域名要到期了怎么抢注

import whois
import datetime
import time

def check_domain_expiration(domain):
    w = whois.whois(domain)
    expiration_date = w.expiration_date
    if isinstance(expiration_date, list):
        expiration_date = expiration_date[0]
    return expiration_date

def monitor_and_register(domain, registrar_api_key):
    while True:
        expiration_date = check_domain_expiration(domain)
        current_time = datetime.datetime.now()
        time_to_expiration = expiration_date - current_time
        if time_to_expiration.days <= 7:  # 提前7天开始监控
            print(f"Domain {domain} is about to expire in {time_to_expiration.days} days.")
            # 调用注册商API进行抢注
            register_domain(domain, registrar_api_key)
            break
        time.sleep(86400)  # 每天检查一次

def register_domain(domain, api_key):
    # 调用注册商API进行域名注册
    # 这里需要根据具体的注册商API文档进行实现
    print(f"Registering domain {domain} using API key {api_key}")

# 示例调用
monitor_and_register("example.com", "your_registrar_api_key")
