使用FileReference类+PHP上传文件

2016-8-29 zhulinan Flash

舞台上放一个按钮和一个显示上传进度的实例，运行界面如下：

as代码：
package { import flash.display.MovieClip; import flash.events.*; import flash.net.FileReference; import flash.net.URLRequest; public class Main extends MovieClip { private var uploadURL:URLRequest; private var file:FileReference; public function Main() { addEventListener(Event.ADDED_TO_STAGE, addedHandle); } private function addedHandle(e:Event):void { prgBar.visible = false; prgBar.gotoAndStop(1); btnA.addEventListener(MouseEvent.CLICK, btnAClickHandle); } private function btnAClickHandle(e:MouseEvent):void { uploadURL = new URLRequest(); uploadURL.url = "http://www.yourwebsite.com/upload.php"; file = new FileReference(); file.addEventListener(Event.SELECT, selectHandle); file.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandle); file.addEventListener(ProgressEvent.PROGRESS, progressHandle); file.addEventListener(Event.COMPLETE, completeHandle); file.browse(); } private function selectHandle(event:Event):void { var file:FileReference = FileReference(event.target); file.upload(uploadURL); prgBar.visible = true; prgBar.gotoAndStop(1); } private function ioErrorHandle(event:IOErrorEvent):void { trace("ioErrorHandler: " + event); } private function progressHandle(event:ProgressEvent):void { var file:FileReference = FileReference(event.target); var kbs:int = Math.floor(event.bytesTotal / 1024); var frm:int = Math.floor(event.bytesLoaded * 100 / event.bytesTotal); prgBar.txtStatus.text = "文件共" + kbs + "KB，已完成" + frm + "%"; prgBar.gotoAndStop(frm); } private function completeHandle(event:Event):void { prgBar.gotoAndStop(prgBar.totalFrames); prgBar.txtStatus.text = "文件上传完毕！"; } } }

php代码：
<?php if ($_FILES ["Filedata"] ["error"] > 0) { exit("Error: " . $_FILES ["Filedata"]["error"]); } $fileName = iconv("utf-8","gb2312", $_FILES ["Filedata"]["name"]); $reallyName = $fileName; if (file_exists ($reallyName)) { unlink($reallyName); } move_uploaded_file( $_FILES ["Filedata"]["tmp_name"], $reallyName); ?>
