What information about device does cookie store?

I'm using selenium to collect cookies, and here's the question: does cookies store information about selenium?

回答1:

You can check the cookies list by driver.manage().getCookies(); Return type is Set <Cookies>.

Hope this will help.

No, cookies doesn't store information about Selenium.

Demonstration

A simple example to demonstrate the information stored by cookies using pickle is as follows:

Code Block:

import pickle
import selenium.webdriver 
import time

driver = selenium.webdriver.Firefox()
driver.get("http://www.google.com")
pickle.dump( driver.get_cookies() , open(r'C:\Utility\testdata\my_cookies.pickle',"wb"))
driver.quit()
pickle_off = open(r'C:\Utility\testdata\my_cookies.pickle',"rb")
personOut = pickle.load(pickle_off)
print(list(personOut))

Console Output:
