如何檢索通過ActionScript

Question

文件上傳後JSON結果我知道了如何使用動作腳本

見upload a zip file using HTTP POST via actionscript 3.0的詳細信息上傳的文件。

代碼複製在這裏：

var urlRequest:URLRequest = new URLRequest(PUBLISH_ZIP_FILE_URL); 
// set to method=POST 
urlRequest.method = URLRequestMethod.POST; 

var params:URLVariables = new URLVariables(); 

params['data[File][title]'] = 'Title1'; 
params['data[File][description]'] = 'desc'; 

// this is where we include those non file params and data 
urlRequest.data = params; 


// now we upload the file 
// this is how we set the form field expected for the file upload 
file.upload(urlRequest, "data[File][filename]"); 

的Web應用程序負責受理文件上傳將返回包含詳細信息，如文件大小，身份證號碼等

如何訪問此JSON字符串JSON結果字符串在我的動作？

從FileReference docs，你需要一個處理程序添加到您的FileReference實例爲uploadCompleteData事件：

import flash.events.*; 

// now we upload the file 
// this is how we set the form field expected for the file upload 
file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, uploadCompleteDataHandler); 
file.upload(urlRequest, "data[File][filename]"); 

private function uploadCompleteDataHandler(event:DataEvent):void 
{ 
    trace("uploadCompleteData data: " + event.data); 
}
