Selenium如何使用safari Cookies

Question

我尝试使用Selenium并遇到Cookie问题，它在方法FindCookie中返回cookie等于null，Google Chrome和FireFox都运行良好

  public void SetCookie(string cookieName, string cookieValue)
    {

        var cookie = new Cookie(cookieName, cookieValue);
        driver.Manage().Cookies.AddCookie(cookie);
       // driver.Manage().Cookies.AddCookie(new Cookie(cookieName, cookieValue, "/"));

    }

    public string FindCookie(string cookieName)
    {
        var cookieNamed = driver.Manage().Cookies.GetCookieNamed(cookieName);
        if (cookieNamed == null)
            return null;
        return cookieNamed.Value;
    }

我如何为Safari工作？
