怎么查域名是否快过期

import whois
from datetime import datetime, timedelta

def check_domain_expiration(domain):
    try:
        w = whois.whois(domain)
        expiration_date = w.expiration_date
        if isinstance(expiration_date, list):
            expiration_date = expiration_date[0]
        days_until_expiration = (expiration_date - datetime.now()).days
        if days_until_expiration < 30:  # 提前30天提醒
            print(f"域名 {domain} 即将过期，剩余天数: {days_until_expiration}")
        else:
            print(f"域名 {domain} 还有较长时间才过期，剩余天数: {days_until_expiration}")
    except Exception as e:
        print(f"查询域名 {domain} 时出错: {e}")

# 示例调用
check_domain_expiration("example.com")
