如何从RDS DBInstance获取标签

Question

当我尝试从java的RDS DBInstances获取标签时遇到问题。

AmazonRDS rds = new AmazonRDSClient(credentialsProvider); 
ListTagsForResourceRequest request = new ListTagsForResourceRequest(); 
ListTagsForResourceResult resultedTags = rds.listTagsForResource(request); 

Status Code: 500, AWS Service: AmazonRDS, AWS Request ID: ..., AWS Error Code: InternalFailure, AWS Error Message: An internal error has occurred. Please try your query again at a later time. 
Stack Trace:

从亚马逊RDS API参考，它看起来像上的要求ResourceName参数是必需的： http://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_ListTagsForResource.html

尝试设置该请求的参数与RDS之一数据库实例ID，你应该得到一个很好的回应。

我不确定为什么你没有从服务中获得更有用的错误信息。我会将这些信息传递给RDS团队。

希望有帮助！
