gzQZg'}, {'domain': '.cnblogs.com', 'expiry': 1599099821, 'httpOnly': False, 'name': '_gid', 'path': '/', 'secure': False, 'value': 'GA1.2.759010773.1599013414'}, {'domain': '.cnblogs.com', 'expiry': 1662085421, 'httpOnly': False, 'name': '_ga', 'path': '/', 'secure': False, 'value': 'GA1.2.431778497.1599013414'}]

Process finished with exit code 0

　三、获取指定name的cookie:driver.get_cookie(name)

1.获取cookies发现里面有多个cookie，有时候我们只需要其中的一个，把重要的提出来，比如登录的cookie

2.这里用get_cookie(name)，指定对应的cookie的name值就行了，比如博客园的:.Cnblogs.AspNetCore.Cookies

# #获取指定name的cookie
print(driver.get_cookie(name=".Cnblogs.AspNetCore.Cookies"))　　

　四、清除指定cookie: delete_cookie()

1.为了进一步验证上一步获取到的就是登录的cookie，可以删除它看看页面什么变化

2.删除这个cookie后刷新页面，发现刚才的登录已经失效了，变成未登录状态了

# #清除指定name的cookie
driver.delete_cookie(name=".Cnblogs.AspNetCore.Cookies")

print("删除部分cookie，查看cookies:{}".format(driver.get_cookies()))
driver.refresh()　　

 五、清除所有cookies: delete_all_cookies()

1.清除所有cookies后登录状态也失效了，cookies为空[]　

# #清除所有cookies
driver.delete_all_cookies()

 参考代码：

# coding:utf-8
from selenium import webdriver
import time
driver=webdriver.Chrome()
print("打开浏览器后，查看cookie结果：{}".format(driver.get_cookies()))
driver.get("http://www.cnblogs.com/canglongdao/")
print("访问canglongdao博客园，查看cookie结果：{}".format(driver.get_cookies()))
driver.get("https://account.cnblogs.com/signin?returnUrl=https:%2F%2Fwww.cnblogs.com%2F")
driver.find_element_by_id("mat-input-0").send_keys("333@qq.com")
driver.find_element_by_id("mat-input-1").send_keys("P@ssw0rd")
driver.find_element_by_xpath("//div[@class='ng-tns-c141-2 ng-star-inserted']/button[@mat-flat-button='']").click()
time.sleep(6)
driver.maximize_window()
print("登录博客园，查看cookie：{}".format(driver.get_cookies()))
#获取指定name的cookie
# print(driver.get_cookie(name=".CNBlogsCookie"))
print(driver.get_cookie(name=".Cnblogs.AspNetCore.Cookies"))
#刷新页面
driver.refresh()
time.sleep(2)
#清除指定name的cookie
# driver.delete_cookie(name=".CNBlogsCookie")
driver.delete_cookie(name=".Cnblogs.AspNetCore.Cookies")

print("删除部分cookie，查看cookies:{}".format(driver.get_cookies()))
driver.refresh()
time.sleep(2)
#清除所有cookies
driver.delete_all_cookies()
print("删除所有cookies，查看cookies:{}".format(driver.get_cookies()))
