移动消息属性
问题
您想将消息属性移动到另一个属性。
解决方案
使用 Change 节点来移动属性。
示例
[{"id":"d11f7311.77c15","type":"inject","z":"535331d8.55c1f","name":"","topic":"Hello","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"x":160,"y":280,"wires":[["13c01487.eb13cb"]]},{"id":"13c01487.eb13cb","type":"change","z":"535331d8.55c1f","name":"","rules":[{"t":"move","p":"topic","pt":"msg","to":"payload","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":360,"y":280,"wires":[["89cc4fb1.9b208"]]},{"id":"89cc4fb1.9b208","type":"debug","z":"535331d8.55c1f","name":"","active":true,"console":"false","complete":"false","x":550,"y":280,"wires":[]}]
讨论
Change 节点可用于移动消息的属性。
这可以在 Change 节点中作为两个单独的操作完成；首先使用 Set 动作将属性复制到新位置，然后使用 Delete 动作删除原始属性。
或者，该节点支持一个 Move 动作，一步即可完成。
