python实现超简单端口转发的方法_Python

本文实例讲述了python实现超简单端口转发的方法。分享给大家供大家参考。具体如下：

代码非常简单，实现了简单的端口数据转发功能，用于真实环境还需要再修改一下。

	#tcp server 

	import socket 

	host = '127.0.0.1'          #Local Server IP 

	host2 = '127.0.0.1'   #Real Server IP 

	port = 6001 #Local Server Port 

	port2 = 7001 #Real Server Port 

	def ProcData(data): 

	    return data 

	    #add more code.... 

	print "Map Server start from " + host + ":" + str(port) +" to " + host2 + ":" + str(port2) +"\r\n" 

	server = socket.socket(socket.AF_INET,socket.SOCK_STREAM) 

	server.bind(('127.0.0.1',port)) 

	print "127.0.0.1 Server start at "+ str(port) +"\r\n" 

	client = socket.socket( socket.AF_INET, socket.SOCK_STREAM ) 

	client.connect((host2,port2)) 

	print host +" Client connect to " + host2 + ":"+str(port2)+"\n" 

	server.listen(5) 

	ss, addr = server.accept() 

	print 'got connected from',addr 

	while 1: 

	    msg = ss.recv(20480) 

	    print "Get:"+repr(msg)+"\r\n" 

	    client.send(msg) 

	    #print "Client send data %s to "%repr(msg) 

	    buf=client.recv(20480) 

	    #print "Client recv data %s from "%repr(buf) 

	    ss.send(buf) 

	    print "Send:"+repr(buf)+"\r\n"

希望本文所述对大家的Python程序设计有所帮助。
