Changing ROBLOSECURITY Cookie in Selenium

Question

I am attempting to change the cookie of .ROBLOSECURITY on www.roblox.com. This is for an attempted robot that will cycle through accounts.

I get the error:

"selenium.common.exceptions.UnableToSetCookieException: Message: unable to set cookie
(Session info: chrome=86.0.4240.75)"

This is the code so far...

with open("CookieList.txt") as CookieFile:
    Cookies = CookieFile.readlines()
    for Cookie in Cookies:
        PATH = "C:\Program Files (x86)\chromedriver.exe"
        driver = webdriver.Chrome(PATH)
        driver.get("https://www.roblox.com/games/" + GameID + "/Name/")
        #input("Log into your account in the new browser. Type 'Done' when finished.\n")
        roblocookie = {
            'name': "ROBLOSECURITY",
            'value': Cookie,
        }
        driver.add_cookie(roblocookie)

I've tried making "ROBLOSECURITY", ".ROBLOSECURITY" and changing the domains to what it is on the website, but to no avail.

Answer 1

To use any of the cookie handling methods in WebDriver, we first need to import the Cookie class. To do that, we use:

import org.openqa.selenium.Cookie;

Retrieve all cookies

// This method gets all the cookies
public Set<Cookie> getAllCookies() {
    return driver.manage().getCookies();
}

Retrieve a named cookie

// This method gets a specified cookie
public Cookie getCookieNamed(String name) {
    return driver.manage().getCookieNamed(name);
}

Retrieve the value of a cookie

// This method gets the value of a specified cookie
public String getValueOfCookieNamed(String name) {
    return driver.manage().getCookieNamed(name).getValue();
}

Add a cookie

// This method adds or creates a cookie
public void addCookie(String name, String value, String domain, String path, Date expiry) {
    driver.manage().addCookie(
    new Cookie(name, value, domain, path, expiry));
}

Add a set of cookies

// This method adds set of cookies for a domain
public void addCookiesToBrowser(Set<Cookie> cookies, String domain) {
    for (Cookie c : cookies) {
        if (c != null) {
            if (c.getDomain().contains(domain)){
                driver.manage().addCookie(
                new Cookie(name, value, domain, path, expiry));
            }
        }
    }
    driver.navigate().refresh();
}
