• 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 Filespython37python.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()))
    

     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': 1599101956, 'httpOnly': False, 'name': '_gid', 'path': '/', 'secure': False, 'value': 'GA1.2.1722891321.1599015556'}, {'domain': '.cnblogs.com', 'expiry': 1662087556, 'httpOnly': False, 'name': '_ga', 'path': '/', 'secure': False, 'value': 'GA1.2.276388436.1599015556'}]

    删除所有cookies,查看cookies:[]

    六、cookie操作的几个方法

    1.get_cookies():获取所有cookies

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

    3.清除指定cookie:delete_cookie()

    4.delete_all_cookies():清除所有cookies

    5.add_cookie(cookie_dict):添加cookie的值
