基础库版本：2.19.2

这个获取mqtt数据的函数是可以在小程序中调用的，当时就是直接传入了全局参数，现在调用就不行了。

// 函数调用
addOrderData:function(event){
    console.log(event);
    console.log('SecretId: ', app.globalData.secretId);
    wx.cloud.callFunction({
      name:'addOrderData',
      data: {
        ProductId: app.globalData.productId,
        DeviceName: app.globalData.deviceName,
        SecretId: app.globalData.secretId,        // 全局变量
        SecretKey: app.globalData.secretKey,
      }
    }).then(res => {
      console.log(res)
    })
}


// 云函数入口文件
const cloud = require('wx-server-sdk')

cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV }) // 使用当前云环境
const db = cloud.database()
const dishesCollection = db.collection('dishes')
const orderCollection = db.collection('order')

// 云函数入口函数
exports.main = async (event, context) => {
  const { productId, deviceName, secretId, secretKey } = event;
  console.log(productId, deviceName, secretId, secretKey);
  // 获取云端数据
  const mqttData = await cloud.callFunction({
    name: 'iothub-shadow-query',
    data: {
      ProductId: productId,
      DeviceName: deviceName,
      SecretId: secretId,        // 这里提示The request is missing a required parameter 'SecretID'
      SecretKey: secretKey,
    }
  });
  let payload = JSON.parse(mqttData.result.Data); 

  // 获取最新order和_id
  const latestOrder = await orderCollection
    .orderBy('_id', 'desc') // 根据_id（创建时间）降序排序
    .limit(1) // 只取一条数据
    .get(); // 获取数据
  const latestOrderId = latestOrder.data[0]._id; // 保存最新订单的 _id
  console.log(latestOrderId);

  // 数据预处理
  let dishes = {};
  // 遍历 payload.state.reported.order
  for (let i = 0; i < payload.state.reported.order.length; i++) {
    // 使用 `dishes_{num}` 作为键，stateReported.order[i] 作为值
    dishes[`dishes_${i+1}`] = payload.state.reported.order[i];
  }

  return await orderCollection.add({
    data: {
      _id: latestOrderId + 1, 
      ...dishes // 使用展开语法将 dishes 对象的所有键-值对添加到 data 对象中
    }
  })
}
