    "instanceIds": [
      "i-xxx"
    ],
    "lifecycleHookId": "ash-xxx",
    "lifecycleActionToken": "XXXX",
    "scalingGroupId": "asg-xxx",
    "scalingActivityId": "asa-xxx",
    "notificationMetadata": "lifecycleHook metadata example",
    "defaultResult": "CONTINUE"
  }
}

data字段包含的参数解释如下表所示。

参数	类型	示例值	描述
instanceIds	Array	[ "i-xxx" ]	缩容实例ID列表。
lifecycleHookId	String	ash-xxx	生命周期挂钩ID。
lifecycleActionToken	String	XXXX	伸缩活动的等待状态标识符。
scalingGroupId	String	asg-xxx	伸缩组ID。
scalingActivityId	String	asa-xxx	伸缩活动ID。
notificationMetadata	String	lifecycleHook metadata example	生命周期挂钩通知信息。
defaultResult	String	CONTINUE	生命周期挂钩默认结果。取值如下： CONTINUE：继续响应弹性扩张活动或者继续响应弹性收缩活动。 ABANDON：直接释放弹性扩张活动创建出来的ECS实例或者直接将弹性收缩活动中的ECS实例从伸缩组移除。 ROLLBACK：针对弹性收缩活动，会拒绝释放ECS实例，进行回滚；针对弹性扩张活动，会直接释放创建出来的ECS实例，效果同ABANDON一样。
