python 双机通信

Python双机通信可以使用socket库来实现。在服务器端，可以使用TCP协议来实现局域网聊天。以下是一个示例代码：

from socket import *
from threading import Thread
import time

IP = '0.0.0.0'  # 全部开放
PORT = 50000
BUFLEN = 512

listenSocket = socket(AF_INET, SOCK_STREAM)
listenSocket.bind((IP, PORT))
listenSocket.listen(5)
print(f'success,waiting for {PORT}')

dataSocket, addr = listenSocket.accept()
print('connect one', addr)

class Get(Thread):
    def run(self):
        while True:
            time.sleep(1)
            recved = dataSocket.recv(BUFLEN)
            if not recved:
                break
            info = recved.decode()
            print(' << ' + info + '\n>>', end='')

class Send(Thread):
    def run(self):
        while True:
            info = input('>>')
            dataSocket.send(info.encode())

if __name__ == '__main__':
    Send().start()
    Get().start()

在客户端，可以使用相同的socket库来实现与服务器的通信。以下是一个示例代码：

import os
import sys
import time
from socket import *
from threading import Thread

IP = '略'  # 服务器ip
SERVER_PORT = 50000
BUFLEN = 512

print("he isn't here")

while True:
    try:
        time.sleep(5)
        dataSocket = socket(AF_INET, SOCK_STREAM)
        dataSocket.connect((IP, SERVER_PORT))
        break
    except:
        pass

class Send(Thread):
    def run(self):
        while True:
            toSend = input(">>")
            if toSend == '':
                break
            dataSocket.send(toSend.encode())

class Get(Thread):
    def run(self):
        while True:
            time.sleep(1)
            recved = dataSocket.recv(BUFLEN)
            if not recved:
                break
            print(' << ' + recved.decode() + '\n>>', end='')

if __name__ == '__main__':
    os.system("cls")
    print("you have connected him")
    Send().start()
    Get().start()

这样，服务器端和客户端就可以通过TCP协议进行双机通信了。\[1\]\[2\]
