python - 套接字使用随机端口，我需要一个

Question

这是问题所在，我想在某个端口的两个网络中的两台计算机之间创建连接，但是当我运行运行时，我收到这条消息，每次都会向我显示不同的端口:

Accepted a connection request from 192.168.1.2:**12345**
DATA

这是监听代码:

import socket
import logging 


serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

serverSocket.bind(("**server's Local ip**",6464))

serverSocket.listen(1)

while(True):
    
    (clientConnected, clientAddress) = serverSocket.accept()
    print("Accepted a connection request from %s:%s"%(clientAddress[0], clientAddress[1])) #[0], ...[1]
    dataFromClient = clientConnected.recv(1024)
    print(dataFromClient.decode())

    clientConnected.send("Hello User".encode())
    user = dataFromClient
    cip = clientAddress
    LOG_FILENAME = '/home/user/listenlog.txt'
    logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG)
    logging.debug(cip)
    logging.debug(user)
    logging.debug("--------------------------------------------------------")

这是客户端代码:

import socket

clientSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

clientSocket.connect(("**Server's IP**",6464))


data = 'Hello'


clientSocket.send(data.encode())

dataFromServer = clientSocket.recv(1024)

print(dataFromServer.decode())

我应该如何使使用端口静态？

Answer 1

如果您获得的连接是公开的并且在 nat 之后
通常是一个随机端口，因为它来自 isp 或 nat 设备，所以我认为这不是本地的
