python如何创建TCP服务端和客户端
本文实例为大家分享了python创建tcp服务端和客户端的具体代码，供大家参考，具体内容如下
1.服务端server
from socket import *
from time import ctime
HOST = ''
PORT = 9999
BUFSIZ = 1024
ADDR = (HOST, PORT)
tcpSerSock = socket(AF_INET, SOCK_STREAM) #创建套接字
tcpSerSock.bind(ADDR) #绑定IP和端口
tcpSerSock.listen(5) #监听端口，最多5人排队
while True:
print('waiting for connection...')
tcpCliSock, addr = tcpSerSock.accept() #建立连接
print('...connected from:', addr)
while True:
data = tcpCliSock.recv(BUFSIZ)
if not data:
break
content = '[%s] %s' % (bytes(ctime(), "utf-8"), data)
print(data)
print(type(content))
tcpCliSock.send(content.encode("utf-8"))
tcpCliSock.close()
tcpSerSock.close()
2.客户端client
from socket import *
HOST = '127.0.0.1' # or 'localhost'
PORT = 9999
BUFSIZ = 1024
ADDR = (HOST, PORT)
tcpCliSock = socket(AF_INET, SOCK_STREAM)
tcpCliSock.connect(ADDR)
while True:
data = input('> ')
if not data:
break
tcpCliSock.send(data.encode("utf-8"))
data = tcpCliSock.recv(BUFSIZ)
if not data:
break
print(data.decode("utf-8"))
tcpCliSock.close()
