flex+php實現檔案的上傳

網上找了一個用fileRefrenceList作為檔案的選擇，貌似用這種方法不能限定上傳檔案的類型，不過經過測試，確實能啟動並執行。

為方便起見，把它封裝成了一個類，並加上了注釋，便於大家和自己以後使用。

UploadImage.as:

package exchage
{
 import flash.events.Event;
 import flash.net.FileReference;
 import flash.net.FileReferenceList;
 import flash.net.URLRequest;
 import mx.controls.Alert;
 
 public class UploadImage
 {

      private var urlRequest:URLRequest;
         private var fileReferenceList:FileReferenceList;
         private var serverSideScript:String = http://www.路徑/uploadImage.php;  //處理上傳的指令檔路徑
         
         [Bindable]
         public var statusText:String;                                                                    //記錄上傳檔案狀態
   
            public function init():void
            {
           urlRequest = new URLRequest(serverSideScript);                                      //串連上
             fileReferenceList = new FileReferenceList();
               fileReferenceList.addEventListener(Event.SELECT, fileSelectedHandler);    //設定檔案選擇監聽
            }
    
       public  function uploadFile():void
       {
             init();
             fileReferenceList.browse();                                                                    //開啟瀏覽對話方塊
       }
    
       private function fileSelectedHandler(event:Event):void                                    //檔案選擇監聽響應函數
       {
        var fileReference:FileReference;
          var fileReferenceList:FileReferenceList = FileReferenceList(event.target);
          var fileList:Array = fileReferenceList.fileList;

          fileReference = FileReference(fileList[0]);
           
          fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);  //設定上傳過程結束監聽
          fileReference.upload(urlRequest);
          
          statusText = "上傳中...";

       }
    
       private function uploadCompleteHandler(event:Event):void                               //檔案上傳完畢監聽相應函數
       {
          statusText = "上傳成功的檔案: " + event.target.name;
       }

 }
}

 

uploadImage.php
