任何AMFPHP专家都可以告诉我是否可以使用FileReference
将我从本地HD选择的文件上传到AMFPHP方法?
我必须以FP9为目标,但我知道FP10有FileReference.data
方法。
答案 0 :(得分:0)
据我所知。您可以将FileReference的内容直接传递给php脚本。
查看编程Flash CS3附带的samples。
以下是一些示例代码,如果有帮助的话。我没有写这个,Adobe做了。
package com.example.programmingas3.fileio {
import flash.events.*;
import flash.net.FileReference;
import flash.net.URLRequest;
import fl.controls.Button;
import fl.controls.ProgressBar;
public class FileUpload {
// Hard-code the URL of the remote upload script.
private const UPLOAD_URL:String = "http://www.yourdomain.com/upload_script.cfm";
private var fr:FileReference;
// Define reference to the upload ProgressBar component.
private var pb:ProgressBar;
// Define reference to the "Cancel" button which will immediately stop the upload in progress.
private var btn:Button;
public function FileUpload() {
}
/**
* Set references to the components, and add listeners for the SELECT,
* OPEN, PROGRESS, and COMPLETE events.
*/
public function init(pb:ProgressBar, btn:Button):void {
// Set up the references to the progress bar and cancel button, which are passed from the calling script.
this.pb = pb;
this.btn = btn;
fr = new FileReference();
fr.addEventListener(Event.SELECT, selectHandler);
fr.addEventListener(Event.OPEN, openHandler);
fr.addEventListener(ProgressEvent.PROGRESS, progressHandler);
fr.addEventListener(Event.COMPLETE, completeHandler);
}
/**
* Immediately cancel the upload in progress and disable the cancel button.
*/
public function cancelUpload(e:MouseEvent):void {
fr.cancel();
// pb.label = "UPLOAD CANCELLED";
btn.enabled = false;
}
/**
* Launch the browse dialog box which allows the user to select a file to upload to the server.
*/
public function startUpload(e:MouseEvent):void {
fr.browse();
}
/**
* Begin uploading the file specified in the UPLOAD_URL constant.
*/
private function selectHandler(event:Event):void {
var request:URLRequest = new URLRequest();
request.url = UPLOAD_URL;
fr.upload(request);
}
/**
* When the OPEN event has dispatched, change the progress bar's label
* and enable the "Cancel" button, which allows the user to abort the
* upload operation.
*/
private function openHandler(event:Event):void {
// pb.label = "UPLOADING";
btn.enabled = true;
}
/**
* While the file is uploading, update the progress bar's status and label.
*/
private function progressHandler(event:ProgressEvent):void {
// pb.label = "UPLOADING %3%%";
pb.setProgress(event.bytesLoaded, event.bytesTotal);
}
/**
* Once the upload has completed, change the progress bar's label and
* disable the "Cancel" button since the upload is already completed.
*/
private function completeHandler(event:Event):void {
// pb.label = "UPLOADING COMPLETE";
pb.setProgress(0, 100);
btn.enabled = false;
}
}
}
