我正在尝试制作一个简单的 Flash ActionScript3 程序，通过 PHP 脚本将一些文本保存到文本文件（在我的服务器上）。我希望 Flash 程序能够检测 PHP 脚本是否无法写入。现在我只是想让 Flash 跟踪从 PHP 收到的状态。我的以下代码基于我在网上找到的一些示例。

这是我的 Flash 代码：

import flash.net.*;
import flash.events.*;

var varLoader:URLLoader = new URLLoader;
var varURL:URLRequest = new URLRequest("http://xxxxxxxx/outputTest.php");
var submittedData:URLVariables=new URLVariables();
varURL.data = submittedData;
varURL.method = URLRequestMethod.POST;

submittedData.inputData = "ThisIsTheDataToBeSaved";
submittedData.FileName = "ThisIsTheFileName";
varLoader.addEventListener(Event.COMPLETE, fxnDoneSaving);
varLoader.load(varURL);

function fxnDoneSaving(evt:Event):void{
    trace("Done saving.");
    trace("Write status: "+String(evt.target.data.WasWritingSuccessful));
}

这是我的PHP代码：

<?php

$receivedFromFlashData = $_POST['inputData']; 
$receivedFromFlashFileName = $_POST['FileName']; 

$filename = $receivedFromFlashFileName . ".txt";
$myTextFileHandler = fopen($filename,"w"); 

if($myTextFileHandler)
    {$writeInTxtFile = @fwrite($myTextFileHandler,"$receivedFromFlashData");}      

fclose($myTextFileHandler); 

if ($writeInTxtFile)
    {echo "WasWritingSuccessful=success";}
else
    {echo "WasWritingSuccessful=failure";}

?>

当 Flash 到达最后的跟踪语句时，我收到以下错误：“ReferenceError: Error #1069: Property WasWritingSuccessful not found on String and there is no default value.”

请帮助我理解我做错了什么？谢谢！

您需要像这样指定dataFormat：varLoadervarLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
