DynamoDB 请求中包含的安全令牌无效 UnrecognizedClientException

Question

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

从简单的事情开始。您检查过文件的权限吗？至少在 Linux 中，它们需要是 600 或用户读/写、组和世界无访问权限。

您是否检查过 AWS 端以验证这些凭证是否与您尝试使用的账户关联？

您可以运行使用凭据的简单命令吗？Amazon 的CLIaws命令是一个完美的起点。

aws ec2 help

先检查一下就好了。然后尝试访问一些普遍可用的信息，例如现货 EC2 实例价格历史记录：

aws ec2 describe-spot-price-history --prod "Linux/UNIX" --start-time 2016-08-15

应该会给你数千行输出。然后尝试访问您自己的帐户信息：

aws ec2 describe-instances

此时，您知道 CLI 一切正常。下一步是完全 Java 连接，如果您从同一台计算机上运行它，并使用 ~/.aws/ 所在的相同主目录，那么它现在应该可以工作。

我每天都使用 Java 进行 DynamoDB 访问。一旦你清除了一些障碍，它就会发挥很大的作用。
