设置带有签名证书的ssl服务器套接字

openssl genrsa -out server.key 2048
openssl req -new -key server.key -out server.csr

import ssl
from socket import socket

context = ssl.SSLContext(ssl.PROTOCOL_TLS)
context.load_cert_chain('server.crt', 'server.key')

server = socket()
server.bind(('localhost', 443))
server.listen(5)

conn, addr = server.accept()
ssl_conn = context.wrap_socket(conn, server_side=True)

while True:
    data = ssl_conn.recv(1024)
    if not data:
        break
    ssl_conn.sendall(data)

ssl_conn.shutdown(ssl.SHUT_RDWR)
ssl_conn.close()
server.close()
