从无服务器功能中获取 SQS URL 名称？

Question

我想获取无服务器函数的名称。这是我的代码。我想要实现的是，我希望将 env SQS_URL 设置为 channels.fifo，而不是 arn https://sqs.us-east-1.amazonaws.com/xxxx/channels.fifo。我查看了 Fn::Split cloudformation 的功能，但无法正确使用它在 env 上进行设置。

functions:
  S3ToSqs:
    handler: lambda_function.lambda_handler
    role: S3ToSqsLambdaRole
    memorySize: 128
    timeout: 5
    events:
      - schedule:
          name: 'S3ToSqsCronEvent'
          rate: rate(1 minute)
          enabled: true
    environment:
      SQS_URL:
        Ref: sqsQueue
      REGION: 'us-east-1'

resources:

Answer 1

我可以通过替换

来实现它

    environment:
      SQS_URL:
        Ref: sqsQueue
      REGION: 'us-east-1'

节

    environment:
      SQS_URL: !Select [4, !Split ["/",!Ref sqsQueue ]]

现在输出为 channels.info 而不是 https://sqs.us-east-1.amazonaws.com/xxxx/channels.fifo

Answer 2

如果您查看 SQS::Queue CloudFormation resource，您会发现队列名称已作为属性公开。

因此，您可以使用：!GetAtt sqsQueue.QueueName 或 Fn::GetAtt [sqsQueue, QueueName]，这两者都比您提出的解决方案（仍然有效）更容易阅读。
