在 Watson IoT Platform 上的规则后未触发 Node-RED 操作

Question

我目前正在使用 Watson IoT Platform 从我的 raspberrypi 收集数据。

如果规则被激活，我会根据阈值和三个操作创建一个规则：

• 第一个是调用 Bluemix 上的 Node-RED 节点的 Node-RED 操作
• 第二个是另一个 Node-RED 操作，在我的树莓派上调用 Node-RED 节点
• 第三个是简单的“发送邮件”

在始终正确发送电子邮件时，永远不会触发前两个操作。

我在 BlueMix 上的 Node-RED 节点位于以下 url：https://xxx.eu-gb.mybluemix.net，http 端点是 /command，所以我配置的 URL 是 https://xxx.eu-gb.mybluemix.net/command。

这个配置有什么问题？

谢谢，

迭戈

Answer 1

节点中的http必须使用POST作为方法。这是一个示例流程，当触发写入调试节点时。
