无法写入S3

Question

I am trying to write a file to Amazon S3.

val creds = new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY)
val amazonS3Client = new AmazonS3Client(creds)
val filePath = "/service2/2019/06/30/21"
val fileContent = "{\"key\":\"value\"}"
val meta = new ObjectMetadata();
amazonS3Client.putObject(bucketName, filePath, new ByteArrayInputStream(fileContent.getBytes), meta)

The program is finished with no error, but no file is written into the bucket.

Answer 1

The key argument seems to have a typo. Try without the initial forward slash

val filePath = "service2/2019/06/30/21"

instead of

val filePath = "/service2/2019/06/30/21"
