actionscript-3 - As3 FileReference 下载动态 url

Question

As3 FileReference 下载动态url 不发送变量数据； 示例:

downloadXls.buttonMode=true;
import flash.net.FileReference;
import flash.events.Event;

var localRef:FileReference;
var fileRequest:URLRequest= new URLRequest("http://[sitename].com/xlsexport.php?id=456");
downloadXls.addEventListener(MouseEvent.CLICK,downloadXlsH);
function downloadXlsH(event:MouseEvent):void{
    localRef = new FileReference();
    localRef.addEventListener(Event.COMPLETE, completeHandler);
    localRef.download( fileRequest, 'myfile.xls' );
}
function completeHandler(e:Event):void{
    trace('OK. Dosya Kaydedildi.');
}

问题:http://[sitename].com/xls.php?id=456 id 变量不发送 xlsexport.php

代码只是“filename = xlsexport”变量产生一个我要发送不同的变量“id = 4545 & pass = 87665”

Answer 1

您可以使用 URLVariables 类做您想做的事。

创建一个 ActionScript 3 类文件 (*.as) 并在其中粘贴以下代码:

package
{
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.net.FileReference;
    import flash.net.URLRequest;
    import flash.net.URLRequestMethod;
    import flash.net.URLVariables;

    public class Download extends Sprite
    {
        var localRef:FileReference;
        var urlVars:URLVariables;
        var fileRequest:URLRequest;

        public function Download(downloadXls:*)
        {
            downloadXls.buttonMode=true;
            downloadXls.addEventListener(MouseEvent.CLICK,downloadXlsH);
        }

        private function downloadXlsH(event:MouseEvent):void
        {
            localRef = new FileReference();
            localRef.addEventListener(Event.COMPLETE, completeHandler);

            urlVars = new URLVariables();
            urlVars.id = 456;

            fileRequest = new URLRequest();
            fileRequest.method = URLRequestMethod.GET;
            fileRequest.data = urlVars;
            fileRequest.url = "http://[sitename].com/xlsexport.php";

            localRef.download(fileRequest);
        }

        private function completeHandler(e:Event):void
        {
            trace('OK. Dosya Kaydedildi.');
        }
    }
}

并使用以下行在您的 Adob​​e Flash 项目(*.fla 文件)的时间轴中调用它。

import Temp_Example4;
var temp:Temp_Example4 = new Temp_Example4(downloadXls);

请记住，如果您想添加多个 URL 变量，则必须为每个 URL 变量使用以下代码行:

nameOfYourURLVariablesInstance.yourUrlVariableName = yourUrlVariableValue;

像这样:

urlVars.id = 456;

在示例 ActionScript 3 类文件中。
