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()
