FMS 4.5 + Flex mobile 之 Hello World

实例详细步骤：

?

1. 安装FMS 4.5，启动FMS 服务，安装目录applications下创建文件夹HelloFms

比如：D:Program FilesAdobeFlash Media Server 4.5applicationsHelloFms

?

2.HelloFms目录下创建main.asc，编写FMS服务器端脚本，保存成utf-8编码

main.asc脚本如下：

?

// 有客户连接
application.onConnect = function(client) {	
	// 接受连接
	application.acceptConnection(client);
	// 输出一个信息，这个信息可以在fms的admin工具里看到
	trace("HelloFMS接受连接");
}

//客户断开时
application.onDisconnect = function(client) {
	trace( "客户已断开");
}

//客户发布流时
application.onPublish = function(client,myStream) {
	trace(myStream.name + "开始发布" + application.name);
}

//取消发布时
application.onUnpublish = function( client,myStream ) {
	trace(myStream.name + " 停止发布"  );
}

Client.prototype.serverHelloMsg = function(helloStr){
	trace(helloStr);
	return "Hello," + helloStr + "!";
}
  

3.启动FlashBuilder 4.6，创建Flex手机工程，工程名称HelloFms，目标平台Google Android，注意CAMERA和RECORD_AUDIO权限配置

HelloFms-app.xml如下：

<?xml version="1.0" encoding="utf-8" standalone="no"?>

5.配置成模拟器运行，如果电脑正常连接摄像头，则Android手机模拟器上可以看到摄像头抓取的图像。本人测试通过。

控制台运行结果：

[SWF] HelloFms.swf - 解压缩后为 2,772,803 个字节
NetConnection.Connect.Success
服务端返回内容：Hello,Hello FMS!!
[卸装 SWF] HelloFms.swf

?

6.注意不要将FMS的live例子中的main.far文件拷贝到HelloFms目录内，否则会报错：NetConnection.Call.Failed,描述信息是Method not found (serverHelloMsg).

??? 如果还是仍然报错，试试重启FMS服务来解决这个问题。
