【问题描述】：

我正在尝试使用 thingsboard 物联网网关连接到 thingsboard 服务器。我已遵循以下链接中给出的所有步骤：https://thingsboard.io/docs/iot-gateway/install/source-installation/

使用命令运行 tb-gateway 时：python3 ./thingsboard_gateway/tb_gateway.py 我收到以下错误消息：

 INFO - [mqtt_connector.py] - mqtt_connector - 157 - Number of rejected mapping handlers: 0"

    self._client.connect(self.__host, self.__port, keepalive=keepalive)

我在各个文件中做了以下更改：

mqtt.json：

  "broker": {
    "name":"Default Local Broker",
    "host":"IP Address",
    "port":1883,
    "clientId": "ThingsBoard_gateway",
    "security": {
      "type": "basic",
      "username": "**********",
      "password": "***********"
    }
  }

tb_gateway.yaml：

  host: "IP Address"
  port: 1883
  remoteShell: false
  remoteConfiguration: false
  security:
    accessToken: ********************
  qos: 1
storage:
  type: memory
  read_records_count: 100
  max_records_count: 100000
connectors:

    name: MQTT Broker Connector
    type: mqtt
    configuration: mqtt.json

感谢您的帮助。提前致谢。

【解决方案1】：

你有服务器吗？我来解释一下我的方法。例如我有一个 TCP 服务器。但是我不能直接连接我的 TCP 服务器作为 thingsboard 的客户端。但是每个人都可以作为 mqtt 客户端连接到 thingsboard。只有一个角色，您需要在 thingsboard 中知道您的设备访问令牌。如果您知道访问令牌，您可以使用mqtt://demo.thingsboard.io, { username: "ACCESS_TOKEN" } url 和v1/devices/me/telemetry 主题作为客户端连接到thingboard。使用 node.js 运行的示例 js 代码。 var client = mqtt.connect('mqtt://demo.thingsboard.io' + { username: "AccessToken" }); 并发布client.publish('v1/devices/me/telemetry', JSON.stringify(data));
