I would like to learn how to save and load a session (cookies) with nodriver. I found an example (https://stabler.tech/blog/nodriver-a-new-webscraping-tool), but the code seems to be outdated.

I found some old github incidents, where the developer said something about it and posted some code. (https://github.com/ultrafunkamsterdam/undetected-chromedriver/issues/1817 // https://github.com/ultrafunkamsterdam/undetected-chromedriver/issues/1816)

I tried different stuff for hours, even with using Gemini and ChatGPT, but I cant do it. Iam pretty new to Python. Could someone help me?

Here is executable example code:

import asyncio
import nodriver as uc

user = "User"
password = "passwort"


async def type_text(element, text):
    for char in text:
        await element.send_keys(char)


async def main():
    browser = None
    try:
        browser = await uc.start()
        page = await browser.get('https://html-php.de/php/zb_php_f/index.php')

        email_field = await page.select("input[name=a_nick]")
        password_field = await page.select("input[name=a_pass]")
        login_task = None

        if email_field and password_field:
            await type_text(email_field, user)
            await type_text(password_field, password)

            login_button = await page.select("input[type=submit]")
            if login_button:
                login_task = asyncio.create_task(login_button.click())

        if login_task:
            await login_task

    except Exception as e:
        print(f"Error during login: {e}")
    finally:
        if browser:
            # Wait for 10 seconds before closing
            await asyncio.sleep(10)
            await browser.stop()


if __name__ == '__main__':
    uc.loop().run_until_complete(main())

I want to achieve, that the second time I start it, its already logged in. (so the exception should get thrown).

Thanks for any help! 🙂

(I couldnt use a “nodriver” tag, so I used “undetected-chromedriver”, its the predecessor)
