多线程网络连接

客户端用多线程接受来自多用户的请求，且永不退出。

服务器端

#!/usr/bin/env python
#-*- coding:utf-8 -*-
import socket
import threading, time

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((‘127.0.0.1‘, 9999))
s.listen(5)
print ‘Waiting for connection...‘

def tcplink(sock, addr):
    print ‘Accept new connection from %s:%s...‘ % addr
    sock.send(‘Welcome!‘)
    while True:
        data = sock.recv(1023)
        time.sleep(1)
        if data == ‘exit‘ or not data:
            break
        sock.send(‘Hello, %s!‘ %data)
    sock.close()
    print ‘Connection from %s:%s closed.‘ % addr

while True:
    sock, addr = s.accept()
    #创建新进程来出来新的TCP连接
    t = threading.Thread(target=tcplink, args=(sock, addr))
    t.start()

客户端

#!/usr/bin/env python
import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((‘127.0.0.1‘, 9999))
print s.recv(1024)
for data in [‘Michael‘, ‘Tracy‘, ‘Sarah‘]:
    s.send(data)
    print s.recv(1024)
s.send(‘exit‘)
s.close()
