本文通过Python实现了一个简单的Socket服务器与客户端交互示例。服务器监听本地8008端口并接受客户端连接，接收来自客户端的数据并根据不同条件发送响应。客户端连接服务器并发送指定数据，接收服务器返回的消息。

On Server:

# -*- coding: utf-8 -*-
#this is the server
import socket

if "__main__" == __name__:
    try:
        sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        print("create socket suc!")

        sock.bind(('localhost',8008))
        print('bind socket suc!')

        sock.listen(5)
        print('listen socket suc!')

    except:
        print("init socket err!")

    while True:
        print('listren for client...')
        conn,addr = sock.accept()
        print('get client')
        print(addr)

        conn.settimeout(5)
        szBuf = conn.recv(1024)
        byt = 'recv:' + szBuf.decode('gbk')
        print(byt)

        if '0' == szBuf:
            conn.send('exit')
        else:
            conn.send('welcome client!')

        conn.close()
        print('end of the service')

On Client:

import socket

if "__main__" == __name__:

    sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    sock.connect(('localhost',8008))
    sock.send(b'0')

    szBuf = sock.recv(1024)
    byt = 'recv:' + szBuf.decode('gbk')
    print(byt)

    sock.close()
    print('end of the connecct')
