import re

from datetime import datetime
from io import StringIO
def main(domain):

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)

# time 字符串转时间数组
start_date = time.strptime(start_date, "%b %d %H:%M:%S %Y GMT")

# datetime 字符串转时间数组

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 ******************************
