Mina和swf文件通信。

 本文介绍使用java的Mina框架，来编写socket服务器，以及和swf文件直接进行socket连接。

需要用到mina2.0的jar包  大家自己去找吧。

废话不说，直接先上服务端代码：

main.java

import java.io.IOException;import com.game.action.StartGameHandler;import com.game.server.TcpServer;import com.game.service.InitGameService;public class main {public static void main(String[] string) throws Exception {new StartGameHandler();InitGameService.getService().init();//初始化信息TcpServer tcpServer = new TcpServer();tcpServer.serverStart();tcpServer.securityStart();}}

 ServerHandler .java

import org.apache.mina.common.IdleStatus;import org.apache.mina.common.IoAcceptor;import org.apache.mina.common.IoHandler;import org.apache.mina.common.IoSession;public class ServerHandler implements IoHandler{private IoAcceptor acceptor;private static ServerHandler handler = new ServerHandler();public static ServerHandler getInstance() {if(handler == null){handler = new ServerHandler();}return handler;}@Overridepublic void messageReceived(IoSession session, Object message) throws Exception {//在此地接收信息。}@Overridepublic void messageSent(IoSession session, Object message) throws Exception {// TODO Auto-generated method stub}@Overridepublic void sessionClosed(IoSession session) throws Exception {System.out.println("联机关闭"); return;}@Overridepublic void sessionCreated(IoSession session) throws Exception {System.out.println("联机创建了"); }@Overridepublic void sessionIdle(IoSession arg0, IdleStatus arg1) throws Exception {// TODO Auto-generated method stubSystem.out.println("用户连接了"); }@Overridepublic void sessionOpened(IoSession session) throws Exception {// TODO Auto-generated method stubreturn;}public IoAcceptor getAcceptor() {return this.acceptor;}public void setAcceptor(IoAcceptor acceptor) {this.acceptor = acceptor;}@Overridepublic void exceptionCaught(IoSession session, Throwable cause)throws Exception {System.out.println("出错了");   cause.printStackTrace();  }}

TcpServer.java

package com.game.server;import java.io.IOException;import java.net.InetSocketAddress;import java.nio.charset.Charset;import org.apache.mina.common.IoAcceptor;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.filter.codec.textline.LineDelimiter;import org.apache.mina.filter.codec.textline.TextLineCodecFactory;import org.apache.mina.filter.logging.LoggingFilter;import org.apache.mina.transport.socket.nio.NioSocketAcceptor;import com.game.action.GameHandler;public class TcpServer {public void serverStart(){IoAcceptor acceptor = new NioSocketAcceptor();   acceptor.getSessionConfig().setReadBufferSize(1024000);acceptor.getFilterChain().addLast( "logger", new LoggingFilter());   acceptor.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ),LineDelimiter.NUL,LineDelimiter.NUL)));   GameHandler handler =GameHandler.getInstance();acceptor.setHandler(handler);try {acceptor.bind(new InetSocketAddress(6060));System.out.println("TCP端口绑定: "+6060);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}System.out.println("TCP服务监听开始...... ");}public void securityStart(){IoAcceptor acceptor = new NioSocketAcceptor();   acceptor.getSessionConfig().setReadBufferSize(1024000);acceptor.getFilterChain().addLast( "logger", new LoggingFilter());   acceptor.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ),LineDelimiter.NUL,LineDelimiter.NUL)));   SecurityHandler handler =SecurityHandler.getInstance();acceptor.setHandler(handler);try {acceptor.bind(new InetSocketAddress(843));System.out.println("TCP端口绑定: "+843);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}System.out.println("TCP服务监听开始...... ");}}

 

