使用Adobe AIR获取外部IP

Question

我们可以使用Java，C＃或VB.NET获取外部IP from this service。但我想用Adobe AIR做到这一点。如何向该链接发出请求并获取其字符串？

会是这样的：

private function makeRequest():void
{
    var loader:URLLoader = new URLLoader();

    configureListeners(loader);
    var req:URLRequest=new URLRequest("http://www.whatismyip.com/automation/n09230945.asp");

    try

    {   
        var header:URLRequestHeader=new URLRequestHeader("content-type", "text/plain");

        var header2:URLRequestHeader = new URLRequestHeader("pragma", "no-cache");

        req.requestHeaders.push(header);
        req.requestHeaders.push(header2);

        req.method = URLRequestMethod.POST;
        loader.dataFormat = URLLoaderDataFormat.TEXT;
        loader.load(req);
    }
    catch (error:Error)
    {
        trace("Unable to load requested document.");
    }
}

private function configureListeners(dispatcher:IEventDispatcher):void
{
    dispatcher.addEventListener(Event.COMPLETE, completeHandler);
}

private function completeHandler(event:Event):void
{
    var loader:URLLoader = URLLoader(event.target);
    mx.controls.Alert.show("" + loader.data);
}
