1、Whois前置知识
whois就是一个用来查询域名是否已经被注册,以及注册域名的详细信息的数据库
(如域名所有人、域名注册商)。
不同域名后缀的whois信息需要到不同的whois数据库查询
mportant;">参考:百度百科-whois域名查询协议
实现原理
根据域名从根服务器获取域名所在whois服务器
再根据域名从域名所在whois服务器获取域名信息
domain + rootServer => targetServer domain + targetServer => domainInfo
当然,如果知道了域名信息所在服务器,可以跳过第一步,直接查询域名信息
2、通过网页查询
2.1、方式一:通过原始网页查询
第一步:根据域名从根服务器获取域名所在whois服务器
根服务器网站:https://www.iana.org/whois
或者直接根据域名后缀在数据库中查找对应的whois服务器地址
第二步:再根据域名从域名所在whois服务器获取域名信息
注意看到返回信息中的refer
行
refer: whois.cnnic.cn
打开这个网站: https://whois.cnnic.cn,继续查询,
需要注意,这里查询的是一级域名,不能携带www,只能查询xiaomi.cn
2.2、方式二:第三方网站查询
域名信息查询网站
这些网站可以直接查询域名信息,他们后台做了优化不用再去逐级查询,可以看到,信息返回的并不是很完整
3、命令行whois查询
3.1、Windows环境命令行whois查询
官网:
下载链接: https://www.nirsoft.net/utils/whoiscl.zip
3.2、Linux 环境命令行whois查询
安装
yum install -y whois
查询示例
# 查看使用帮助$ whois --help# 查询域名信息$ whois xiaomi.cn Domain Name: xiaomi.cn ROID: 20070518s10001s40338355-cn Domain Status: clientTransferProhibited Registrant: 小米科技有限责任公司 Registrant Contact Email: dns-admin@xiaomi.com Sponsoring Registrar: 厦门易名科技股份有限公司 Name Server: ns3.dnsv5.com Name Server: ns4.dnsv5.com Registration Time: 2007-05-18 10:15:59 Expiration Time: 2024-06-18 10:15:59 DNSSEC: unsigned
需要注意,如果是二级域名就查询不到信息
$ whois www.xiaomi.cn Invalid parameter:www.xiaomi.cn
4、Python代码方式实现
4.1、通过Socket实现whois查询
使用环境
$ python --version Python 3.7.0
核心代码
# -*- coding: utf-8 -*-import socketdef whois_request(domain: str, server: str, port=43, timeout=5) -> str: """ 发送http请求,获取信息 :param domain: :param server: :param port: :return: """ # 创建连接 sock = socket.create_connection((server, port)) sock.settimeout(timeout) # 发送请求 sock.send(("%s\r\n" % domain).encode("utf-8")) # 接收数据 buff = bytes() while True: data = sock.recv(1024) if len(data) == 0: break buff += data # 关闭链接 sock.close() return buff.decode("utf-8")
1、第一步,根据域名从根服务器获取域名所在whois服务器
# 根服务器地址root_server = 'whois.iana.org'# 需要查询的域名domain = 'xiaoxi.cn'# 查询域名信息res = whois_request(domain, root_server)print(res)
返回数据

注意到,这就是该域名信息所在服务器
refer: whois.cnnic.cn
2、第二步:再根据域名从域名所在whois服务器获取域名信息
# whois服务器地址whois_server = 'whois.cnnic.cn'# 需要查询的域名,注意不能带wwwdomain = 'xiaoxi.cn'# 查询域名信息res = whois_request(domain, whois_server)print(res)
返回的信息
Domain Name: xiaomi.cn ROID: 20070518s10001s40338355-cn Domain Status: clientTransferProhibited Registrant: 小米科技有限责任公司 Registrant Contact Email: dns-admin@xiaomi.com Sponsoring Registrar: 厦门易名科技股份有限公司 Name Server: ns3.dnsv5.com Name Server: ns4.dnsv5.com Registration Time: 2007-05-18 10:15:59 Expiration Time: 2024-06-18 10:15:59 DNSSEC: unsigned
可以看到,我们查询到了和网站查询一样的信息
可以直接使用第三方整理的whois数据库对应地址
4.2、第三方库:whois
操作系统命令行工具 whois
的Python封装,依赖操作系统,不推荐
https://github.com/DannyCork/python-whois/
https://pypi.org/project/whois/
安装
$ pip install whois
示例
import whois domain = whois.query('www.baidu.com')print(domain.__dict__)
输出
{ 'name': 'baidu.com', 'tld': 'com', 'registrar': 'MarkMonitor Inc.', 'registrant_country': 'CN', 'creation_date': datetime.datetime(1999, 10, 11, 11, 5, 17), 'expiration_date': datetime.datetime(2026, 10, 11, 11, 5, 17), 'last_updated': datetime.datetime(2022, 9, 1, 3, 54, 43), 'status': 'clientDeleteProhibited https://icann.org/epp#clientDeleteProhibited', 'statuses': ['clientDeleteProhibited (https://www.icann.org/epp#clientDeleteProhibited)', 'clientDeleteProhibited https://icann.org/epp#clientDeleteProhibited', 'clientTransferProhibited (https://www.icann.org/epp#clientTransferProhibited)', 'clientTransferProhibited