属性 Event 的值必须是 S3 存储桶的 TopicConfigurations 中 CloudFormation 中的字符串类型

Question

我在 cloudformation 模板中有这段代码：

     "MyBucket": {
     "Type" : "AWS::S3::Bucket",
     "Properties" : {
     "NotificationConfiguration": {
              "TopicConfigurations": [
                {
                  "Event": ["s3:ObjectCreated:Put" , "s3:ObjectCreated:Post"], 
                  "Topic": { "Ref": "TopicSNS" }
                }
              ]
            }
}
}

通过在 CloudFormation 中创建堆栈测试此代码后，我收到此错误：Value of property Event must be of type String 并且创建失败。 这样做的理由是什么？ 谢谢

您将列表传递给Event 属性，但Event requires a string value。要配置多个事件，请创建多个 TopicConfigurations 对象：

"MyBucket": {
  "Type": "AWS::S3::Bucket",
  "Properties": {
    "NotificationConfiguration": {
      "TopicConfigurations": [
        {
          "Event": "s3:ObjectCreated:Put",
          "Topic": {
            "Ref": "TopicSNS"
          }
        },
        {
          "Event": "s3:ObjectCreated:Post",
          "Topic": {
            "Ref": "TopicSNS"
          }
        }
      ]
    }
  }
}
