初学脚本语言python,测试可用的tcp通讯程序:


服务器:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import socket
import threading
import time

def tcplink(sock, addr):
    print('Accept new connection from %s:%s...' % addr);
    sock.send(b'Welcome!!!');
    while True:
        data = sock.recv(1024);
        time.sleep(1);
        if not data or data.decode('utf-8') == 'exit':
             break;
        sock.send(b'Hello, %s!' % data);
    sock.close();
    print('Connection from %s:%s closed.' % addr);


if __name__ == "__main__":

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM);

    s.bind(('127.0.0.1', 9090));
    s.listen(8); #监听8个客户端;
    print('waiting for connection...');

    while True:
        sock, addr = s.accept();
        t = threading.Thread(target=tcplink, args=(sock,addr));
        t.start();

客户端:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM);
s.connect(('127.0.0.1', 9090));
print(s.recv(1024).decode('utf-8'));
for data in [b'lk', b'aa', b'bb']:
    s.send(data);
    print(s.recv(1024).decode('utf-8'));
s.send(b'exit');
s.close();