https://icann.org/epp#clientTransferProhibited', 'clientUpdateProhibited (https://www.icann.org/epp#clientUpdateProhibited)', 'clientUpdateProhibited https://icann.org/epp#clientUpdateProhibited', 'serverDeleteProhibited (https://www.icann.org/epp#serverDeleteProhibited)', 'serverDeleteProhibited https://icann.org/epp#serverDeleteProhibited', 'serverTransferProhibited (https://www.icann.org/epp#serverTransferProhibited)', 'serverTransferProhibited https://icann.org/epp#serverTransferProhibited', 'serverUpdateProhibited (https://www.icann.org/epp#serverUpdateProhibited)', 'serverUpdateProhibited https://icann.org/epp#serverUpdateProhibited'], 'dnssec': False, 'name_servers': ['ns1.baidu.com', 'ns2.baidu.com', 'ns3.baidu.com', 'ns4.baidu.com', 'ns7.baidu.com'], 'registrant': 'Beijing Baidu Netcom Science Technology Co., Ltd.', 'emails': ['abusecomplaints@markmonitor.com']}
json序列化之后得到域名信息
{ "name":"baidu.com", "tld":"com", "registrar":"MarkMonitor Inc.", "registrant_country":"CN", "creation_date":"1999-10-11 11:05:17", "expiration_date":"2026-10-11 11:05:17", "last_updated":"2022-09-01 03:54:43", "status":"clientDeleteProhibited https://icann.org/epp#clientDeleteProhibited", "statuses":[ "clientDeleteProhibited (https://www.icann.org/epp#clientDeleteProhibited)", "clientDeleteProhibited https://icann.org/epp#clientDeleteProhibited", "clientTransferProhibited (https://www.icann.org/epp#clientTransferProhibited)", "clientTransferProhibited https://icann.org/epp#clientTransferProhibited", "clientUpdateProhibited (https://www.icann.org/epp#clientUpdateProhibited)", "clientUpdateProhibited https://icann.org/epp#clientUpdateProhibited", "serverDeleteProhibited (https://www.icann.org/epp#serverDeleteProhibited)", "serverDeleteProhibited https://icann.org/epp#serverDeleteProhibited", "serverTransferProhibited (https://www.icann.org/epp#serverTransferProhibited)", "serverTransferProhibited https://icann.org/epp#serverTransferProhibited", "serverUpdateProhibited (https://www.icann.org/epp#serverUpdateProhibited)", "serverUpdateProhibited https://icann.org/epp#serverUpdateProhibited" ], "dnssec":false, "name_servers":[ "ns1.baidu.com", "ns2.baidu.com", "ns3.baidu.com", "ns4.baidu.com", "ns7.baidu.com" ], "registrant":"Beijing Baidu Netcom Science Technology Co., Ltd.", "emails":[ "abusecomplaints@markmonitor.com" ]}
4.3、第三方库:python-whois
经测试,不可用
https://github.com/richardpenman/whois
https://pypi.org/project/python-whois/
$ pip install python-whois
示例
import whois w = whois.whois('example.com')w.expiration_date# datetime.datetime(2022, 8, 13, 4, 0)
4.4、第三方库:whois21
经测试,可用
https://github.com/MPCodeWriter21/whois21
https://pypi.org/project/whois21/
pip install whois21
示例
import whois21 query = 'github.com'whois = whois21.WHOIS(query)print(f'Creation date : {whois.creation_date}')print(f'Expiration date : {whois.expires_date}')print(f'Updated date : {whois.updated_date}')
5、使用Domain Admin
基于Python + Vue3.js 技术栈实现的域名和SSL证书监测平台
文档
安装
pip install domain-admin
启动运行
$ gunicorn 'domain_admin.main:app'
访问地址:http://127.0.0.1:8000
默认的管理员账号
账号:admin
密码:123456
6、中文域名
通过接口直接查询中文域名,会提示没有查询结果。这时候需要将中文域名进行编码
比如:小米.中国 会解析为 xn–yets76e.xn–fiqs8s/
在线编码:http://tools.jb51.net/punycode/index.php
其实,中文后缀的域名可以不编码,主要是中英结合的域名, 比如 http://中万.cn/
从浏览器直接复制过来是http://xn–chq7c.cn/
这是一种叫做:Punycode的编码方式
print("中万".encode('punycode').decode())# chq7c
然后加上前缀xn--
,就和上面的结果一致了
xn--chq7c
