不加密的sslcontext

您可以创建一个虚拟的sslcontext,它返回一个看起来像sslsocket的套接字。

from socket import socket

class NonSSLContext():
    def wrap_socket(self, sock, *_, **__):
        sock.__class__ = NonSSLSocket
        return sock

class NonSSLSocket(socket):
    __slots__ = ()

    def do_handshake(self):
        pass

    def unwrap(self):
        self.__class__ = socket
        return self

可以用作(例如)

from ssl import SSLContext

encrypted_context = SSLContext(...
non_encrypted_context = NonSSLContext(...
context = encrypted_context if encrypt else non_encrypted_context
socket = ...
ssl_socket = context.wrap_socket(sock, ...
...
ssl_sock.do_handshake()
...
