如何自动更新动态域名

import requests
import time

# 配置No-IP的用户名和密码
username = "your_username"
password = "your_password"
hostname = "your_hostname.no-ip.biz"

def update_ip():
    try:
        # 获取当前公网IP
        response = requests.get("https://api.ipify.org")
        current_ip = response.text

        # 更新No-IP的DNS记录
        url = f"https://{username}:{password}@dynupdate.no-ip.com/nic/update?hostname={hostname}&myip={current_ip}"
        response = requests.get(url)

        if response.text.startswith("good") or response.text.startswith("nochg"):
            print(f"IP updated successfully: {current_ip}")
        else:
            print(f"Failed to update IP: {response.text}")
    except Exception as e:
        print(f"Error updating IP: {e}")

if __name__ == "__main__":
    while True:
        update_ip()
        time.sleep(60 * 10)  # 每10分钟检查一次IP地址
