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:未发送xlsexport.php的http://[sitename].com/xls.php?id=456 id变量

代码只是"filename = xlsexport“变量产生一个变量，我想发送一个不同的"id = 4545 & pass = 87665”

Answer 1

你可以通过使用URLVariables类来做你想做的事情。

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.');
        }
    }
}

并使用以下代码行在Adobe Flash项目(*.fla文件)的时间线中调用它。

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

请记住，如果要添加多个URL变量，则必须对每个URL变量使用以下代码行：

nameOfYourURLVariablesInstance.yourUrlVariableName = yourUrlVariableValue;

如下所示：

urlVars.id = 456;

在示例ActionScript 3类文件中。

此外，您还可以从以下地址下载示例项目：

Answer 2

尝试将URL构造为字符串。

var _id:int = 456;
var _pass:int = 87665;
var _requestString:String = "http://" + sitename + ".com/xlsexport.php?id=" + _id + "&pass=" + _pass;

var fileRequest:URLRequest= new URLRequest(_requestString);

PS。还要确保使用相同的var名称(sitename或filename)。
