How to save and load cookies using Python + Selenium WebDriver

Question

How can I save all cookies in Python's Selenium WebDriver to a .txt file, and then load them later?

The documentation doesn't say much of anything about the getCookies function.

Answer 1

You can save the current cookies as a Python object using pickle. For example:

import pickle
import selenium.webdriver

driver = selenium.webdriver.Firefox()
driver.get("http://www.google.com")
pickle.dump( driver.get_cookies() , open("cookies.pkl","wb"))

And later to add them back:

import pickle
import selenium.webdriver

driver = selenium.webdriver.Firefox()
driver.get("http://www.google.com")
cookies = pickle.load(open("cookies.pkl", "rb"))
for cookie in cookies:
    driver.add_cookie(cookie)
