域名备案时间怎么查询

import requests

def query_domain_registration(domain):
    # 这里假设服务商提供了一个API接口来查询备案信息
    api_url = f"https://api.yourdomainregistrar.com/domain/{domain}/registration"
    headers = {
        "Authorization": "Bearer YOUR_API_KEY"
    }
    response = requests.get(api_url, headers=headers)
    if response.status_code == 200:
        data = response.json()
        registration_date = data.get("registration_date")
        return registration_date
    else:
        return "查询失败，请检查域名或API密钥"

# 示例调用
domain = "example.com"
registration_date = query_domain_registration(domain)
print(f"域名 {domain} 的备案时间是: {registration_date}")
