FLEX 与现有开发语言的通信全面解析

以下介绍几种最为常见和实用的FLEX与现有开发语言通信的方法：
1.C#
2.PHP
3.JAVA
1.Flex与C#通信(.net开发中常用)
Flex端代码:
   public static function SendMessage(objXML:XML,objResultHandle:Function):void
   {
        var objHttpService:HTTPService = new HTTPService();
        objHttpService.url = "http://localhost:8085/upfiledata.aspx";   //发送到的C#页面
        objHttpService.resultFormat = "e4x";
        objHttpService.addEventListener(ResultEvent.RESULT,objResultHandle);
        objHttpService.method = "POST";
        objHttpService.contentType = "application/xml";
        objHttpService.send(objXML);  //objXML 要发送的数据
  }
   public function objResultHandle(evt:ResultEvent):void
   {
            evt   //接收到的数据
   }
C#端:
    protected void Page_Load(object sender, EventArgs e)
    {
                XmlDocument objProtocolDom = new XmlDocument();
                objProtocolDom.Load(Request.InputStream);  //objProtocolDom接收来自Flex端所发送的数据流
                Response.ContentType = "text/xml";
                Response.Write(objResultDom.OuterXml);  //向Flex端下发数据流
    }
2.Flex与php通信
Flex代码:
<?xml version="1.0" encoding="utf-8"?> 
<mx:Application xmlns:mx="http://www.adobe.co
