Question

我正在尝试上传文件。使用
flash.filesystem.File
但是应用程序一直在崩溃

private function uploadFile(f:File):void
{
f.addEventListener(ProgressEvent.PROGRESS, uploadProgress);
f.addEventListener(Event.COMPLETE, callBackFunc);
f.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA , callBackFunc);
f.addEventListener(SecurityErrorEvent.SECURITY_ERROR, uploadError);
f.addEventListener(HTTPStatusEvent.HTTP_STATUS, uploadError);   
f.addEventListener(IOErrorEvent.IO_ERROR, uploadError);
f.upload(urlRequest,"Filedata",false);
}

Answer 1

我认为您收到undefined错误或null reference错误？这是因为你传递file作为参数，然后访问函数中的f。

private function uploadFile(file:File):void
{
    file.addEventListener(ProgressEvent.PROGRESS, uploadProgress);
    file.addEventListener(Event.COMPLETE, callBackFunc);
    file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA , callBackFunc);
    file.addEventListener(SecurityErrorEvent.SECURITY_ERROR, uploadError);
    file.addEventListener(HTTPStatusEvent.HTTP_STATUS, uploadError);   
    file.addEventListener(IOErrorEvent.IO_ERROR, uploadError);
    file.upload(urlRequest,"Filedata",false);
}
