当我订阅连接影子的动态主题时。我无法建立连接设备。没有订阅它已连接但无法接收消息有效负载。

代码

this.thingShadows = new awsiot.thingShadow({
  keyPath: keyPath,
  certPath: certPath,
  caPath: caPath,
  clientId: clientId, //"sdk-nodejs-" + clientId,
  host: host,
  debug: true,
});

this.thingShadows.subscribe(clientId + "/*");

政策

 {
  "Effect": "Allow",
  "Action": [
    "iot:Connect"
  ],
  "Resource": [
    "arn:aws:iot:ap-south-1:453533943651:client/${iot:Connection.Thing.ThingName}"
  ]
},
{
  "Effect": "Allow",
  "Action": [
    "iot:Publish"
  ],
  "Resource": [
    "arn:aws:iot:us-south-1:453533943651:topic/${iot:Connection.Thing.ThingName}/*"
  ]
},
{
  "Effect": "Allow",
  "Action": [
    "iot:Subscribe"
  ],
  "Resource": [
    "arn:aws:iot:us-south-1:453533943651:topicfilter/${iot:Connection.Thing.ThingName}/*"
  ]
},
{
  "Effect": "Allow",
  "Action": [
    "iot:Receive"
  ],
  "Resource": [
    "arn:aws:iot:ap-south-1:453533943651:topic/${iot:Connection.Thing.ThingName}/*"
  ]
}

是的，您无法订阅动态主题，您必须将策略“arn:aws:iot:ap-south-1:453533943651:topic/${iot:Connection.Thing.ThingName}/*”更改为 *..允许所有设备。然后您可以订阅.topic/${iot:Connection.Thing.ThingName} 这表示事物名称应该位于主题的末尾。更改以允许您订阅所有内容。
