Question

我正在创建一个应用程序，它将视频文件发送到亚马逊s3存储桶，但只能在将apk重新上传到手机之前发送1个视频。抛出的错误与服务上的“BadDigest”错误有关：“Amazon S3”。以下是输出错误。

如果您需要进一步的信息，请告诉我，这是一个相当时间敏感的问题。

public void submitVideoToS3Bucket(){
    TransferUtility transferUtility = new TransferUtility(s3, getApplicationContext());

    File directory = new File(getFilesDir(), "Reflex");
    final File CameraFile = new File(directory, "camera-temp.mp4");

    Date now = new Date();
    String videoName = now.toString().concat(".mp4").replace(" ", "_").replace(":", "");

    TransferObserver observer = transferUtility.upload(Constants.BUCKET_NAME, videoName, CameraFile);

    observer.setTransferListener(new TransferListener() {

        @Override
        public void onStateChanged(int id, TransferState state) {
            if (TransferState.COMPLETED == state) {
            }
            System.out.println("state change");
        }

        @Override
        public void onProgressChanged(
                int id, long bytesCurrent, long bytesTotal) {
        }

        @Override
        public void onError(int id, Exception ex) {
            ex.printStackTrace();
        }
    });
    if (TransferState.COMPLETED == observer.getState()) {
        // Handle a completed upload.
        Intent cameraIntent = new Intent(this, CameraActivity.class);
        startActivity(cameraIntent);
    }
}

问题是内容在上传时会发生变化。尝试使用您的代码上传静态文件（即完成录制的视频），它应该可以工作。
