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);
