错误：请求中包含的安全令牌无效 - 使用AWS SNS的Windows Phone

Question

我使用以下代码在AWS SNS中注册设备（Windows Phone）作为应用程序中的端点

uv

创建端点时，它会抛出错误请求中包含的安全令牌无效，同时执行代码

   /**
     * @return A comma separated list of radios that need to be disabled when airplane mode is on
     */
    private String getGlobalSettingValues() {
        ContentResolver cr = getContentResolver();
        Cursor globalCursor = null;
        String aeroplaneMode = null;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            globalCursor = cr.query(Settings.Global.CONTENT_URI, null, null, null, null);
            if(globalCursor != null && globalCursor.moveToFirst()){
                aeroplaneMode =  Settings.Global.getString(getApplicationContext().getContentResolver(),Settings.Global.AIRPLANE_MODE_RADIOS);
            }
        } 
        if (globalCursor != null) {
            globalCursor.close();
        }
        return aeroplaneMode;
    }

请帮助我实现这一目标。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;
            }
        }
