在aws-java-sdk中复制源对象密钥无效

Question

我试图通过Scala代码将Parquet文件从一个AWS S3桶复制到另一个AWS桶中。我在复写电话上遇到了异常。下面是堆栈跟踪：

software.amazon.awssdk.services.s3.model.S3Exception: Invalid copy source object key (Service: S3, Status Code: 400, Request ID: ZDSVGXX276C1F416)

我将有效路径传递到s3桶，并将文件名传递给方法调用。那么，这个问题的原因是什么呢？

复制导致错误的文件的代码：

 def copyObjects(fromBucket: String, objectKey: String, toBucket: String): CopyObjectResponse = {
    val copyRequest = CopyObjectRequest
      .builder()
      .copySource(fromBucket)
      .destinationBucket(toBucket)
      .destinationKey(objectKey)
      .build()

    val copyResponse = awsS3Client.copyObject(copyRequest)

    val contents = copyResponse.copyObjectResult.toString
    logger.info(s"Copy response contents ${contents}")
    logger.info(s"Found ${contents.length} elements in storage with path $fromBucket")
    copyResponse
  }

该方法调用：

copyFiles("s3a://qa/snapshots/urls/date=20220822.parquet", "part-00192-4130220041757319704-c12af88d-c000.snappy.parquet", "s3a://qa/urls-final/")

Answer 1

尝试在键的开头添加一个/。
