我正在 AS3 中做一个项目，用户可以在其中设计一些东西并在之后订购。设计导出为 PDF、PNG 和 XML。这些文件我想保存在服务器上。在 MAMP 上一切正常，我得到了 HTTPStatus 200，请注意，我从 MAMP 运行我的 SWF，但是在远程服务器上成功访问了 php 脚本，并且文件也成功写入了远程服务器。但是，当我将 SWF 复制到远程服务器时，文件没有保存并且我得到 HTTPStatus 0。
在我使用的类中（参见下面的 AS3 代码），我使用 URLLoader 来获取以下一行 php 脚本：
<?php file_put_contents($_POST['location'] . $_POST['fileName'], base64_decode($_POST['fileData']));
这里是 AS3 类：
public class ServerConnection extends Sprite
{
private var _files:Array = new Array();
private var _fileNames:Array;
private var _fileLocation:String = "";
private var _scriptLocation:String;
private var _fileSavesInProgress:Array = new Array();
public function ServerConnection(scriptLocation:String = null, files:Array = null, fileNames:Array = null)
{
if (scriptLocation) setScriptLocation(scriptLocation);
if (files) setFiles(files);
if (fileNames) setFileNames(fileNames);
}
public function encodeFiles():void {
for(var i:uint = 0; i < _files.length; i++) {
_files[i] = encodeFile(_files[i]);
}
}
public function encodeFile(byteArray:ByteArray):Base64Encoder {
var base64:Base64Encoder = new Base64Encoder();
base64.encodeBytes(byteArray);
return base64;
}
public function saveFiles(location:String = null):void {
if (location) setFileLocation(location);
for(var i:uint = 0; i < _files.length; i++) {
_files[i] = saveFile(_files[i], _fileNames[i]);
}
}
public function saveFile(encodedFile:Base64Encoder, fileName:String = "test"):void {
var data:URLVariables = new URLVariables();
data.fileData = encodedFile;
data.fileName = fileName;
data.location = _fileLocation;
this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: a save file request was made for " +
fileName + "\n" +
"url: " + _fileLocation + "\n" +
" scriptLocation: " + _scriptLocation + "\n"
));
var request:URLRequest = new URLRequest(_scriptLocation);
request.method = URLRequestMethod.POST;
request.data = data;
var loader:URLLoader= new URLLoader();
loader.addEventListener(Event.COMPLETE, function(e:Event):void {fileSaved(loader);});
loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatus);
loader.addEventListener(IOErrorEvent.IO_ERROR, ioError);
_fileSavesInProgress.push(loader);
try {
loader.load(request);
} catch (e:*) {
this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: error:* = " + e + " \n"));
}
//navigateToURL(request);
}
public function displayObjectToPNG(displayObject:*, scale:Number = 1):ByteArray {
var bmpData:BitmapData=new BitmapData(displayObject.width, displayObject.height, true, 0xFFFFFF);
bmpData.draw(displayObject);
var byteArray:ByteArray = PNGEncoder.encode(bmpData);
return byteArray;
}
public function xmlToByteArray(xml:XML):ByteArray {
var byteArray:ByteArray = new ByteArray();
byteArray.writeUTFBytes(xml);
return byteArray;
}
public function setScriptLocation(url:String):void {
_scriptLocation = url;
}
public function setFileLocation(url:String):void {
_fileLocation = url;
}
public function setFiles(array:Array, encode:Boolean = true):void {
for each(var file:* in array) {
for each(var type:XML in describeType(file).extendsClass.@type) {
if (type == "flash.display::DisplayObject") file = displayObjectToPNG(file);
}
if (typeof(file) == "xml") {
file = xmlToByteArray(file);
}
_files.push(file);
}
if (encode) encodeFiles();
}
public function setFileNames(array:Array):void {
_fileNames = array;
}
// EVENTS
private function httpStatus(e:HTTPStatusEvent):void {
this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: status = " + e.status + " \n"));
}
private function ioError(e:IOErrorEvent):void {
this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: IOErrorID = " + e.errorID + " Message: "+ e.text + " \n"));
}
private function fileSaved(loader:URLLoader):void {
this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: file save completed. " + (_fileSavesInProgress.length -1) + " files to go \n"));
_fileSavesInProgress.splice(_fileSavesInProgress.indexOf(loader), 1);
if (_fileSavesInProgress.length == 0) {
filesSaved();
}
}
private function filesSaved():void {
this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: files saved \n"));
this.dispatchEvent (new ClassAttributesLoaded(ClassAttributesLoaded.CLASS_ATTRIBUTES_LOADED));
}
}
我这样实现
var s:ServerConnection = new ServerConnection(
CONSTANT.SAVE_FILE_SCRIPT_LOCATION,
[currentTemplate.getXML(), exampleTemplate, pdf.save(Method.LOCAL)],
[CONSTANT.PACKAGE_ID + ".xml", CONSTANT.PACKAGE_ID + ".png", CONSTANT.PACKAGE_ID + ".pdf"]
);
s.addEventListener(DebugEvent.MESSAGE, writeToDebug);
s.addEventListener(ClassAttributesLoaded.CLASS_ATTRIBUTES_LOADED, exit);
s.saveFiles(CONSTANT.RELATIVE_FILE_DIRECTORY);
当我更改 loader.load(request); 导航到URL（请求）；代码确实有效。在本地和远程服务器上。出于明显的原因，在这种情况下我不能使用 navigateToURL。我确实认为 navigateToURL 确实有效并且 loader.load(request) 并没有说明问题的事实......但是什么？
我有点坚持这一点，并希望得到帮助。提前致谢！
PS：为了测试，我已将远程 DIR 的权限设置为 777。此外，文件已成功从 MAMP 保存到远程，如前所述。
