나는 성공적으로 AWS S3에 여러 부분으로 파일을 업로드하고 있지만, 지금은 각 부분에 광고에 MD5 체크섬을하려고 해요 :AWS S3 다중 파트 업로드를위한 md5 체크섬을 생성하는 방법은 무엇입니까?
static void sendPart(existingBucketName, keyName, multipartRepsonse, partNum,
sendBuffer, partSize, vertx, partETags, s3, req, resultClosure)
{
// Create request to upload a part.
MessageDigest md = MessageDigest.getInstance("MD5")
byte[] digest = md.digest(sendBuffer.bytes)
println(digest.toString())
InputStream inputStream = new ByteArrayInputStream(sendBuffer.bytes)
UploadPartRequest uploadRequest = new UploadPartRequest()
.withBucketName(existingBucketName).withKey(keyName)
.withUploadId(multipartRepsonse.getUploadId()).withPartNumber(partNum)
.withInputStream(inputStream)
.withMD5Digest(Base64.getEncoder().encode(digest).toString())
.withPartSize(partSize);
// Upload part and add response to our list.
vertx.executeBlocking({ future ->
// Do the blocking operation in here
// Imagine this was a call to a blocking API to get the result
try {
println("Sending chunk for ${keyName}")
PartETag eTag = s3.uploadPart(uploadRequest).getPartETag()
partETags.add(eTag);
println("Etag: " + eTag.ETag)
req.response().write("Sending Chunk\n")
} catch(Exception e) {
}
def result = "success!"
future.complete(result)
}, resultClosure)
}
나는 다음과 같은 오류 얻을 그러나 :
AmazonS3Exception: The XML you provided was not well-formed or did not validate against our published schema (Service: Amazon S3; Status Code: 400; Error Code: MalformedXML; Request ID: 91542E819781FDFC), S3 Extended Request ID: yQs45H/ozn5+xlxV9lRgCQWwv6gQysT6A4ablq7/Epq06pUzy0qGvMc+YAkJjo/RsHk2dedH+pI=
을 내가 뭘 잘못하고 있니?
