使用python检查SSL证书到期情况
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
