本文實例講述了python實現超簡單端口轉發的方法。分享給大家供大家參考。具體如下：

代碼非常簡單，實現了簡單的端口數據轉發功能，用于真實環境還需要再修改一下。
代碼如下:#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"

希望本文所述對大家的Python程序設計有所幫助。
