用python写登录https://account.aliyun.com/login/login.htm后跳转到一个页面下载文件

以下是用Python3编写的示例代码，可供参考：

import requests
from bs4 import BeautifulSoup

# 登录阿里云账户
session = requests.Session()
login_url = "https://account.aliyun.com/login/login.htm"
login_data = {
    "resource_url": "https://workorder.console.aliyun.com/console.htm",
    "password": "YourPassword",
    "username": "YourUserName",
    "appEntrance": "account_portal"
}
session.post(login_url, data=login_data)

# 获取需要下载的文件链接
file_url = "https://example.alicdn.com/example_file.zip"
response = session.get(file_url)

# 下载文件并保存到本地
with open("example_file.zip", "wb") as file:
    file.write(response.content)

注：在使用该代码前，需要先安装requests和beautifulsoup4库。其中，requests库用于发送HTTP请求，而beautifulsoup4库用于解析HTML文档。您也可以用其他方式进行相关操作。