安全策略端口监听：

SecurityHandler .java

import java.util.List;import org.apache.mina.common.IdleStatus;import org.apache.mina.common.IoAcceptor;import org.apache.mina.common.IoHandler;import org.apache.mina.common.IoSession;public class SecurityHandler implements IoHandler{private IoAcceptor acceptor;private  String securityWords = "<policy-file-request/>";private  final String securityXml = "<?xml version='1.0'?>" + "<cross-domain-policy>" + "<allow-access-from domain='*' to-ports='*'/>" + "</cross-domain-policy>";private static SecurityHandler handler = new SecurityHandler();public static SecurityHandler getInstance() {if(handler == null){handler = new SecurityHandler();}return handler;}@Overridepublic void messageReceived(IoSession session, Object message) throws Exception {System.out.println("843:"+message);session.write(securityXml+ "\0");}@Overridepublic void messageSent(IoSession session, Object message) throws Exception {// TODO Auto-generated method stub}@Overridepublic void sessionClosed(IoSession session) throws Exception {return;}@Overridepublic void sessionCreated(IoSession session) throws Exception {System.out.println("联机创建了"); }@Overridepublic void sessionIdle(IoSession arg0, IdleStatus arg1) throws Exception {// TODO Auto-generated method stubSystem.out.println("用户连接了"); }@Overridepublic void sessionOpened(IoSession session) throws Exception {// TODO Auto-generated method stubreturn;}public IoAcceptor getAcceptor() {return this.acceptor;}public void setAcceptor(IoAcceptor acceptor) {this.acceptor = acceptor;}@Overridepublic void exceptionCaught(IoSession session, Throwable cause)throws Exception {System.out.println("出错了");   cause.printStackTrace();  }}

客户端代码：

package { import flash.display.MovieClip; import flash.events.*; import flash.net.Socket; import flash.net.XMLSocket; import flash.system.Security; import flash.system.SecurityDomain;  public class SocketClient  {  private var socket:Socket;     private var xmlSocket:XMLSocket = new XMLSocket();  private var connect:Boolean = false;  private var _obj:Object =  this;  private static var client:SocketClient = null;  //private var ip:String = "192.168.1.101";  private var ip:String = "127.0.0.1";  private var surityStr = "xmlsocket://"+ip+":843";  private var port:int = 6060;  public function SocketClient() {   initApp();  }  /**单例模式**/  public static function getInstance():SocketClient{   if(client==null)   {    client = new SocketClient();   }   return client;  }  private function initApp():void{   if(!xmlSocket.connected)   {    initXMLSocket();      }  }                private function initXMLSocket() {   Security.loadPolicyFile(surityStr);   xmlSocket.connect(ip,port);      xmlSocket.addEventListener(Event.CONNECT,connectionFun);      xmlSocket.addEventListener(Event.CLOSE,closeFun);   }  public function setBackFunction(fun:Function){      xmlSocket.addEventListener(DataEvent.DATA,fun);  }  private function connectionFun(event:Event):void{      trace("已经成功连接到服务器\n");  }  /**   **设置回调方法   ***/  private function closeFun(event:Event):void{   trace("已经断开服务器\n");   client = null;  }     public function receiveMsg(event:DataEvent):void{      trace("接收到消息"+event.data);  }   public function removeListener(fun:Function) {   xmlSocket.removeEventListener(DataEvent.DATA ,fun);  }  /**   *向服务端发送 xml 数据   ***/  public function sendXml(xml:String):void{   try{    xmlSocket.send(xml.toString());      }catch(e:Error){    client = null;   }  } }}

实例化这个类之后，直接调用 sendXml("参数") 这个方法，即可发送socket消息。

Security.loadPolicyFile(surityStr);//这个是策略信息。

向843端口发送信息后，843端口返回策略信息，即能完成socket连接。

如果没有策略信息，是可以连接到6060端口，但是连接后，马上会断掉，所以无法进行socket通信。

注意：发布的时候，flash cs 要在发布配置里面 配置好“只访问网络”。

如果发布配置不设置好，前面的代码我测试是无法通过的。本地测试OK。只打开swf文件就无法正常通信。这点我折腾了很久。
