客戶端程序代碼：

# Client program from socket import * # Set the socket parameters host = "localhost" port = 21567 buf = 1024 addr = (host,port) # Create socket UDPSock = socket(AF_INET,SOCK_DGRAM) def_msg = "===Enter message to send to server==="; print "/n",def_msg # Send messages while (1): data = raw_input('>> ') if not data: break else: if(UDPSock.sendto(data,addr)): print "Sending message '",data,"'....." # Close socket UDPSock.close()

 

服務器端程序代碼：

# Server program from socket import * # Set the socket parameters host = "localhost" port = 21567 buf = 1024 addr = (host,port) # Create socket and bind to address UDPSock = socket(AF_INET,SOCK_DGRAM) UDPSock.bind(addr) # Receive messages while 1: data,addr = UDPSock.recvfrom(buf) if not data: print "Client has exited!" break else: print "/nReceived message '", data,"'" # Close socket UDPSock.close()
