error-handling - swfupload处理错误

Question

我不知道这样做。我从下载包中找到的样本开始，并根据需要进行了编辑。
我在php服务器文件脚本中进行了扩展名验证，因此，如果扩展名不在白名单中，脚本将退出并显示错误。
我不知道如何获取自定义消息。

有php功能

function HandleError($message) {
    header("HTTP/1.1 500 Internal Server Error");
    echo $message;
}

但这只返回500，而不是$ message!这是js uploadError()

function uploadError(file, errorCode, message) {
try {
    var progress = new FileProgress(file, this.customSettings.progressTarget);
    progress.setError();
    progress.toggleCancel(false);

    switch (errorCode) {
    case SWFUpload.UPLOAD_ERROR.HTTP_ERROR:
        progress.setStatus("Errore upload: " + message);
        this.debug("Error Code: HTTP Error, File name: " + file.name + ", Message: " + message);
        break;
    case SWFUpload.UPLOAD_ERROR.UPLOAD_FAILED:
        progress.setStatus("Upload fallito.");
        this.debug("Error Code: Upload Failed, File name: " + file.name + ", File size: " + file.size + ", Message: " + message);
        break;
    case SWFUpload.UPLOAD_ERROR.IO_ERROR:
        progress.setStatus("Errore Server (IO)");
        this.debug("Error Code: IO Error, File name: " + file.name + ", Message: " + message);
        break;
    case SWFUpload.UPLOAD_ERROR.SECURITY_ERROR:
        progress.setStatus("Errore Security");
        this.debug("Error Code: Security Error, File name: " + file.name + ", Message: " + message);
        break;
    case SWFUpload.UPLOAD_ERROR.UPLOAD_LIMIT_EXCEEDED:
        progress.setStatus("Limite upload superato.");
        this.debug("Error Code: Upload Limit Exceeded, File name: " + file.name + ", File size: " + file.size + ", Message: " + message);
        break;
    case SWFUpload.UPLOAD_ERROR.FILE_VALIDATION_FAILED:
        progress.setStatus("File non valido.  Upload ignorato.");
        this.debug("Error Code: File Validation Failed, File name: " + file.name + ", File size: " + file.size + ", Message: " + message);
        break;
    case SWFUpload.UPLOAD_ERROR.FILE_CANCELLED:
        // If there aren't any files left (they were all cancelled) disable the cancel button
        if (this.getStats().files_queued === 0) {
            document.getElementById(this.customSettings.cancelButtonId).disabled = true;
        }
        progress.setStatus("Cancellato.");
        progress.setCancelled();
        break;
    case SWFUpload.UPLOAD_ERROR.UPLOAD_STOPPED:
        progress.setStatus("Sospeso.");
        break;
    default:
        progress.setStatus("Errore non gestito: " + errorCode);
        this.debug("Error Code: " + errorCode + ", File name: " + file.name + ", File size: " + file.size + ", Message: " + message);
        break;
    }
} catch (ex) {
    this.debug(ex);
}

如果我注释掉 header()函数，它将在进度栏中显示错误(是)，但是将其视为成功，并且不必将其视为错误。删除 header()后，将js脚本转到 uploadSuccess而不是 uploadError。
该文档真的很丑，我什么也找不到。

删除标题，然后在exit(0)之后添加echo $message。我认为这将解决问题。
