Scala：如何将protobuf ByteString对象转换为字节？

Question

I have function that returns a ByteString object:

private def getEvent(value: DataOutputValue): com.google.protobuf.ByteString = {
  value.getRecordedEvent.getEvent.getEvent
}

How do I get just the bytes from this in Scala?

Answer 1

调用toByteArray ：

val bytes = getEvent(someDateOutput).toByteArray
