如何通过python登录stackoverflow.com？

pip install requests
pip install beautifulsoup4

import requests
from bs4 import BeautifulSoup

# 登录信息
username = 'your_username'
password = 'your_password'

# 获取登录页面
login_url = 'https://stackoverflow.com/users/login'
response = requests.get(login_url)

# 解析登录页面
soup = BeautifulSoup(response.text, 'html.parser')
fkey = soup.find('input', {'name': 'fkey'})['value']

# 登录
payload = {
    'email': username,
    'password': password,
    'fkey': fkey,
    'oauth_version': '',
    'oauth_server': ''
}

response = requests.post('https://stackoverflow.com/users/login/submit', data=payload)

# 检查登录是否成功
if response.url == 'https://stackoverflow.com/':
    print('登录成功！')
else:
    print('登录失败，请检查您的用户名和密码。')
