Question

我正在尝试使用Firebase函数将配置发送到Iot设备。这是我正在尝试使用的教程。这是我正在部署的Node js代码

该教程说，部署后，无论我对Firebase数据库进行什么更改，它都将作为设备配置发送到物联网设备。

注册号是INTERNET_OF_BULBS。物联网设备名称为“ Iot-device-1”。

教程中的实际代码不适用于部署。因此，我删除了导入模块部分，并使用了require。本教程将执行这些导入。

import * as admin from "firebase-admin";
import * as functions from 'firebase-functions';
import { runInDebugContext } from 'vm';
import { DeviceManager } from './devices';
how do i import { DeviceManager } from './devices';

所以我只做2次import。否则，如果我在我的index.js中使用import，则部署时会出错。 1：1错误解析错误：“导入”和“导出”可能仅与“ sourceType：模块”一起出现下面是我的index.js文件。

const admin =require('firebase-admin');
const functions =require('firebase-functions');

admin.initializeApp();

// create a device manager instance with a registry id, optionally pass a region
const dm = new DeviceManager('INTERNET_OF_BULBS');
const firestore = admin.firestore();
// start cloud function
exports.configUpdate = functions.firestore
  // assumes a document whose ID is the same as the deviceid
  .document('device-configs/Iot-device-1')
  .onWrite((change,context) => {
    var beforeData = change.before.val(); // data before the write
    var afterData = change.after.val();
    if (context) {
      await dm.setAuth();
      console.log(context.params.deviceId);
      // get the new config data
      const configData = change.after.data();
      return dm.updateConfig(context.params.deviceId, configData);
    } else {
      throw(Error("no context from trigger"));
    }

  })

当我尝试部署上面的代码时，这是我的外壳上的错误。
