Selenium Chromedriver add cookie - invalid domain error

Question

I am trying to store and upload a cookie that I retrieve from a webpage via selenium.

I am new to cookies so please tell me what I am doing wrong. I am trying to learn.

I open a page up with selenium, manually log in, peform some action then wait.. (and my code is set to get cookies after 30 seconds )

print "adding cookies now"
cookies = pickle.load(open("cookies.pkl", "rb"))
for cookie in cookies:
    driver.add_cookie(cookie)

after that, my cookies.pkl file looks something like this:

(lp0
(dp1
Vdomain
p2
V.twitter.com
p3
sVsecure
p4
I00
sVvalue
p5
V"v3:1484006785862560132892059"
p6
sVexpiry
p7
F1531267585.126113
sVpath
p8
# more lines

after this log_in_and_store() , i try to reopen the page with selenium while loading this cookies. If done correctly, it should open to the page i left off! Not the login page.

When I try uploading my cookies to the webpage like this:

driver.get('http://www.website.com')
cookies = pickle.load(open("cookies.pkl", "rb"))
for cookie in cookies:
    print cookie
    driver.add_cookie(cookie)

add_cookies are throwing this error:

selenium.common.exceptions.WebDriverException: Message: invalid cookie domain: invalid domain:".twitter.com" (Session info: chrome=55.0.2883.95) (Driver info: chromedriver=2.24.417412 (ac882d3ce7c0d99292439bf3405780058fcca0a6),platform=Mac OS X 10.12.1 x86_64)

I tried this already, SO PLEASE DONT LINK ME TO IT( Selenium addCookie getting Invalid Cookie Domain Exception even though I'm on the right domain )

Ive also tried changing chromedriver versions, changing my code a million times and banging my head against the wall. none of those worked.

Please help, thank you very much

Answer 1

I was getting this error too in Py selenium.

The solution is: First visit the home page of the website whose cookies you are trying to add.

    # first visit home page
    url = "https://www.website.com"
    driver.get(url)

    # add cookies from pickled-txt or a txt file
    cookies = pickle.load(open("cookies.pkl", "rb"))
    for cookie in cookies:
        driver.add_cookie(cookie)

    # visit again and you shall see your account logged in
    url = "https://www.website.com"
    driver.get(url)

The reason is:

1. Selenium webdriver init with default url data: .
2. add_cookie require current url is under the domain pattern of cookie.
3. data: will not match any cookie domain

So, you get invalid cookie domain error.

Answer 2

I was very much anxious with this error , Like other answers have suggested we first have to load the page then we have to load cookies and then again load the page and voila .

import pickle
from selenium import webdriver

def save_cookie(driver):
    with open("cookie", 'wb') as filehandler:
        pickle.dump(driver.get_cookies(), filehandler)
def load_cookie(driver):
     with open("cookie", 'rb') as cookiesfile:
         cookies = pickle.load(cookiesfile)
         for cookie in cookies:
             print(cookie)
             driver.add_cookie(cookie)

driver = webdriver.Chrome(ChromeDriverManager().install())
url = 'https://www.example.com'
driver.get(url)
load_cookie(driver)
# Do you task here 
save_cookie(driver)
driver.quit()
