可以使用 Python 批量获取多个 URL 的国密证书信息。可以在之前获取单个 URL 国密证书信息的代码基础上进行修改，将多个 URL 存储在一个列表中，然后遍历该列表，依次获取每个 URL 的国密证书信息。 以下是示例代码： ```python import ssl import socket from gmssl import x509 def get_certificate(hostname, port=443): context = ssl.create_default_context() try: with socket.create_connection((hostname, port)) as sock: with context.wrap_socket(sock, server_hostname=hostname) as ssock: der_cert = ssock.getpeercert(True) return ssl.DER_cert_to_PEM_cert(der_cert) except Exception as e: print(f"获取 {hostname} 证书时出错: {e}") return None def parse_gm_cert(cert_pem): if cert_pem is None: return try: cert = x509.Certificate() cert.parse_pem(cert_pem.encode()) print("证书版本:", cert.get_version()) print("序列号:", cert.get_serial_number().hex()) print("颁发者:", cert.get_issuer()) print("使用者:", cert.get_subject()) print("有效期从:", cert.get_not_before()) print("有效期至:", cert.get_not_after()) print("公钥算法:", cert.get_pubkey_algorithm()) print("签名算法:", cert.get_signature_algorithm()) extensions = cert.get_extensions() for ext in extensions: print(f"扩展 {ext.get_oid()}: {ext.get_value()}") print("-" * 50) except Exception as e: print(f"解析证书时出错: {e}") urls = [ "https://example1.com", "https://example2.com" # 可以添加更多的 URL ] for url in urls: if "https://" in url: hostname = url.split("https://")[1].split("/")[0] else: hostname = url.split("/")[0] cert_pem = get_certificate(hostname) parse_gm_cert(cert_pem) ```
