Python Socket

套接字模块是一个非常简单的基于对象的接口,它提供对低层BSD套接字样式网络的访问。使用该模块可以实现客户机和服务器套接字。要在python 中建立具有TCP和流套接字的简单服务器,需要使用socket模块。利用该模块包含的函数和类定义,可生成通过网络通信的程序。
服务端 server.py
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()
客户端 client.py
if __name__ == '__main__':
import socket
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)
sock.close()
