首先，您需要使用您的用户名/电子邮件和密码登录，就像您在上面的脚本中所做的那样。
接下来，您应该保存cookie，以便下次继续，您只需加载这些cookie即可直接打开已登录的网站。

json_object = json.dumps(driver.get_cookies())
# save the cookies in a file 
with open("cookies.json", "w") as outfile:
    outfile.write(json_object)

下一次，你只需要直接去网站，加载cookie并刷新它。

# open then website
driver.get("https://www.redbubble.com/")

f = open('cookies.json')
cookies = json.loads(f)
# Load cookies to the driver
for cookie in cookies:
    driver.add_cookie(cookie)

time.sleep(2)

# refresh the browser
driver.refresh()

谢谢你的解决方案，现在这里的问题是当点击上传URL时检测到cloudflare;我不知道我已经使用了循环的概念来摆脱cloudflare，但它没有检测到cloudflare按钮。
