是否可以将图像从本地高清上传到远程 AMFPHP 方法？

Question

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，尽管我知道 FP10 有一个 FileReference.data 方法。

Answer 1

据我所知是这样。 您可以将 FileReference 的内容直接传递给 php 脚本。

查看编程附带的示例闪光CS3。

如果有帮助的话，这里是一些示例代码。 这不是我写的，是 Adob​​e 写的。

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;
        }
    }
