Reusing cookies
If you have stored the cookie from domain example.com
, these stored cookies can't be pushed through the webdriver session to any other different domanin e.g. example.edu
. The stored cookies can be used only within example.com
. Further, to automatically login an user in future, you need to store the cookies only once, and that's when the user have logged in with in the application after successful authentication. Before adding back the cookies you need to browse to the same domain from where the cookies were collected.
Demonstration using Selenium Python
As an example, you can store the cookies once the user have logged in within an application as follows:
from selenium import webdriver
import pickle
driver = webdriver.Chrome()
driver.get('http://demo.guru99.com/test/cookie/selenium_aut.php')
driver.find_element_by_name("username").send_keys("abc123")
driver.find_element_by_name("password").send_keys("123xyz")
driver.find_element_by_name("submit").click()
# storing the cookies
pickle.dump( driver.get_cookies() , open("cookies.pkl","wb"))
driver.quit()
Later at any point of time if you want the user automatically logged-in, you need to browse to the specific domain /url first and then you have to add the cookies as follows:
from selenium import webdriver
import pickle
driver = webdriver.Chrome()
driver.get('http://demo.guru99.com/test/cookie/selenium_aut.php')
# loading the stored cookies
cookies = pickle.load(open("cookies.pkl", "rb"))
for cookie in cookies:
# adding the cookies to the session through webdriver instance
driver.add_cookie(cookie)
driver.get('http://demo.guru99.com/test/cookie/selenium_cookie.php')
