AWS IoT Core 规则引擎和 AWS IoT Events

以下规则将 AWS IoT Events MQTT 消息作为影子更新请求消息重新发布。我们假设 AWS IoT Core 为由探测器模型控制的每个区域定义了加热装置和冷却装置。

在此示例中，我们定义了名为 Area51HeatingUnit 和 Area51CoolingUnit 的元素。

使用的 CLI 命令：

aws iot create-topic-rule --cli-input-json file://ADMShadowCoolOffRule.json

文件：ADMShadowCoolOffRule.json

{
  "ruleName": "ADMShadowCoolOff",
  "topicRulePayload": {
    "sql": "SELECT topic(3) as state.desired.command FROM 'hvac/Cooling/Off'",
    "description": "areaDetectorModel mqtt topic publish to cooling unit shadow request",
    "ruleDisabled": false,
    "awsIotSqlVersion": "2016-03-23",
    "actions": [
      {
        "republish": {
          "topic": "$$aws/things/${payload.detector.keyValue}CoolingUnit/shadow/update",
          "roleArn": "arn:aws:iam::123456789012:role/service-role/ADMShadowRole" 
        }
      }
