Flex 与Python之间Socket通讯

 查阅Adobe提供的API文档可以了解到，XMLSocket提供了四个公开方法: 
    1、XMLSocket(host:String=null,port:int=0)--创建一个新的XMLSocket对象。 
    2、close():void--关闭一个XMLSocket。 
    3、connect(host:String,port:int):void--连接到指定的TCP端口。 
    4、send(object:*):void--将数据发送到连接服务端。

客户端Flex代码：

服务器端Python代码：

    #!/usr/bin/env python    #coding=utf-8    from socket import *    from time import ctime      HOST=‘localhost’       PORT=21567      BUFSIZ=4096      ADDR=(HOST, PORT)      tcpSerSock = socket(AF_INET, SOCK_STREAM)    tcpSerSock.bind(ADDR)    tcpSerSock.listen(5)     while True:       print ‘waiting for connection…’        tcpCliSock, addr = tcpSerSock.accept()       print ‘…connected from:’, addr          while True:            data = tcpCliSock.recv(BUFSIZ)            if not data:                break            tcpCliSock.send(‘[%s] %s’ % (ctime(), data))               tcpCliSock.close()   tcpSerSock.close()
