        }

         protected function  getFormModuleDataResult_resultHandler(event:ResultEvent):void
        {
            var pathToFile:String;
            pathToFile=create003Result.lastResult; // this is path to created file
          // here i need some code from you
         }



         <nhealthreports:NhealthReports id="nhealthReports"

        <s:CallResponder id="create003Result" result="getFormModuleDataResult_resultHandler(event)"/>

推荐答案

所以你需要先将文件下载到用户的机器上，然后打开它.应该这样做(从我的项目中复制粘贴的内容，因此您可能需要稍微调整一下).

So you'd need to first download the file to the user's machine and then open it. Something like this should do it (copy pasted stuff from my projects so you might need to adjust it a bit).

此外，您的服务器可能需要一个跨域文件，以便您的应用可以从中加载文件.

Also your server might need a crossdomain file so your app can load files from it.

    private function getFormModuleDataResult_resultHandler(event:ResultEvent):void
    {
        // load file
        var loader:URLLoader = new URLLoader();
        loader.addEventListener(Event.COMPLETE, onLoadingComplete);
        loader.dataFormat = URLLoaderDataFormat.BINARY;
        loader.load(new URLRequest(pathToFile));
    }

    private function onLoadingComplete(event:Event):void
    {
        // get the data as bytearray
        var data:ByteArray = event.target.data;

        // you will probably need to figure this out from your server path or define your own here
        var fileName:String = "MyFilename.doc";

        // create a file under the application storage directory (C:\Users\YOURUSERHERE\AppData\Roaming\RateBook\Local Store)
        // you can store the file anywhere but it is recommended to do it here 
        // as users with restricted access on their machines (non-admin users) might have trouble saving the files elsewhere
        var file:File = File.applicationStorageDirectory.resolvePath(fileName);

        //create a file stream to be able to write the content of the file    
        var fileStream:FileStream = new FileStream();
        //open the file stream and set for Write
        fileStream.open(file, FileMode.WRITE);
        //writes the bytes
        fileStream.writeBytes(data, 0, data.length);
        //close the stream
        fileStream.close();

        // by now the file should be saved to disk, let's open it
        // Naturally this assumes that the user have the file extension (like .doc) associated with the correct program (MS Word)
        file.openWithDefaultApplication();
    }
