如何在登录后使用Python抓取不断更新的JavaScript？

import requests
from bs4 import BeautifulSoup
from selenium import webdriver

# 登录网站，获取cookie
login_url = 'https://example.com/login'
data = {'username': 'your_username', 'password': 'your_password'}
response = requests.post(login_url, data=data)
cookie = response.cookies

# 访问包含JavaScript数据的页面
data_url = 'https://example.com/data'
response = requests.get(data_url, cookies=cookie)
html = response.text

# 解析JavaScript数据
soup = BeautifulSoup(html, 'html.parser')
javascript_data = soup.find('script', {'type': 'text/javascript'}).string

# 使用Selenium执行JavaScript代码
driver = webdriver.Chrome()  # 需要安装Chrome浏览器和对应的驱动
driver.get(data_url)
updated_data = driver.execute_script(javascript_data)

# 处理数据
# ...

# 关闭浏览器
driver.quit()
