As3下的通信(Red5)

代码如下:

client:

FLASH

var nc:NetConnection = new NetConnection();
nc.client = this;
nc.objectEncoding = flash.net.ObjectEncoding.AMF0;//注意这句话(不加的话  同步事件没有被触发)

nc.connect("rtmp://192.168.1.109/wxgameflashserver");

var so:SharedObject = SharedObject.getRemote("gamemsg", nc.uri, false);
so.connect(nc);

nc.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
so.addEventListener(SyncEvent.SYNC,newMessageHandler);
sendButton.addEventListener(MouseEvent.CLICK,sendMessage);

function netStatusHandler(Evt:NetStatusEvent){

        if (Evt.info.code == "NetConnection.Connect.Success") {
              history.appendText("连接成功!");
        }
        if (Evt.info.code == "NetConnection.Connect.Failed") {
              history.appendText("连接失败!");
        }
}

function newMessageHandler(event:SyncEvent):void{
    var infoObj:Object=event.changeList;
    for (var i = 0; i<infoObj.length; i++) {
        var info = infoObj[i];
        if (info.name != undefined) {
             if(info.code=="change"){
                  history.appendText(so.data.chatMessage + "/n");
             }
        }
    }
}

function sendMessage(event:MouseEvent):void{
    so.setProperty("chatMessage",message.text);
    so.setDirty("chatMessage");
    history.appendText(message.text + "/n");
    message.text="";
}

 

Server:

java

Application.java

package com.zhangchao;

import org.red5.server.adapter.ApplicationAdapter;
import org.red5.server.api.IScope;
import org.red5.server.api.so.ISharedObject;

public class Application extends ApplicationAdapter{

    private ISharedObject iso;
    private String chatMessage = "" ;
    public String getChatMessage() {
        return chatMessage;
    }

    public void setChatMessage(String chatMessage) {
        this.chatMessage = chatMessage;
    }

    @Override
    //该方法初始化时执行一次
    public synchronized boolean start(IScope scope) {
        this.createSharedObject(scope, "gamemsg", true);
        iso = this.getSharedObject(scope, "gamemsg",false);// persistent==false
        iso.beginUpdate();
        iso.setAttribute("chatMessage", chatMessage);
        iso.endUpdate();
        return super.start(scope);
    }
}

需要注意的几个地方:

1.iso = this.getSharedObject(scope, "gamemsg",false);// persistent==false

2.nc.objectEncoding = flash.net.ObjectEncoding.AMF0;//注意这句话(不加的话  同步事件没有被触发)

3.Flash player 9  与10.0 播放器也有区别

===================================================

javascript 与 flash 互通

4. javascript 到 flash

//加载swf 后面的参数列表
var roleid:String;
roleid=loaderInfo.parameters["roleid"];

5. flash 到 javascript 

> getURL("javascript:quickreg();");   As2

> getURL(http://www.163.com/, "_parent");  As2

>navigateToURL(new URLRequest(http://www.baidu.com)); As3

通信机制代码结束 –>

id一定要加 不然 IE下调用不了 Javascript 脚本 报错为 : NULL为空或不是对象

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

使用javascript调用Flash中的方法

js:
var flash = document.getElementById( "newFlash" );
flash.showNanyhXG();
Flash:
ExternalInterface.addCallback ("showNanyhXG", this, showNanyhXG);
