Python TCP socket on connect OSError: [Errno 102] Operation not supported on socket

Question

我正在尝试通过 TCP 连接到套接字。 我在同一主机/端口地址上创建了一个 UDP 和 TCP 套接字，并创建如下：

self.udp_socket = socket(AF_INET, SOCK_DGRAM)

self.udp_socket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
self.udp_socket.bind((gethostname(), self.port))

self.tcp_socket = socket(AF_INET, SOCK_STREAM)
self.tcp_socket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)

self.t_lock = threading.Condition()

# UDP THREAD
self.listen_udp_thread = threading.Thread(
    name="Listen UDP", target=self.listen_udp
)
self.listen_udp_thread.daemon = True
self.listen_udp_thread.start()

# TCP THREAD
self.listen_tcp_thread = threading.Thread(
    name="Listen TCP", target=self.listen_tcp
)
self.listen_tcp_thread.daemon = True
self.listen_tcp_thread.start()

我正在听这样的 TCP 插座：

def listen_tcp(self):

    """Start listening for TCP connections"""
    self.tcp_socket.bind((gethostname(), self.port))
    self.tcp_socket.listen()
    print("TCP socket is listening...")

    while True:
        # Listen for TCP data
        conn, addr = self.tcp_socket.accept()  # accept connections
        if conn:
            print(f"Connected to {addr}")

        while True:
            with self.t_lock:
                data = conn.recv(2048)
                if not data:
                    self.t_lock.notify()
                    break  # this will close the connection
                print("TCP:", data)
                conn.send(data)

        conn.close()  # closes once connection broken

然后我在同一个 TCP 套接字上发送数据，如下所示：

def send_tcp(self, message, node_id, addr=None):

    """Wrapper function to send message and print to stdout"""

    if node_id is not None:
        addr = (gethostname(), self._id_to_port(node_id))

    with self.t_lock:
        self.print_out(message, addr)

        try:
            self.tcp_socket.connect(addr)
        except ConnectionRefusedError:
            print(
                f"> {bcolors.FAIL}Connection to {addr[0]}:{addr[1]} refused!{bcolors.ENDC}"
            )
        else:
            while True:
                self.tcp_socket.send(message.encode())
                response = self.tcp_socket.recv(2048)
                self.print_in("TCP RESPONSE: " + response, addr)
                if not response:
                    break

            self.tcp_socket.close()

        self.t_lock.notify()

但是，当我通过 TCP（调用send_tcp() ）发送消息时，我收到错误： OSError: [Errno 102] Operation not supported on socket

UDP 监听器/发送器中也使用了相同的t_lock 。 我能够在“节点”之间接收/发送 UDP ping（在我的情况下称为 class）很好。

任何帮助表示赞赏！
