Flex HttpService重用2

HttpService工具类：

package common
{
	import mx.controls.Alert;
	import mx.rpc.AsyncToken;
	import mx.rpc.events.FaultEvent;
	import mx.rpc.http.HTTPService;

	public class HttpServices
	{
		private var http:HTTPService;
		private var _host:String;
		private static var https:HttpServices;
		
		public function HttpServices()
		{
			http = new HTTPService();
		}

		public function set host(value:String):void
		{
			_host = value;
		}

		public function sendHttpSer(url:String,
									local:String="/zport/dmd/YDBackScript/asset_handler?callMethod=",
									json:String="",
									format:String="e4x",
									contentType:String="application/x-www-form-urlencoded"):AsyncToken
		{
			local = _host + local;
			http.url = local + url;
			http.resultFormat = format;
			http.method = "POST";
			http.showBusyCursor = true;
			http.contentType = contentType;
			return json.length>0 ? http.send(json) : http.send();
		}
		
		public function sendJsonService(json:String,
									   url:String="/zport/dmd/Events/evconsole_router",
									   format:String="object"):AsyncToken
		{
			return sendHttpSer(url,"",json,format,"application/json; charset=utf-8");
		}
		
		public static function getInstance():HttpServices
		{
			if(!https)https = new HttpServices();
			return https;
		}
	}
}

Responder工具类：

package common
{
	import mx.controls.Alert;
	import mx.rpc.AsyncResponder;
	import mx.rpc.AsyncToken;
	import mx.rpc.events.FaultEvent;

	public class ResponserUtils
	{
		public function ResponserUtils()
		{
		}
		
		public static function responderHandler(token:AsyncToken,resultHandler:Function):void
		{
			var responder:AsyncResponder = new AsyncResponder( resultHandler, faultHandler );
			token.addResponder( responder );
		}
		
		private static function faultHandler( event:FaultEvent, token:Object=null ):void
		{
//			Alert.show("网络服务未能正常访问，请联系管理员解决，:)","错误提示");
			trace( "FAULT: " + event.fault.message );
		}
	}
}

调用方法：

var tokens:AsyncToken = https.sendHttpSer("getAssetsClassReferenceByAssetID&classID="+classID+"&layer="+1);
ResponserUtils.responderHandler(tokens,getAssetsRelationship);

回调函数：

private function getAssetsRelationship(e:ResultEvent,token:Object=null):void
{
}
