傳說中這樣比較高效～～

#include <stdlib.h>
#include <stdio.h>
#include "AS3.h"

//供AS調用的函數，args即為AS傳入給C函數的參數

    AS3_ArrayValue(args, "IntType, IntType", &a, &b);
    
    //計算a, b之和，轉換為AS裡的Int數據類型並返回之
    return AS3_Int(a+b);
}

int main()
{
    //定義一個公開給AS調用的函數
    AS3_Val myMethod = AS3_Function(NULL, myfun);

    //創建一個持有該函數引用的Object
    AS3_Val result = AS3_Object("myfun:AS3ValType", myMethod);

    //Release
    AS3_Release(myMethod);

    //告知初始化完成，此方法不會返回
    AS3_LibInit(result);

    //永遠不會執行到這裡
    return 0;

輸出JSON格式的字符串為：

     "phone":"020-39322849",

Q : 可以在Flex里获取GET参数么？比如某SWF文件的请求地址为http://….test.swf ? username=Oscar，该如何获取username参数的值呢？

A : 可以的，用mx.core.Application类的parameters属性可以获取附加在地址后面的参数，就拿上面的地址为例：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
creationComplete="init();">
    <mx:Script><![CDATA[
        import mx.controls.Alert;
        private function init():void{
            Alert.show(this.parameters.username,"Username");
        }
    ]]></mx:Script>
</mx:Application>
