python套接字服务器与真正的IP地址

Question

我正在玩我的python服务器，但我使用localhost，我想通过互联网。我的代码到目前为止是：

import socket
import threading
import socketserver

class ThreadedTCPRequestHandler(socketserver.BaseRequestHandler):

    def handle(self):
        data = self.request.recv(1024)
        cur_thread = threading.current_thread()
        response = "{}: {}".format(cur_thread.name, data)
        self.request.sendall(b'worked') 

class ThreadedTCPServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
    pass

def client(ip, port, message):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.connect((ip, port))
    try:
        sock.sendall(message)
        response = sock.recv(1024)
        print("Received: {}".format(response))
    finally:
        sock.close()

if __name__ == "__main__":
    # Port 0 means to select an arbitrary unused port
    HOST, PORT = "0.0.0.0", 9001

    server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
    ip, port = server.server_address

    # Start a thread with the server -- that thread will then start one
    # more thread for each request
    server_thread = threading.Thread(target=server.serve_forever)
    # Exit the server thread when the main thread terminates
    server_thread.daemon = True
    server_thread.start()
    print("Server loop running in thread:", server_thread.name)
    ip = '12.34.56.789' #Not my real ip address This is just to hide my ip
    print(ip, PORT)

    client(ip, PORT, b'Hello World 1')
    #client(ip, port, b'Hello World 2')
    #client(ip, port, b'Hello World 3')

    server.shutdown()

当我运行这个我得到错误：

Server loop running in thread: Thread-1
12.34.56.789 9001
Traceback (most recent call last):
  File "C:/Python32/serverTesty.py", line 43, in <module>
    client(ip, PORT, b'Hello World 1')
  File "C:/Python32/serverTesty.py", line 18, in client
    sock.connect((ip, port))
socket.error: [Errno 10061] No connection could be made because the target machine actively refused it

我知道端口是可行的，因为当我的程序运行时，当我在端口9001上使用canyouseeme.org时，它表示它的活动和工作。所以我想我的连接错了。
