Flash AS3与php通信

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 "";
echo "";
echo "1.jpg";
echo "2.jpg";
echo "
";
?>

 

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。
