Python reptile - Selenium (12) for login Cookies, Cookies automatically log in and add

WebDriver provides related methods of operation Cookie, you can read, add, and delete cookie information, the following will explain respectively 模拟登陆并获取Cookies, 添加Cookies自动登录two small examples.

The key method used in this chapter as follows:

• get_cookies(): Get all the cookie information.

• get_cookie(name): Returns a dictionary key for the "name" of the cookie information.

• add_cookie(cookie_dict): Add cookie. "Cookie_dict" refers to a dictionary object, you must have the name and value value.

• delete_cookie(name,optionsString): Delete cookie information. "Name" is the name of the cookie you want to delete, "optionsString" is the cookie option, currently supported options include the "path", "field."

• delete_all_cookies(): Delete all cookie information.

1, simulated landing and get Cookies

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get('https://www.baidu.com/')

# 模拟登陆
driver.find_element_by_link_text('登录').click()
time.sleep(2)
driver.find_element_by_xpath('//*[@id="TANGRAM__PSP_10__footerULoginBtn"]').click()
time.sleep(2)
driver.find_element_by_name("userName").send_keys("账号")
driver.find_element_by_name("password").send_keys("密码")
driver.find_element_by_xpath('//*[@id="TANGRAM__PSP_10__submit"]').click()
time.sleep(20) #可能会出现验证码，手动点一下

# 获取cookies
cookies = driver.get_cookies()
print(cookies)
driver.quit()

2, add the automatic logon Cookies

Note:

1. Cookies get when each dictionary field is not uniform, add all will complain, so I just added a few more important field.
2. The list code field into cookies on step acquisition of content, or build your own.

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get('https://www.baidu.com/')
time.sleep(2)
cookies = [] #换成上一步获取的Cookies
for cookie in cookies:
    driver.add_cookie(
        {
            'domain':cookie['domain'],
            'name': cookie['name'],
            'value':cookie['value'],
            'path': cookie['path']
        }
    )
# # 刷新页面
driver.refresh()

# driver.quit() #为方便查看，页面就不关了
