安装 openssl 依赖

sudo pip3 install -i https://mirrors.aliyun.com/pypi/simple/ pyOpenSSL

执行

python3 site.py

site.py

import ssl
import OpenSSL
import datetime

def get_cert_expiration(hostname):

    # sni 站点
    port = 443
    conn = ssl.create_connection((hostname, port))
    context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
    sock = context.wrap_socket(conn, server_hostname=hostname)
    cert = ssl.DER_cert_to_PEM_cert(sock.getpeercert(True))
    x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
    expiration = datetime.datetime.strptime(
        x509.get_notAfter().decode("utf-8"), "%Y%m%d%H%M%SZ")

    return str(expiration)

sites = [
    "www.yidiankuaile.com",
