所以,我有一个dynamoDB表用户和我想要返回此表的所有内容.或者甚至是一些.

我试过了

aws dynamodb query --table-name Users 

它说我必须指定key-condition或key-condition-expression所以我添加了以下内容:

aws dynamodb query --table-name Users --key-condition-expression Username = "test"

并返回错误消息"未知选项:测试"

有人可以告诉我一个有效的关键条件表达式.我试图在一个名为MyKeyTable的简单表上运行查询.它有两个"列",即Id和AnotherNumberThatICareAbout,类型为Long.

我想看看我投入的所有价值观.所以我尝试过:

aws dynamodb query --select ALL_ATTRIBUTES --table-name MyKeyTable
--endpoint http://localhost:8000 
--key-condition-expression "WHAT DO I PUT IN HERE?"

我需要放入什么哈希？文档对这个imho有点蹩脚.任何帮助表示感谢,即使它只是一个好文档的链接.

我有 ~/.aws/credentials 和配置文件，我的代码如下

clientConfiguration.setProxyHost("MYPROXY");
            clientConfiguration.setProxyPort(port);
            clientConfiguration.setProxyUsername("username");
            clientConfiguration.setProxyPassword("pw");
            clientConfiguration.setPreemptiveBasicProxyAuth(false);


            AmazonDynamoDBClient client = new AmazonDynamoDBClient(new ProfileCredentialsProvider("MY_PROFILE"),clientConfiguration);

         //client.withRegion(Regions.US_EAST_1);
         DynamoDBMapper mapper = new DynamoDBMapper(client);

         // Get a book - Id=101
         GetBook(mapper, 101);

我每次都遇到异常。我可以在 ~/.aws/credentials 的凭证文件中看到会话令牌

我正在使用 Amazon-SQS，我尝试从队列中检索近似数量的属性，但响应为空

我正在使用 C# 以下是代码：

GetQueueAttributesRequest attReq = new GetQueueAttributesRequest();
attReq.QueueUrl = "Link to queue";
GetQueueAttributesResponse response = client.GetQueueAttributes(attReq);
Console.WriteLine("App. messages: "+ response.ApproximateNumberOfMessages);

我从请求中得到空响应，我确定队列中也有消息。
