How can I get cookie request headers for webscraping - python

I am trying to scrape a that is blocking the scraper based on cookies. When I go incognito, open devtools and select the request header cookies from the network tab, the scraping works until the cookies gett blocked. Using undetected chromedriver I can't access the site from python, which is why I am having to manually input the cookies. I've tried all the recommended options for additional settings and headers to try and get undetected chromedrive to work, but it will not.

How to automatically accept cookie for a website with selenium python

I am using selenium to automate some test on many websites. Everytime I get the cookie wall popup.
I know I can search for the xpath of the Accept cookie button and then click on it with selenium. This solution is not convenient for me because I need to search for the button manually. I want a script that accepts cookie for all sites automatically.
What I tried to do is get a cookie jar by making a request to the website with python requests and then set the cookie in Selenium ==> Not working with many error
I found this on stackoverflow :
fp = webdriver.FirefoxProfile()
fp.set_preference("network.cookie.cookieBehavior", 2)
driver = webdriver.Firefox(firefox_profile=fp, executable_path="./geckodriver")
This worked for google.com (no accept cookie popup appeared) but it failed with facebook.com and instagram.com

How to navigate using selenium Webdriver without being logged out?

I have managed to log into a website using webdriver. Now that I am logged in, I would like to navigate to a new URL on the same site using driver.get(). However, often (not all the time) in doing so I am logged out of the website. I have tried to duplicate the cookies after navigating to the new url, however, I still get the same problem. I am unsure if this method should work / if I am doing it correctly.
cookies = driver.get_cookies()
driver.get(link)
timer(time_limit)
for i in cookies:
driver.add_cookie(i)
How can I navigate to a different part of the website (without clicking links on the screen) whilst maintaining my log-in session?
I just had to refresh the page after adding the cookies: driver.refresh()

Can't get cookies using selenium

I am using selenium python, I create a webdriver using firefox binary and profile (tor browser), I get a webpage, I navigate and when I try to use
cookies = driver.get_cookies()
It returns an empty list, but if I check the webpage using dev tools in the Storage -> Cookies they are set, but if I use the console typing
document.cookie
It returns an empty string.
Is it a problem about tor browser that dont allow to use this kind of js codes or am I missing something?

How can I use saved cookies with selenium?

I am trying to make a tool that does things on your website account. Some things use reCAPTCHA after you log in, so I want to know how I could use the firefox's saved cookies the are on the normal browser on selenium so that it skips the reCAPTCHA and assumes you're not a bot.

Browser Simulation and Scraping with windmill or selenium, how many http requests?

I want to use windmill or selenium to simulate a browser that visits a website, scrapes the content and after analyzing the content goes on with some action depending of the analysis.
As an example. The browser visits a website, where we can find, say 50 links. While the browser is still running, a python script for example can analyze the found links and decides on what link the browser should click.
My big question is with how many http Requests this can be done using windmill or selenium. I mean do these two programs can simulate visiting a website in a browser and scrape the content with just one http request, or would they use another internal request to the website for getting the links, while the browser is still running?
Thx alot!
Selenium uses the browser but number of HTTP request is not one. There will be multiple HTTP request to the server for JS, CSS and Images (if any) mentioned in the HTML document.
If you want to scrape the page with single HTTP request, you need to use scrapers which only gets what is present in the HTML source. If you are using Python, check out BeautifulSoup.
