从无服务器功能中获取 SQS URL 名称？

问题描述

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 https://sqs.us-east-1.amazonaws.com/xxxx/channels.fifo 设置为 SQS_URL，而不是 arn channels.fifo。我查看了 cloudformation 的 Fn::Split fucntion，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'

解决方法

如果您查看 SQS::Queue CloudFormation resource，您可以看到队列名称作为属性公开。

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

我能够通过替换来实现它

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

部分与

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

现在给我的输出是 channels.info 而不是 https://sqs.us-east-1.amazonaws.com/xxxx/channels.fifo
