即时通信(RPC)的Rtmp实现--配置篇

step 1: 首先要确定RTMP的端口，可以利用netstat -an来查看

step 2: 修改services-config.xml，确保有rtmp的相关节点：

<channel-definition id=

"my-rtmp"class

=

"mx.messaging.channels.RTMPChannel"

>
 <endpoint uri=

"rtmp://{server.name}:8323"class

=

"flex.messaging.endpoints.RTMPEndpoint"

/>
 <properties>
  <idle-timeout-minutes>20</idle-timeout-minutes>
 </properties>
</channel-definition>

step 3: 在网站新建apps目录，并添加MyChatRoom文件夹作为应用程序目录

step 4: 定义MyChatApp类继承自FluorineFx.Messaging.Adapter.ApplicationAdapter，并定义供客户端调用的方法GetResult()

step 5: 在应用程序目录(MyChatRoom)里添加配置文件app.config，内容如下：

<?xml version=

"1.0"

 encoding=

"utf-8"

?>
<configuration>
 <application-handler type=

"ServiceLibrary8.MyChatApp"

/>
</configuration>

step 6: 新建Flex项目，分为 连接rtmp 和 调用方法 两部分来实现

服务器端：

using System;
using System.Collections.Generic;
using System.Text;
using FluorineFx.Messaging.Adapter;
namespace ServiceLibrary8
{
    

public class

 MyChatApp : ApplicationAdapter
    {
        

public

string GetResult(string name, int age)
        {
            

return

 name + 

" is "

 + age + 

" years old"

;
        }
    }
}

Flex端：

<?xml version=

"1.0"

 encoding=

"utf-8"

?>
<mx:Application xmlns:mx=

"http://www.adobe.com/2006/mxml"

 layout=

"absolute"

>
 <mx:Button x=

"211"

 y=

"69"

 label=

"连接RTMP"

 click=

"onConnectClick()"

 />
 <mx:Button x=

"190"

 y=

"113"

 label=

"调用RTMP提供的方法"

 click=

"onFunctionClick()"

 />
 <mx:Label id=

"lblResult"

 x=

"230"

 y=

"31"

 text=

"Label"

/>
 
 <mx:Script>
