python网络编程示例(客户端与服务端)
client客户端
复制代码 代码如下:
if __name__ == '__main__':
import socket
import os
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('localhost', 8001))
import time
time.sleep(2)
sock.send('1')
print sock.recv(1024)
#os.system('pause')
#raw_input()
time.sleep(3)
sock.close()
server服务端
复制代码 代码如下:
if __name__ == '__main__':
import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('localhost', 8001))
sock.listen(5)
while True:
connection,address = sock.accept()
try:
connection.settimeout(5)
buf = connection.recv(1024)
if buf == '1':
connection.send('welcome to server!')
else:
connection.send('please go out!')
except socket.timeout:
print 'time out'
connection.close()
