python检查SSL证书 基于python检查SSL证书到期情况代码实例
zack_赵康 人气:0结合邮件告警和页面展示,再多的域名证书到期情况即可立马知道
代码示例:
# coding: utf-8 # 查询域名证书到期情况 import re import time import subprocess from datetime import datetime from io import StringIO def main(domain): f = StringIO() comm = f"curl -Ivs https://{domain} --connect-timeout 10" result = subprocess.getstatusoutput(comm) f.write(result[1]) m = re.search('start date: (.*?)\n.*?expire date: (.*?)\n.*?common name: (.*?)\n.*?issuer: CN=(.*?)\n', f.getvalue(), re.S) start_date = m.group(1) expire_date = m.group(2) common_name = m.group(3) issuer = m.group(4) # time 字符串转时间数组 start_date = time.strptime(start_date, "%b %d %H:%M:%S %Y GMT") start_date_st = time.strftime("%Y-%m-%d %H:%M:%S", start_date) # datetime 字符串转时间数组 expire_date = datetime.strptime(expire_date, "%b %d %H:%M:%S %Y GMT") expire_date_st = datetime.strftime(expire_date,"%Y-%m-%d %H:%M:%S") # 剩余天数 remaining = (expire_date-datetime.now()).days print ('域名:', domain) print ('通用名:', common_name) print ('开始时间:', start_date_st) print ('到期时间:', expire_date_st) print (f'剩余时间: {remaining}天') print ('颁发机构:', issuer) print ('*'*30) time.sleep(0.5) if __name__ == "__main__": domains = ['www.baidu.com'] for domain in domains: main(domain)
结果示例:
域名: www.baidu.com
通用名: baidu.com
开始时间: 2019-05-09 01:22:02
到期时间: 2020-06-25 05:31:02
剩余时间: 82天
颁发机构: GlobalSign Organization Validation CA - SHA256 - G2,O=GlobalSign nv-sa,C=BE
