Eliminate entering QR - Whatsapp web automated by selenium - Java

Question

I'm trying to eliminate the process of the QR code after the first I'm doing it.

My code to run Whatsapp trough a web driver:

public class DriverTester {

public static void main(String[] args) {

    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    capabilities.setCapability(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, UnexpectedAlertBehaviour.IGNORE);
    ChromeDriverService service = new ChromeDriverService.Builder()
            .usingDriverExecutable(new File("C:\\whatsup\\src\\main\\resources\\chromedriver.exe"))
            .usingAnyFreePort()
            .build();

    ChromeOptions options = new ChromeOptions();
    options.merge(capabilities);
    ChromeDriver driver = new ChromeDriver(service, options);

    driver.navigate().to("https://web.whatsapp.com/");

    while (driver.findElements(By.xpath(XPaths.autoStartReady)).size() == 0);

    LocalStorage localStorage = driver.getLocalStorage();

    driver.close();

    driver = new ChromeDriver(service, options);

    for (String key : localStorage.keySet()){
        String value = localStorage.getItem(key);
        driver.executeScript("window.localStorage.setItem('"+key+"', '"+value+"');");
    }

    driver.navigate().to("https://web.whatsapp.com/");

}

}

When the web browser opens for the first time, I'm doing the QR code routine on my phone. The exception was raised while executing the javascript code.

But I'm getting the next exception:

Exception in thread "main" org.openqa.selenium.NoSuchSessionException: no such session

If I'm trying to save the cookies, the cookies set is empty (cannot save any cookie, still don't know why).

How can I skip this process of the QR after the first time? If someone knows how to skip it without even doing it once, it will be also helpful (but I think too much difficult for now).

Thanks in advance!

Use profiles!

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument(r"user-data-dir=D:\Python\Memory\WebWhatsAppBot")

navegador = webdriver.Chrome(
executable_path="D:\Python\WebWhatsAppBot\chromedriver.exe", chrome_options=options)
navegador.get("https://web.whatsapp.com/")

Can you explain your solution? – Roni Koren Kurtberg Aug 10 '18 at 06:10
Yep, profile is the right way to bypass QR code scanning each time. You just need to scan ones. I have also used profile – Shyam Sep 17 '19 at 02:32

Marcelo's answer is correct but poorly explained in my opinion, so here's what worked for me:

Create a folder in your project directory to store all the cache that the chromedriver session will create (it's also nice to ignore the content in your .gitignore file).

And then, start the webdriver options and set the directory.

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
import time

options = webdriver.ChromeOptions()
options.add_argument(r"user-data-dir=./driver/data")
driver = webdriver.Chrome(executable_path=r'./driver/chromedrive84_win', options=options)
driver.get('https://web.whatsapp.com/')

You can skip the qr code scaning after first attemp if you have not use

ChromeOptions options = new ChromeOptions();
options.addArguments("--incognito"); 
options.addArguments("--no-sandbox");

after removing --incognito type option
