如何從RDS DBInstance獲取標籤

Question

當我嘗試從java的RDS DBInstances獲取標籤時遇到問題。

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:

從亞馬遜RDS API參考，它看起來像上的要求ResourceName參數是必需的： http://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_ListTagsForResource.html

嘗試設置該請求的參數與RDS之一數據庫實例ID，你應該得到一個很好的迴應。

我不確定爲什麼你沒有從服務中獲得更有用的錯誤信息。我會將這些信息傳遞給RDS團隊。

希望有幫助！
