Error : The security token included in the request is invalid - Windows Phone Using AWS SNS

Question

我正在使用以下代码在 AWS SNS 中将设备 (Windows Phone) 注册为应用程序中的端点

CognitoAWSCredentials cognitoProvider = new CognitoAWSCredentials(UserId,
                       IdentitypoolID,
                       UnAuthRoleARN,
                       AuthRoleARN,
                       Region);

            AmazonSimpleNotificationServiceClient sns = new AmazonSimpleNotificationServiceClient(cognitoProvider.GetCredentials().AccessKey.ToString(),
                cognitoProvider.GetCredentials().SecretKey.ToString(), REgion); //provide credentials here

            var channelOperation = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

            CreatePlatformEndpointRequest epReq = new CreatePlatformEndpointRequest();
            epReq.PlatformApplicationArn = ApplicationArn;
            epReq.Token = channelOperation.Uri.ToString();

            CreatePlatformEndpointResponse epRes = await sns.CreatePlatformEndpointAsync(epReq);

            CreateTopicRequest tpReq = new CreateTopicRequest();

            SubscribeResponse subsResp = await sns.SubscribeAsync(new SubscribeRequest()
            {
                TopicArn = TopicArn,
                Protocol = "application",
                Endpoint = epRes.EndpointArn
            });

创建端点时抛出错误请求中包含的安全令牌无效执行以下代码时

CreatePlatformEndpointResponse epRes = await sns.CreatePlatformEndpointAsync(epReq);

请帮我实现这个。提前致谢

使用以下代码在 AWS SNS 应用程序中注册 windows phone 设备。我可以使用以下代码创建端点。

private async void Push()
        {
            CognitoAWSCredentials cognitoProvider = new CognitoAWSCredentials(UserId,
                   IdentitypoolID,
                   UnAuthRoleARN,
                   AuthRoleARN,
                   Region);

            using (var sns = new AmazonSimpleNotificationServiceClient(credentials, RegionEndpoint.USEast1))
            {
                var channelOperation = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

                CreatePlatformEndpointRequest epReq = new CreatePlatformEndpointRequest();
                epReq.PlatformApplicationArn = "PlatformApplicationARN";
                epReq.Token = channelOperation.Uri.ToString();

                CreatePlatformEndpointResponse epRes = await sns.CreatePlatformEndpointAsync(epReq);

                CreateTopicRequest tpReq = new CreateTopicRequest();

                SubscribeResponse subsResp = await sns.SubscribeAsync(new SubscribeRequest()
                {
                    TopicArn = "TopicARN",
                    Protocol = "application",
                    Endpoint = epRes.EndpointArn
                });

                channelOperation.PushNotificationReceived += ChannelOperation_PushNotificationReceived;
            }
        }
