物联网 - 无法让 Google IoT Core 工作 - 吾爱随笔录

有没有人在他们的快速入门中得到这个例子？他们提供了 NodeJS 代码来连接到他们的 MQTT 桥，但对我来说它不起作用：

[root@centos7 google-iot-mqtt]# node cloudiot_mqtt_example_nodejs.js \
>     --project_id=curious-furnace-181313 \
>     --registry_id=my-registry \
>     --device_id=mimic1 \
>     --private_key_file=./rsa_private.pem \
>     --algorithm=RS256
Google Cloud IoT Core MQTT example.
connect { '0': {},
   '1': 
   { [Function: require]
 resolve: [Function: resolve],
 main: 
  Module {
    id: '.',
    exports: {},
    parent: null,
    filename: '/home/tmp/uwe/google-iot-mqtt/cloudiot_mqtt_example_nodejs.js',
    loaded: true,
    children: [Object],
    paths: [Object] },

（数千行堆栈跟踪）并且 Google IoT Core 仪表板中没有活动，任何拉取订阅中也没有任何消息。

mosquitto_pub 返回一个奇怪的错误：
