出现"content-MD5"错误.在AWS s3存储桶上 [英] Error with "content-MD5" on AWS s3 bucket

问题描述

我正在创建一个应用程序，该应用程序将视频文件发送到Amazon s3存储桶，但只能发送1个视频，然后必须将apk重新上传到手机.引发的错误与服务上的"BadDigest"错误有关:"Amazon S3".以下是输出错误.

I am creating an application that sends a video file to an Amazon s3 bucket but can only send 1 video before having to re-upload the apk to the phone. The error being thrown has something to do with a "BadDigest" error on the service: "Amazon S3". Below is the output error.

如果您需要更多信息，请告诉我，这是一个时间敏感的问题.

Please let me know if you need further information, this is a fairly time sensitive question.

编辑1 作为对donkon的响应，这是我用来将文件发送到服务器的代码:

EDIT 1 In response to donkon, here is the code that I am using to send my files to the server:

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);
    }
}

推荐答案

问题是内容在上载时正在更改.尝试使用您的代码上传静态文件(即已完成录制的视频)，它应该可以正常工作.

The issue is that the content is changing as you are uploading it. Try using your code to upload a static file (I.e. a video that is done recording) and it should work.
