[英]uploading files to server using AS3 and PHP error
我正在嘗試使用AS3和PHP將文件上傳到服務器。 這是我的AS3代碼,然后是PHP代碼。 我嘗試上傳到的文件夾可寫。 文件大小約為20Kb。 php腳本在我的服務器上,並且flash文件將其調用。
var UPLOAD_URL: String ="linktophpscriptonMysite"
var fr: FileReference;
var request: URLRequest = new URLRequest();
request.url = UPLOAD_URL;
function startThis(): void {
fr = new FileReference();
fr.addEventListener(Event.SELECT, selectHandler);
fr.addEventListener(Event.OPEN, openHandler);
fr.addEventListener(ProgressEvent.PROGRESS, progressHandler);
fr.addEventListener(Event.COMPLETE, completeHandler);
fr.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
startUpload()
}
function startUpload(): void {
try {
var success: Boolean = fr.browse();
trace("success")
} catch (error: Error) {
trace("Unable to browse for files.", Error);
}
}
function progressHandler(event: ProgressEvent): void {
trace(event.bytesLoaded, event.bytesTotal);
}
function ioErrorHandler(event: IOErrorEvent): void {
//trace("Some error ", event.target.data.systemResult);
//systemResult is echoed by PHP
}
function openHandler(event: Event): void {
try {
//var success: Boolean = fr.browse();
} catch (error: Error) {
trace("Unable to browse for files.", Error);
}
}
function completeHandler(event: Event): void {
trace(event.target.data.systemResult);
//this reads the result, again, from PHP echo "systemResult=all is good";
}
function selectHandler(event: Event): void {
fr.upload(request);
}
然后,這是php代碼:此代碼是我在php手冊網站上找到的常規上傳腳本
<?php
header('Content-Type: text/plain; charset=utf-8');
try {
// Undefined | Multiple Files | $_FILES Corruption Attack
// If this request falls under any of them, treat it invalid.
if (
!isset($_FILES['upfile']['error']) ||
is_array($_FILES['upfile']['error'])
) {
echo "systemResult=Error";
throw new RuntimeException('Invalid parameters.');
}
// Check $_FILES['upfile']['error'] value.
switch ($_FILES['upfile']['error']) {
case UPLOAD_ERR_OK:
break;
case UPLOAD_ERR_NO_FILE:
throw new RuntimeException('No file sent.');
case UPLOAD_ERR_INI_SIZE:
case UPLOAD_ERR_FORM_SIZE:
throw new RuntimeException('Exceeded filesize limit.');
default:
throw new RuntimeException('Unknown errors.');
}
// You should also check filesize here. max is 100 mb
if ($_FILES['upfile']['size'] > 10000000) {
throw new RuntimeException('Exceeded filesize limit.');
}
// DO NOT TRUST $_FILES['upfile']['mime'] VALUE !!
// Check MIME Type by yourself.
$finfo = new finfo(FILEINFO_MIME_TYPE);
if (false === $ext = array_search(
$finfo->file($_FILES['upfile']['tmp_name']),
array(
'jpg' => 'image/jpeg',
'png' => 'image/png',
'gif' => 'image/gif',
),
true
)) {
throw new RuntimeException('Invalid file format.');
}
// You should name it uniquely.
// DO NOT USE $_FILES['upfile']['name'] WITHOUT ANY VALIDATION !!
// On this example, obtain safe unique name from its binary data.
if (!move_uploaded_file(
$_FILES['upfile']['tmp_name'],
sprintf('./uploads/%s.%s',
sha1_file($_FILES['upfile']['tmp_name']),
$ext
)
)) {
throw new RuntimeException('Failed to move uploaded file.');
}
echo 'File is uploaded successfully.';
} catch (RuntimeException $e) {
echo $e->getMessage();
}
?>
我遇到的問題是該文件未上傳,並且為什么我沒有從php得到任何反饋。
感謝您的任何幫助
更新:謝謝@akmozo的答復和回答。 就像我在評論中說的那樣,此腳本有效
<?php
$uploads_dir = './uploads/';
if( $_FILES['Filedata']['error'] == 0 ){
if( move_uploaded_file( $_FILES['Filedata']['tmp_name'], $uploads_dir.$_FILES['Filedata']['name'] ) ){
echo 'ok';
echo 'systemResult=Awesome';
exit();
}
}
echo 'error';
echo 'systemResult=did not work';
exit();
?>
默認情況下, FileReference
對象的上載數據字段名稱為"Filedata"
,這就是您應該在PHP代碼中使用的名稱( $_FILES['Filedata']
...)。
您當然可以在FileReference.upload()
函數中更改該名稱:
fr.upload(request, 'upfile');
希望能有所幫助
