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()
