为 MQTT 连接 AWS 服务器时出现异常

Question

I have tried to run example from https://github.com/awslabs/aws-sdk-android-samples/blob/master/AndroidPubSub/README.md . I have changed PoolId , End Server and Policy Name . I am getting following exception.

Exception occurred when generating new private key and certificate. com.amazonaws.AmazonServiceException: 1 validation error detected: Value 'us-west-2_something' at 'identityPoolId' failed to satisfy constraint: Member must satisfy regular expression pattern: [\\w-]+:[0-9a-f-]+ (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: ValidationException; Request ID: f7c3924a-e847-11e6-8508-ab41b4890740)

Answer 1

您需要转到 Cognito 控制台并创建一个 Cognito 身份池并将us-west-2_something替换为实际身份池 ID，如下所示us-west-2:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
