第一种：不传参，直接读取PHP文件。
btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
urlLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
urlLoader.load(new URLRequest(“http://localhost/as3/url2.php”));
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
var mydata:URLVariables=URLVariables((evt.currentTarget as URLLoader).data);
mytxt.text=”国家是:”+mydata.state+”n”;
mytxt.text+=”var1是:”+mydata.var1;
}
PHP端代码：
<?php
$state=”中华人民共和国”;
$var1=”我爱你”;
echo “state=”.$state.”&var1=”.$var1;
?>
第二种：无参数，读取XML文件。
btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
urlLoader.load(new URLRequest(“data.xml”));
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
var mydatas:XML=XML((evt.currentTarget as URLLoader).data);
mytxt.text=mydatas.c1.toString()+”,”+mydatas.c2.toString();
}
xml文件内容：
<?xml version=”1.0″ encoding=”utf-8″?>
<cities>
<c1>北京</c1>
<c2>上海</c2>
</cities>
上述代码结果：
北京,上海
第三种：无参数，PHP生成XML文件。
btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
urlLoader.load(new URLRequest(“http://localhost/as3/xml.php”));
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
var mydatas:XML=XML((evt.currentTarget as URLLoader).data);
mytxt.text=mydatas.c1.toString()+”,”+mydatas.c2.toString();
}
php端:
<?php
//你可以使用php操作xml的函数
//这里为了简单起见只是echo出来
echo “<?xml version=”1.0″ encoding=”utf-8″?>”;
echo “<cities>”;
echo “<c1>北京</c1>”;
echo “<c2>上海</c2>”;
echo “</cities>”;
?>
第四种：GET方法传参
System.useCodePage=true;
btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
var request:URLRequest=new URLRequest();
request.url=”http://www.baidu.com/s”;
request.method=URLRequestMethod.GET;
request.data=”wd=flash”;
urlLoader.load(request);
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
mytxt.text=(evt.currentTarget as URLLoader).data;
}
第五种：POST方法传参
System.useCodePage=true;
btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
var request:URLRequest=new URLRequest();
var vars:URLVariables=new URLVariables();
vars.wd=”flash”;
request.url=”http://www.baidu.com/s”;
request.method=URLRequestMethod.GET;
request.data=vars;
urlLoader.load(request);
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
mytxt.text=(evt.currentTarget as URLLoader).data;
}
这里data是URLVariables是值对，注意区别。
