【问题描述】：

完整的错误代码：

Traceback (most recent call last):
  File "C:\path\to\my\python\code\server_ssl_testing.py", line 15, in <module>
    response = ssock.recv(1024).decode("utf-8")
  File "C:\Program Files\Python39\lib\ssl.py", line 1228, in recv
    return super().recv(buflen, flags)
OSError: [WinError 10057] A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied

我创建了 SSL Socket 服务器和客户端，但随后服务器尝试从客户端接收信息失败并打印此文本上方的错误。

服务器：

import socket
import ssl

context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
context.load_cert_chain('certs/server-cert.pem', 'certs/server.key')

with socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) as sock:
    sock.bind(('localhost', 2642))
    sock.listen(5)
    with context.wrap_socket(sock, server_side=True) as ssock:
        conn, addr = ssock.accept()
        response = ssock.recv(1024).decode("utf-8")
        print(response)

客户：

import socket
import ssl

hostname = 'localhost'
context = ssl.create_default_context()

sock = socket.create_connection((hostname, 2642))
ssock = context.wrap_socket(sock, server_hostname=hostname)
msg = "Hello World!"
ssock.send(msg.encode("utf-8"))

【参考方案1】：

在 server.py 中我应该写 conn.recv 而不是 ssock.recv。 如果将来有人想这样做应该会有所帮助=)
