python脚本--检查域名证书到期时间
需要的依赖:
pip install python-dateutil pip install pytz
python脚本内容:
#!/usr/bin/env python3 import ssl, socket import requests from dateutil import parser import pytz requests.packages.urllib3.disable_warnings() try: _create_unverified_https_context = ssl._create_unverified_context except AttributeError: # Legacy Python that doesn't verify HTTPS certificates by default pass else: # Handle target environment that doesn't support HTTPS verification ssl._create_default_https_context = _create_unverified_https_context def get_domain_content(domain): requests.packages.urllib3.disable_warnings() url = 'https://' + domain response = requests.get(url, verify=False).headers print(response) def get_my_domain(mydomain): try: socket.setdefaulttimeout(5) my_addr = socket.getaddrinfo(mydomain, None) c = ssl.create_default_context() s = c.wrap_socket(socket.socket(), server_hostname=mydomain) s.connect((mydomain, 443)) my_cert = s.getpeercert() get_my_cert_dated(mydomain, my_cert, my_addr) except ssl.CertificateError and socket.gaierror as e: pass def get_my_cert_dated(domain, certs, my_addr): cert_beginning_time = parser.parse(certs['notBefore']).astimezone(pytz.utc) cert_end_time = parser.parse(certs['notAfter']).astimezone(pytz.utc) print('域名:(%s) 证书失效时间: %s' % (domain, cert_end_time)) def read_domain_files(): with open('./domain.txt', 'r', encoding="utf-8") as file: for domain in file: try: get_my_domain(domain.strip()) except Exception as e: print('域名: (%s)-%s' %(domain.strip(), e)) if __name__ == "__main__": read_domain_files()
域名存放到和python脚本相同目录,名称为:domain.txt
