Cognito上的未认证问题

Question

目标:基本上，我希望使用用户的STS凭证(访问、密钥、会话密钥)来检索用户属性/身份ID。我正在编写一个java servlet (服务器端)，而我的客户机正在通过HTTP传递STS凭证。

问题:我在servlet上遇到了未经验证的问题。下面是我的Java代码。

BasicSessionCredentials bsccreds = new BasicSessionCredentials(access, secret, session);
        AmazonCognitoSyncClient cogni = new AmazonCognitoSyncClient(bsccreds);

        AmazonCognitoIdentity identityClient = new AmazonCognitoIdentityClient(bsccreds);
        GetIdRequest idRequest = new GetIdRequest();
        idRequest.setRequestCredentials(bsccreds);
        idRequest.setAccountId("51xxxxxxxx");
        idRequest.setIdentityPoolId("us-east-1:xxxxxx-xxxx-xxxx-xxxxxxxxx");

        GetIdResult idResp = identityClient.getId(idRequest); // this line is giving unauthenticated issues even though i pass the STS credentials.
        String uuid = idResp.getIdentityId();
        ListRecordsRequest lrr = new ListRecordsRequest(); 
        lrr.setIdentityPoolId("us-east-1:xxxxxx-xxxx-xxxx-xxxxxxxxx");

        ListRecordsResult lrr_res = cogni.listRecords(lrr);

这是在lambda方法中吗？IAM用户是否有权限使用cognito？
