域名到期不续费后果

import whois
import datetime

def check_domain_expiration(domain):
    w = whois.whois(domain)
    expiration_date = w.expiration_date
    if isinstance(expiration_date, list):
        expiration_date = expiration_date[0]
    
    today = datetime.datetime.now()
    days_until_expiration = (expiration_date - today).days
    
    if days_until_expiration <= 30:
        print(f"域名 {domain} 即将到期，还有 {days_until_expiration} 天，请及时续费！")
    else:
        print(f"域名 {domain} 还有 {days_until_expiration} 天到期，目前无需续费。")

# 示例使用
check_domain_expiration("example.com")
