java - 使用原始字节而不是文件的AWS S3分段上传

Question

我正在尝试创建分段上传，但是我收到原始数据，而不是文件，并且在文档中的示例中，分段请求需要文件，而不是数据，例如

UploadPartRequest uploadRequest = new UploadPartRequest()
        .withBucketName(bucketName)
        .withKey(key)
        .withUploadId(initResponse.getUploadId())
        .withPartNumber(part) // parts start with 1
        .withFileOffset(filePosition)
        .withFile(filePath.toFile())
        .withPartSize(partSize);
UploadPartResult uploadPartResult = amazonS3.uploadPart(uploadRequest);
partETags.add(uploadPartResult.getPartETag());

有什么方法可以将原始再见放入 UploadPartRquest 中吗？类似的东西

byte[] data = getData();
UploadPartRequest uploadRequest = new UploadPartRequest()
        .withBucketName(bucketName)
        .withKey(key)
        .withUploadId(initResponse.getUploadId())
        .withPartNumber(part) // parts start with 1
        .withFileOffset(filePosition)
        .withData(data)
        .withPartSize(partSize);
UploadPartResult uploadPartResult = amazonS3.uploadPart(uploadRequest);
partETags.add(uploadPartResult.getPartETag());

或者我是否坚持创建临时文件，将其发送到请求对象，然后删除所述文件？

感谢您的帮助!

看起来有 a withInputStream method并且您始终可以通过 ByteArrayInputStream 从字节数组创建 InputStream 。结合起来，我认为这会做你想要的。
