与c/c++ socket编程对照见

server：

import socketPORT    = 9999BACKLOG = 5MAXLINE = 1024listenfd = 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()

client:

import socketaddr = '127.0.0.1'port = 9999sockfd = 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:		breakdata = ''.join(buf)print datasockfd.close()
