Flex's HTTPService 数据交互代码大集合

今天把常用的后台代码整理一下，教程就不用写了，我相信要是涉及到这方面的人，应该不用手把手教的，整理的代码主要有ＰＨＰ，ＡＳＰ．ＮＥＴ，ＪＡＶＡ．够爽吧．最近也正在整理ＦＭＳ２.０应用的各种语言版本的例子，以后可能会爆出来．

先分一下类：HTTPService主要分为普通网页格式调用和，ＸＭＬ方式调用．

Flex(普通形式):

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
    layout="absolute"
    backgroundColor="#FFFFFF"
    backgroundAlpha="0">
	<mx:Script>

	        public function handlePlain(event:ResultEvent):void
	        {
	            shippingOptions.text = event.result.toString();
	        }

	        public function handleFault(event:FaultEvent):void
	        {
	           Alert.show(event.fault.faultString, "Error");
	        }
		]]>

Flex(XML格式):

            {
                shippingInfo = event.result.option as XML;
            }

	        public function handleFault(event:FaultEvent):void
	        {
	           Alert.show(event.fault.faultString, "Error");
	        }
		]]>
	</mx:Script>

    <mx:HTTPService result="handleXML(event);" fault="handleFault(event);" id="xmlRPC" resultFormat="e4x"
