When web scraping, we often need to save the connection state like browser cookies and resume it later. Using Selenium, to save and load cookies we can use driver.get_cookies() and driver.add_cookie() methods:
import json
from pathlib import Path
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://www.google.com")
# Get cookies to a json file:
Path('cookies.json').write_text(
json.dumps(driver.get_cookies(), indent=2)
)
# retrieve cookies from a json file
for cookie in json.loads(Path('cookies.json').read_text()):
driver.add_cookie(cookie)
driver.quit()
