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。
