HttpService 入门例子

Flex HttpService入门例子，最好使用FireFox浏览器(能看到图片)

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="so_hs.send()">
	
	<mx:HTTPService id="so_hs" url="http://rss.news.sohu.com/rss/guonei.xml"/>
	
	<mx:Panel x="64" y="10" width="929" height="275" layout="absolute" title="{so_hs.lastResult.rss.channel.title}" fontSize="13">
		<mx:AdvancedDataGrid id="dgPosts" dataProvider="{this.so_hs.lastResult.rss.channel.item}" designViewDataType="flat" width="100%" height="100%">
			<mx:columns>
				<mx:AdvancedDataGridColumn headerText="标题" dataField="title"/>
				<mx:AdvancedDataGridColumn headerText="日期" dataField="pubDate"/>
			</mx:columns>
		</mx:AdvancedDataGrid>
		
	</mx:Panel>
	<mx:TextArea x="64" y="293" htmlText="{this.dgPosts.selectedItem.description}" width="929" height="273" fontSize="13"/>
	
	<mx:LinkButton x="921" y="574" id="openLinkButton" label="详细内容" click="navigateToURL(new URLRequest(this.dgPosts.selectedItem.link))" fontSize="12"/>
	
</mx:Application>
