独立运行时，为什么不IOErrorEvents包含的网址是什么？ [英] Why don't IOErrorEvents contain the URL when running standalone?

问题描述

下面是一个 <一个简单的例子code>的URLLoader 。

Here is a simple example of an URLLoader.

var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("http://example.com/doesntexist.txt");
loader.addEventListener(IOErrorEvent.IO_ERROR, function(e:IOErrorEvent){
    textbox.text = e.toString(); // Text box on stage
});
loader.load(request);

此行​​为古怪。

从Flash或调试从闪存中运行时，该错误看起来是这样的。

When running from Flash or debugging from Flash, the error looks like this.

[IOErrorEvent TYPE =ioError在泡沫=假可取消=假的EventPhase = 2文本=错误＃2032：流错误网址：的 http://example.com/doesntexist.txt ]

[IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://example.com/doesntexist.txt"]

不过，由于运行时瑞士法郎或的.exe 投影机，它看起来像这样。

But, when running as a .swf or an .exe projector, it looks like this.

[IOErrorEvent TYPE =ioError在泡沫=假可取消=假的EventPhase = 2文本=错误＃2032]

[IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]

为什么会这样呢？有没有一种方式来获得的第一个结果，当独立的？

Why is this so? Is there a way to get the first result when standalone?

编辑：我需要得到它的工作作为一个投影机

I need to get it working as a projector.

推荐答案

虽然我不能确定为什么（可能是背后的Flash Player中的场景效率的事情），这里是一个办法来完成你想什么

While I'm not sure about the why (probably an efficiency thing behind the scenes in flash player), here is a way to accomplish what you'd like:

您可以编写扩展的自定义类的URLLoader 的存储网址给你。

You can write a custom class that extends URLLoader that stores the url for you.

package 
{
    import flash.net.URLLoader;
    import flash.net.URLRequest;

    public class MyURLLoader extends URLLoader
    {
        public var request:URLRequest; //all were doing here is adding this public property and setting it when loading into the URLLoader

        public function MyURLLoader(request_:URLRequest) {
            request = request_;
            super(request);
        }

        override public function load(request_:URLRequest):void 
        {
            request = request_;
            super.load(request);
        }
    }
}

然后处理你的错误的时候，你可以参考的网址，像这样：

Then when handling your error, you can reference the URL like so:

var loader:MyURLLoader = new MyURLLoader();
var request:URLRequest = new URLRequest("http://example.com/doesntexist.txt");

loader.addEventListener(IOErrorEvent.IO_ERROR, function(e:IOErrorEvent){
    textbox.text = e.toString() + " URL: " + MyURLLoader(e.currentTarget).request; // Text box on stage
});
loader.load(request);
