基于MVC模式的Flash Remoting类

为方便自己，我特意用MVC模式改写了Flash Remoting类，适用于AS2.0。但愿对大家还有些用。

一、RemotingModel 父类

** 
*   @class RemotingModel  
*   @author Flying 
*   @copyright 2006 riafan 
*/ 
import mx.remoting.Service; 
import mx.services.Log; 
import mx.remoting.PendingCall;; 
import mx.rpc.RelayResponder; 
import mx.rpc.FaultEvent; 
import mx.rpc.ResultEvent; 
import mx.remoting.debug.NetDebug; 
import mx.events.EventDispatcher; 
  
class com.riafan.RemotingModel { 
    private var gatewayURL:String; 
    private var servicePath:String; 
    private var svc:Service; 
    public var addEventListener:Function; 
    private var removeEventListener:Function; 
    private var dispatchEvent:Function; 
    private var dispatchQueue:Function; 
  
    /** 
    * Constructor 
    *  
    *   @param      $gatewayURL gateway URL 
    *   @param      $serviceName    service name 
    *   @param      $uid        username 
    *   @param      $pwd        password 
    * 
    */
    public function RemotingModel($gatewayURL, $serviceName, $uid, $pwd)  
    {        
        // initialize as a broadcaster 
        EventDispatcher.initialize(this); 
          
        // create a new service 
        svc = new Service ($gatewayURL, null, $serviceName, null, null); 
          
        // credentials 
        if ($uid != undefined && $pwd != undefined) { 
            svc.connection.setCredentials($uid, $pwd); 
        }    
    } 
    /** 
    * Global fault event 
    */
    private function handleRemotingModelError(fault:FaultEvent):Void  
    { 
        mx.remoting.debug.NetDebug.trace({level:"None", message:"Error: " + fault.fault.faultstring }); 
    } 
    /** 
    * Event dispatcher 
    *  
    *   @param      $data       data 
    *   @param      $type       event type 
    * 
    */
    private function dispatch($data, $type) 
    { 
        // broadcast message 
        var eventObj:Object={target:this,type:$type} 
        eventObj.data = $data; 
        dispatchEvent(eventObj); 
    } 

二、RemotingView父类

/** 
*   @class RemotingView  
*   @author Flying 
*   @copyright 2006 riafan 
*/
import mx.events.EventDispatcher; 
class com.riafan.RemotingView   
{ 
    private var target:MovieClip; 
    public var addEventListener:Function; 
    public var removeEventListener:Function; 
    public var dispatchEvent:Function; 
    public var dispatchQueue:Function; 
    /** 
    * Constructor 
    * 
    *   @param  mc  target (target timeline: _root || a mc) 
    */
    public function RemotingView ($target:MovieClip)  
    { 
        target = $target; 
          
        // initialize as a broadcaster 
        EventDispatcher.initialize(this); 
    }    
    /** 
    * Event dispatcher 
    *  
    *   @param      $data       data 
    *   @param      $type       event type 
    * 
    */
    private function dispatch($data, $type) 
    { 
        // broadcast message 
        var eventObj:Object={target:this,type:$type} 
        eventObj.data = $data; 
        dispatchEvent(eventObj); 
    } 
}

实际应用中，如果我们的项目并不复杂，就没有必要写父类了。
