serverSocket与socket的使用

1、使用serverSocket建立服务端：

   首先创建一个 serverSocket(一定要是个全局变量)

      private var server:ServerSocket;

   绑定到指定的本地址和端口

      server.bind( 6666, "119.138.64.241" );

   侦听绑定的IP地址和端口上的TCP连接 

      server.listen();

    当有客户端连接时（当客户端尝试连接到服务器套接字时，ServerSocket 对象调度 ServerSocketConnectEvent 对象）

      server.addEventListener(ServerSocketConnectEvent.CONNECT, onConnect);

15                 {
16                     server = new ServerSocket();
17                 }

23                 else
24                 {
25                     try
26                     {
27                         //绑定到指定的本地地址和端口
28                         server.bind( 6666, "119.138.64.241" );

31                         server.addEventListener(ServerSocketConnectEvent.CONNECT, onConnect);
32                     }
33                     catch(e:*)
34                     {
35                         trace( e );

42             {
43                 //trace( "connect..." );
44                 var socket:Socket = event.socket;
45                 socket.addEventListener(ProgressEvent.SOCKET_DATA, onReceive);
46                 
47                 outputTxt.text += "connect..." +"\n";

68     <mx:TextArea id="outputTxt" left="10" right="10" top="59" bottom="10"/>

70 </mx:WindowedApplication>

2、使用socket建立客户端
    创建 scoket 对象

    private var socket:Socket;

    socket = new Socket();

   连接服务端（地址和端口要和服务端一到致）

   socket.connect( "119.138.64.241", 6666 );

   侦听socket的连接

   socket.addEventListener(Event.CONNECT, onConnect );
