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 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 https://www.iana.org/domains/root/db
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
域名信息查询网站 https://whois.aliyun.com/https://whois.cloud.tencent.com/https://who.is/https://www.whois.com/whois/https://whois.chinaz.com/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

-*- coding: utf-8 -*- import socket def 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 % IANA WHOIS server % for more information on IANA, visit http://www.iana.org % This query returned 1 object refer: whois.cnnic.cn domain: CN organisation: China Internet Network Information Center (CNNIC) address: No. 4, South 4th Street address: Zhong Guan Cun address: Beijing 100190 address: China contact: administrative name: Yu Zeng organisation: China Internet Network Information Center (CNNIC) address: No. 4, South 4th Street address: Zhong Guan Cun address: Beijing 100190 address: China phone: +8610-58813686 fax-no: +8610-58813632 e-mail: [email protected] contact: technical name: Yuedong Zhang organisation: China Internet Network Information Center (CNNIC) address: No. 4, South 4th Street address: Zhong Guan Cun address: Beijing 100190 address: China phone: +8610-58813202 fax-no: +8610-58812666 e-mail: [email protected] nserver: A.DNS.CN 2001:dc7:0:0:0:0:0:1 203.119.25.1 nserver: B.DNS.CN 203.119.26.1 nserver: C.DNS.CN 203.119.27.1 nserver: D.DNS.CN 2001:dc7:1000:0:0:0:0:1 203.119.28.1 nserver: E.DNS.CN 203.119.29.1 nserver: F.DNS.CN 195.219.8.90 nserver: G.DNS.CN 66.198.183.65 nserver: NS.CERNET.NET 202.112.0.44 ds-rdata: 57724 8 2 5d0423633eb24a499be78aa22d1c0c9ba36218ff49fd95a4cdf1a4ad97c67044 whois: whois.cnnic.cn status: ACTIVE remarks: Registration information: http://www.cnnic.cn/ created: 1990-11-28 changed: 2018-03-01 source: IANA注意到，这就是该域名信息所在服务器 refer: whois.cnnic.cn2、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www domain = '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: [email protected] 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 https://www.nirsoft.net/whois-servers.txt 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': ['[email protected]'] }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":[ "[email protected]" ] } 4.3、第三方库：python-whois经测试，不可用 https://github.com/richardpenman/whoishttps://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/whois21https://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 https://gitee.com/mouday/domain-adminhttps://github.com/mouday/domain-adminhttps://pypi.org/project/domain-adminhttps://hub.docker.com/r/mouday/domain-admin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
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 参考 Windows和Linux下Whois命令的安装和使用 |
