现在谈到AS3与PHP的交互,第一反应都会想到AMF
?
其实AMF也不过是利用PHP或者其他语言来写的一个信息后台罢了,
?
回归到原始,无非通信还是这几种方法。
?
(1)直接读取
php:
<?
$state="开始接收";
$var1="收到";
echo "state=".$state."&var1=".$var1;
?>
?
as:
//btn是个按钮 txt是动态文本,在flash里面直接创建就OK
btn.addEventListener(MouseEvent.CLICK,loadMss);
txt.text="loading...";
function loadMss(e:MouseEvent):void
{
?? ??? var urlLoader:URLLoader=new URLLoader();
?????? mssLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
??????mssLoader.load(new URLRequest("http://localhost/as3/admin.php"));//这里就是php文件的地址
?????? mssLoader.addEventListener(Event.COMPLETE,completeFun);
}
function completeFun(e:Event):void
{
?? ??? var loadData:URLVariables=URLVariables((e.currentTarget as URLLoader).data);
???????txt.text="正在:"+loadData.state+"n";
?????? txt.text+="接收情况:"+loadData.var1;
}
(2)读取PHP生成的xml
php:
<?
//这里只是简单的echo出来了
echo "<?xml version="1.0" encoding="utf-8"?>";
echo "<pics>";
echo "<p1>1.jpg</p1>";
echo "<p2>2.jpg</p2>";
echo "</pics>";
?>
?
as:
//btn是个按钮 txt是动态文本,在flash里面直接创建就OK
btn.addEventListener(MouseEvent.CLICK,loadMss);
function loadMss(e:MouseEvent):void
{
?? ??? var urlLoader:URLLoader=new URLLoader();
???????xmlLoader.load(new URLRequest("http://localhost/as3/xml.php"));//这里就是php文件的地址
???? ? xmlLoader.addEventListener(Event.COMPLETE,completeFun);
}
function completeFun(e:Event):void
{
?? ??? var loadData:XML=XML((e.currentTarget as URLLoader).data);
???????txt.text=loadData.toString();
}
(3)通过GET传出参数
?
//btn是个按钮 txt是动态文本,在flash里面直接创建就OK
System.useCodePage=true;
btn.addEventListener(MouseEvent.CLICK,loadMss);
function loadMss(e:MouseEvent):void
{
?? ??? var getLoader:URLLoader=new URLLoader();
????? var request:URLRequest=new URLRequest();
????? ?request.url="http://enatool.com/something.php";//这里是接收参数的地址
????? ?request.method=URLRequestMethod.GET;//传出方法
????? ?request.data="s=1";//传出具体的信息
?????? getLoader.load(request);
?????? getLoader.addEventListener(Event.COMPLETE,completeFun);
}
function completeFun(e:Event):void
{
??? txt.text=(e.currentTarget as URLLoader).data;
}
?
(4)通过POST传参
//btn是个按钮 txt是动态文本,在flash里面直接创建就OK
System.useCodePage=true;
btn.addEventListener(MouseEvent.CLICK,loadMss);
function loadMss(e:MouseEvent):void
{
?? ??? var postLoader:URLLoader=new URLLoader();
????? ?var request:URLRequest=new URLRequest();
????? var vars:URLVariables=new URLVariables();
????? ?vars.s1="flash";
????? ?vars.s2="flex";
?????? request.url="http://enatool.com/something.php";
?????? request.method=URLRequestMethod.POST;
??????request.data=vars;//这里的data可以是一个Object,或者Array
?????? postLoader.load(request);
?????? postLoader.addEventListener(Event.COMPLETE,completeFun);
}
function completeFun(e:Event):void
{
??? txt.text=(e.currentTarget as URLLoader).data;
}
和php或者类似asp,.net的信息交互都是这样。所以说不要把交互看的那么难。
