Question

我正在尝试使用socketserver在Python 3.6.7中编写一个TCP服务器，该服务器侦听同一IP地址上的两个端口。这是我到目前为止想出的：

import socketserver

class TCPServer(socketserver.StreamRequestHandler):
    def handle(self):
        self.data = self.rfile.readline().strip()
        print(str(self.data))

if __name__ == "__main__":
    HOST = "localhost"
    DATA_PORT = 64000
    CONTROL_PORT = 64001
    data_server = socketserver.TCPServer((HOST, DATA_PORT), TCPServer)
    control_server = socketserver.TCPServer((HOST, CONTROL_PORT), TCPServer)

    try:
        while True:
            data_server.handle_request()
            control_server.handle_request()
    except KeyboardInterrupt:
        data_server.server_close()
        control_server.server_close()

然后我尝试使用以下客户端与服务器对话：

import socket
from time import sleep

HOST = "localhost"
DATA_PORT = 64000
CONTROL_PORT = 64001
data = "test data"

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as sock_d, socket.socket(
    socket.AF_INET, socket.SOCK_STREAM
) as sock_c:
    sock_d.connect((HOST, DATA_PORT))
    sock_c.connect((HOST, CONTROL_PORT))
    for cnt in range(5):
        sock_d.sendall(bytes(data + " " + str(cnt) + "\n", "utf-8"))
        print("Sent:     {}".format(cnt))
        sock_c.sendall(bytes(data + " " + str(cnt + 1) + "\n", "utf-8"))
        print("Sent:     {}".format(cnt + 1))
        sleep(1)

发生的是，在客户端，我得到以下输出：

Sent:     0
Sent:     1
Sent:     1
Sent:     2
Traceback (most recent call last):
  File "<...> client_test.py", line 15, in <module>
    sock_d.sendall(bytes(data + " " + str(cnt) + "\n", "utf-8"))
ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine

在服务器上时，我只会得到：

b'test data 0'
b'test data 1'

有人可以帮我指出我在这里想念的东西吗？
