最近在研究socket，感觉功能还是相当强大的说，client我用的是AS3，server我用的是python

server:

#coding:utf-8
import socket
mysock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serverAddr = ('192.168.6.112',54321)
mysock.bind(serverAddr)
mysock.listen(1)
j = True;
back = 'to client'
while j:
	a, b = mysock.accept()
	clientData = a.recv(16)
	print ('client:',b)
	print ('data:', clientData)
	a.sendall(bytes(back, 'utf-8'))
	j = False

client:

import flash.net.Socket;
import flash.events.Event;
import flash.utils.ByteArray;
import flash.events.ProgressEvent;

var b:ByteArray = new ByteArray;
b.writeMultiByte('toData','utf-8');

var so:Socket = new Socket;
so.addEventListener(Event.CONNECT,h);
so.addEventListener(ProgressEvent.SOCKET_DATA, r);
function h(E:Event){
	var s:Socket = E.currentTarget as Socket;
	s.writeBytes(b, 0, b.length);
	s.flush();
}

function r(E:ProgressEvent){
	var xx:Socket = E.currentTarget as Socket;
	trace (xx.readUTFBytes(E.bytesLoaded));
}

so.connect('192.168.6.112', 54321);
