Python Socket编程实现的简单tcp迭代服务器

服务器：

import socket

PORT = 9999
BACKLOG = 5
MAXLINE = 1024

listenfd = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
listenfd.bind(('',PORT))
listenfd.listen(BACKLOG)

while True:
connfd, connaddr = listenfd.accept()
print 'a new connection'
buf = []
buf = connfd.recv(MAXLINE)
print buf
connfd.send('Hello,this is server')
connfd.close()

客户端:

import socket

addr = '127.0.0.1'
port = 9999
sockfd = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sockfd.connect((addr, port))
sockfd.send('Hello,this is client')
buf = []

while True:
recv_data = sockfd.recv(1024)
if recv_data:
buf.append(recv_data)
else:
break

data = ''.join(buf)
print data
sockfd.close()
