Question

我正在尝试创建一个多图像上传器（想想Coppermine），用户点击SWF中的按钮，选择一个或多个文件，然后将这些文件上传到目录。

我有一个处理上传文件的PHP脚本，我的Flash文件遍历FileReferenceList中的文件并将文件发送到此PHP脚本进行上传。 PHP脚本中的目录路径是正确的，权限设置为777。

我的ActionScript 3.0类的内容如下所示：

package com.yourfightsite.imageupload {

    import flash.display.MovieClip;
    import flash.events.Event;
    import flash.events.IOErrorEvent;
    import flash.events.MouseEvent;
    import flash.events.ProgressEvent;
    import flash.external.ExternalInterface;
    import flash.net.FileFilter;
    import flash.net.FileReference;
    import flash.net.FileReferenceList;
    import flash.net.URLRequest;

    public class ImageUpload extends MovieClip {

        private var uploadURL:URLRequest;
        private var fileRef:FileReferenceList;

        public function ImageUpload():void {
            uploadURL = new URLRequest();
            uploadURL.url = stage.loaderInfo.parameters.uploadUrl;

            fileRef = new FileReferenceList();

            uploadButton.addEventListener(MouseEvent.CLICK, buttonClickHandler);
        }

        private function buttonClickHandler(e:MouseEvent):void {
            var imageFilter:FileFilter = new FileFilter('Images', '*.jpg');
            fileRef.browse(new Array(imageFilter));
            fileRef.addEventListener(Event.SELECT, fileSelectHandler);
        }

        private function fileSelectHandler(e:Event):void {
            for each(var fileToUpload:FileReference in fileRef.fileList) {
                addFileToQueue(fileToUpload.name);
                uploadSingleFile(fileToUpload);
            }
        }

        private function uploadSingleFile(file:FileReference):void {
            file.upload(uploadURL);
            file.addEventListener(Event.COMPLETE, completeHandler);
        }

        private function ioErrorHandler(e:IOErrorEvent):void {
            trace('ioErrorHandler: ' + e);
            ExternalInterface.call('console.error', e);
        }

        private function progressHandler(e:ProgressEvent):void {
            var fileRef:FileReference = FileReference(e.target);
            var percentUploaded:Number = Math.round((e.bytesLoaded/e.bytesTotal)*100);
            updateFileInQueue(e.target.name, percentUploaded);
        }

        private function completeHandler(e:Event):void {
            markFileInQueueAsComplete(e.target.name);
        }

        private function addFileToQueue(filename:String):void {
            ExternalInterface.call('addFileToQueue', filename);
        }

        private function updateFileInQueue(filename:String, percent:Number):void {
            ExternalInterface.call('updateFileInQueue', filename, percent);
        }

        private function markFileInQueueAsComplete(filename:String):void {
            ExternalInterface.call('markFileInQueueAsComplete', filename);
        }
    }
}

类底部的三个方法在我的HTML页面中激活JavaScript函数，将文件名添加到文件队列小部件，并更新它们旁边的百分比值，最后将它们标记为完成。

但是，当我选择文件时，它们会按预期添加到文件队列小部件中，然后什么都没有。文件不会上传，文件队列小部件中的文件不会更新，也不会在发布我的电影时在控制台（我使用的是Chrome）或Flash中引发错误。

任何人都可以在上面的ActionScript中看到任何错误吗？

不确定这些是否是错误，但这里有一些想法：

是否可以找出fileRef.browse()是否使用与上传的file对象相同的对象？

在开始上传之前添加事件监听器：

private function uploadSingleFile(file:FileReference):void {
    file.addEventListener(Event.COMPLETE, completeHandler);
    file.upload(uploadURL);
}

这是上传单张照片的一些动作 - 根据您的需求进行调整。 PHP遵循。

private function onUploadCompleteData ( event : DataEvent ) : void
{
    var resultXML : XML = new XML( event.data );
    if ( resultXML == null ) return;

    var storednameString : String = resultXML..filename[0];


}               

private function uploadPicture() : void
{
    uploadFileReference = new FileReference();
    uploadFileReference.addEventListener( Event.SELECT, onSelectFile, false, 0, true  );
    uploadFileReference.addEventListener( DataEvent.UPLOAD_COMPLETE_DATA, onUploadCompleteData, false, 0, true  );
    uploadFileReference.addEventListener( IOErrorEvent.IO_ERROR, onUploadError, false, 0, true  );

    uploadFileReference.browse();

}

private function onUploadError( event : IOErrorEvent ) : void
{
     Alert.show( "Unable to upload picture.", "Photo" );
}       

private function onSelectFile( event : Event ) : void
{
    try
    {
        // this is where you pass stuff to PHP - file info, storage info
        var urlParams : URLVariables = new URLVariables();
        urlParams.some_info = some_info;
        urlParams.sessionId = phpsessionId;


        uploadURL = new URLRequest();

        // this is where you'd put the URL for your server
        uploadURL.url = serverpathString + "/php/uploadPhoto.php";

        uploadURL.method = URLRequestMethod.POST;
        uploadURL.data = urlParams;

        uploadFileReference.upload( uploadURL );
    }
    catch ( error : Error )
{
        Alert.show( "Unable to upload file.", "Photo" );
    }               
}           


<mx:Form height="100%">     
     <mx:Button label="Select" click="uploadPicture()"/>        
</mx:Form>

PHP上传文件：

<?php

  // there is a bug in the flex upload code where the session id isn't being sent. This is a patch for that.
  session_id( $_REQUEST[ 'sessionId' ] );
  $some_info = $_REQUEST[ 'some_info' ] );

  session_start();

  $maxSize = 1024 * 1000; // 1 Mb
  if ( $_FILES[ 'Filedata' ][ 'size' ] > $maxSize )
  {
          echo "<ret/>";
            return;
  }

  $filename_inbound = $_FILES[ 'Filedata' ][ 'tmp_name' ];

  $utc = microtime( true );

  move_uploaded_file( $filename_inbound, "/data/pictures/$filename" );

  // if you change the stored filename - here is where it gets returned to actionscript
  // return success / fail the same way
  echo "<ret><filename>$filename</filename></ret>";
?>
