Flex：读取字节数组

发布于 2024-09-24 17:56:51 字数 1063 浏览 0 评论 0原文

我使用以下命令将文件上传到 Flex：

        private var filer:FileReference;
        protected function button1_clickHandler(event:MouseEvent):void
        {
            var fd:String = "Files (*)"; 
            var fe:String = "*"; 
            var ff:FileFilter = new FileFilter(fd, fe);
            filer = new FileReference();
            filer.addEventListener(Event.SELECT, onFileSelect);
            filer.browse(new Array(ff));
            filer.addEventListener(Event.COMPLETE, 
                function (e:Event):void {
                    e.currentTarget.data.toString();
                }
            );
        }
        private function onFileSelect(e:Event):void {
            filer.load(); 
        }

我的文件如下所示： alt text

这是原始文件： http://sesija.com/up/1.txt

我需要读取上传的文件并解析它。问题是，在我的 e.currentTarget.data.toString(); 中，我只得到 '1' 而不是字符串的其余部分。

知道如何成功读取整个 txt 文件吗？

I use the following to upload a file to Flex:

        private var filer:FileReference;
        protected function button1_clickHandler(event:MouseEvent):void
        {
            var fd:String = "Files (*)"; 
            var fe:String = "*"; 
            var ff:FileFilter = new FileFilter(fd, fe);
            filer = new FileReference();
            filer.addEventListener(Event.SELECT, onFileSelect);
            filer.browse(new Array(ff));
            filer.addEventListener(Event.COMPLETE, 
                function (e:Event):void {
                    e.currentTarget.data.toString();
                }
            );
        }
        private function onFileSelect(e:Event):void {
            filer.load(); 
        }

And my file looks like this:
alt text

Here is the original file: http://sesija.com/up/1.txt

I need to read the uploaded file and parse it. The problem is that in my e.currentTarget.data.toString(); I get only '1' and not the rest of the String.

Any idea on how to successfully read this entire txt file?

data 属性是ByteArray。不要使用 toString 方法（显然将 NULL 字节视为字符串结尾），而是使用 ByteArray 类的特定读取方法，例如 readByte、readInt > 等。

var array:Array = [];
var ba:ByteArray = e.currentTarget.data as ByteArray;
while(ba.bytesAvailable != 0){
    array.push(ba.readByte());
}
trace(array.join(", "));

您可能想阅读使用字节数组

The data property is a ByteArray. Instead of using the toString method (which apparently treats NULL byte as end of string), use specific read methods of the ByteArray class like readByte, readInt etc.

var array:Array = [];
var ba:ByteArray = e.currentTarget.data as ByteArray;
while(ba.bytesAvailable != 0){
    array.push(ba.readByte());
}
trace(array.join(", "));
