amazon-web-services - 通过Cloudformation创建SQS队列及其访问策略时出错

Question

我正在尝试使用 cloudformation 创建 SQS 队列及其关联的访问策略。尝试了几次迭代，但它一直给我这个错误:

Value of property Queues must be of type List of String

下面是我的模板。谁能帮我指出这个问题:

    SQSQueue:
        Type: "AWS::SQS::Queue"
        Properties:
            DelaySeconds: "0"
            MaximumMessageSize: "262144"
            MessageRetentionPeriod: "10800"
            ReceiveMessageWaitTimeSeconds: "0"
            VisibilityTimeout: "30"
            QueueName: "ScanQueueItems"

    DocSQSSNSPolicy:
        Type: AWS::SQS::QueuePolicy
        Properties:
            PolicyDocument:
                Id: MessageToSQSPolicy
                Statement:
                    Effect: Allow
                    Principal: "*"
                    Action:
                        - SQS:SendMessage
                    Resource: !GetAtt SQSQueue.Arn  
            Queues: !Ref SQSQueue

Answer 1

Queues应该是字符串列表。这意味着而不是:

Queues: !Ref SQSQueue

你应该有:

Queues: 
    - !Ref SQSQueue

或更短:

Queues: [!Ref SQSQueue]
