Question

我将一个文本文件嵌入到我的Flex项目中，并使用以下代码读取其内容：

[Embed(source = "../../data/abc.txt", mimeType = "application/octet-stream")]
private var r_Abc:Class;

...

var xx:ByteArray = new r_Abc();
var abc:String = xx.toString();

该文件的内容是abc。问题是从文件加载的字符串与其他字符串不可比，即使在调试器中打印或查看时（在FlashDevelop中）它似乎完全正常。

trace(abc);  // abc
trace("abc" == abc);   // false

如何将其转换为正确的字符串？我尝试使用字符串方法（如substring）来创建副本，但这似乎不是解决方案。

这是我的样本：

<?xml version="1.0" encoding="utf-8"?>
<s:Application minWidth="955" minHeight="600"
               creationComplete="creationCompleteHandler(event)"
               xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx">

    <fx:Script>
        <![CDATA[
            import mx.core.ByteArrayAsset;
            import mx.events.FlexEvent;

            // my file is "ABC "
            // strangely enough if I remove the space at the end the string in code is empty
            [Embed(source="data/abc.txt", mimeType="application/octet-stream")]
            private var abcFile:Class;

            protected function creationCompleteHandler(event:FlexEvent):void
            {
                var abcByteArray:ByteArrayAsset = ByteArrayAsset(new abcFile());
                var abc:String = abcByteArray.readUTFBytes(abcByteArray.length);

                trace(abc); // ABC (has a space at the end)
                trace(abc == "ABC "); // true, but notice the space at the end
            }
        ]]>
    </fx:Script>
</s:Application>

我的建议是检查尾随空格，换行。还尝试在文件末尾放置某种EOF字符。
