IP 地址引发 Python 套接字错误

Question

我正在尝试连接位于不同位置的 2 台远程计算机。

每次我在参数中添加我的公共 IP 地址时，都会引发错误。 OSError: [WinError 10049] The requested address is not valid in its context

这是我在这个项目中使用的服务器端代码：

import socket
import threading

HEADER = 64
PORT = 5050
SERVER = **PUBLIC IP**
ADDR = (SERVER, PORT)
FORMAT = 'utf-8'
DISCONNECT_MESSAGE = "!DISCONNECT"
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(ADDR)


def handle_client(conn, addr):
  print(f"[NEW CONNECTION] {addr} connected.")

  connected = True
  while connected:
      msg_length = conn.recv(HEADER).decode(FORMAT)
      if msg_length:
          msg_length = int(msg_length)
          msg = conn.recv(msg_length).decode(FORMAT)
          if msg == DISCONNECT_MESSAGE:
              connected = False

          print(f"[{addr}] {msg}")
          conn.send("Msg received".encode(FORMAT))

  conn.close()


def start():
  server.listen()
  print(f"[LISTENING] Server is listening on {SERVER}")
  while True:
      conn, addr = server.accept()
      thread = threading.Thread(target=handle_client, args=(conn, addr))
      thread.start()
      print(f"[ACTIVE CONNECTIONS] {threading.activeCount() - 1}")


print("[STARTING] server is starting...")
start()

设置SERVER = '0.0.0.0'绑定到服务器的IP。
