Question

我正在使用以下代码删除 Test1 和 Test2 集合，但是我收到了FailedRequestException。请指导我解决此问题。

仅当有多个收藏夹时，我才会遇到此问题。

QueryManager queryManager = client.newQueryManager();
DeleteQueryDefinition queryDefinition = queryManager.newDeleteDefinition();
String[] collections = {"Test1", "Test2"};
queryDefinition.setCollections(collections);
queryManager.delete(queryDefinition);

堆栈跟踪

DeleteQueryDefinition应该只接受一个集合。

换句话说，DeleteQueryDefinition接受多个集合是Java API中的一个设计错误。

要删除多个收藏集，您可以多次拨打queryManager.delete()。

希望有帮助，

无法删除多个集合。
