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。
代码如下:
#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。
