我正在尝试使用 Akka HTTP 和 Alpakka S3 连接器将一个大文件（目前为 90 MB）上传到 S3。它对于小文件（25 MB）工作正常，但是当我尝试上传大文件（90 MB）时，出现以下错误：

尽管我最后收到成功消息，但文件未完全上传。它只能上传 45-50 MB。
我正在使用以下代码： S3Utility.scala
class S3Utility(implicit as: ActorSystem, m: Materializer) {
private val bucketName = "test"
def sink(fileInfo: FileInfo): Sink[ByteString, Future[MultipartUploadResult]] = {
val fileName = fileInfo.fileName
S3.multipartUpload(bucketName, fileName)
}
}
路线：
def uploadLargeFile: Route =
post {
path("import" / "file") {
extractMaterializer { implicit materializer =>
withoutSizeLimit {
fileUpload("file") {
case (metadata, byteSource) =>
logger.info(s"Request received to import large file: ${metadata.fileName}")
val uploadFuture = byteSource.runWith(s3Utility.sink(metadata))
onComplete(uploadFuture) {
case Success(result) =>
logger.info(s"Successfully uploaded file")
complete(StatusCodes.OK)
case Failure(ex) =>
println(ex, "Error in uploading file")
complete(StatusCodes.FailedDependency, ex.getMessage)
}
}
}
}
}
}
任何帮助将不胜感激。谢谢
您可以将文件分成更小的块并重试吗，这里是示例代码：
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
.withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("some-kind-of-endpoint"))
.withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials("user", "pass")))
.disableChunkedEncoding()
.withPathStyleAccessEnabled(true)
.build();
// Create a list of UploadPartResponse objects. You get one of these
// for each part upload.
List<PartETag> partETags = new ArrayList<PartETag>();
// Step 1: Initialize.
InitiateMultipartUploadRequest initRequest = new
InitiateMultipartUploadRequest("bucket", "key");
InitiateMultipartUploadResult initResponse =
s3Client.initiateMultipartUpload(initRequest);
File file = new File("filepath");
long contentLength = file.length();
long partSize = 5242880; // Set part size to 5 MB.
try {
// Step 2: Upload parts.
long filePosition = 0;
for (int i = 1; filePosition < contentLength; i++) {
// Last part can be less than 5 MB. Adjust part size.
partSize = Math.min(partSize, (contentLength - filePosition));
// Create a request to upload a part.
UploadPartRequest uploadRequest = new UploadPartRequest()
.withBucketName("bucket").withKey("key")
.withUploadId(initResponse.getUploadId()).withPartNumber(i)
.withFileOffset(filePosition)
.withFile(file)
.withPartSize(partSize);
// Upload part and add response to our list.
partETags.add(
s3Client.uploadPart(uploadRequest).getPartETag());
filePosition += partSize;
}
// Step 3: Complete.
CompleteMultipartUploadRequest compRequest = new
CompleteMultipartUploadRequest(
"bucket",
"key",
initResponse.getUploadId(),
partETags);
s3Client.completeMultipartUpload(compRequest);
} catch (Exception e) {
s3Client.abortMultipartUpload(new AbortMultipartUploadRequest(
"bucket", "key", initResponse.getUploadId()));
}
增加Akka HTTP服务器的
idle-timeoutinfiniteakka.http.server.idle-timeout=infinite
这会增加服务器预计空闲的时间段。默认情况下，其值为 60 秒。如果服务器无法在该时间段内上传文件，它将关闭连接并抛出“多部分实体意外结束”错误。
我在使用多部分上传时遇到新的异常。 将文件上传到 s3 时发生错误。异常中止： org.bouncycastle.crypto.io.InvalidCipherTextIOException：完成密码时出错 导致：org.bouncycastle.crypto.InvalidCipherTextException：GCM 中的 mac 检查失败
