Day30 利用web发送讯息(下)

在昨天我们把资料写入了firebase，接下来我们再利用googleHomeTrigger 藉由onUpdate进行传递讯息

exports.googleHomeTrigger = functions.firestore.document('personal-accounts/{firebaseId}/peoples/{tagMac}')
    .onUpdate(async (change, context) => {

        const beforeData = change.before.data() as peopleInterface
        const afterData = change.after.data() as peopleInterface

        // const firebaseId = context.params.firebaseId
        // const tagMac = context.params.tagMac
        const physiologicalState = verifyPhysiologicalState(beforeData, afterData)
        // const moudule = getLocation(afterData)
        await notifyPhysiological(physiologicalState, afterData)
    .catch(err =>console.log(err))
    });

接着新增:

• beforeCoachMessage

• afterCoachMessage
  (因并非与其他生理状态写在同一个map里)
  当coachMessage update 让physiologicalState = 8

    const verifyPhysiologicalState = (beforeData: peopleInterface, afterData: peopleInterface): number => {
       let physiologicalState
  
   const beforePhysiological = beforeData.physiological
   const afterPhysiological = afterData.physiological
   const beforeCoachMessage = beforeData.coachMessage
   const afterCoachMessage = afterData.coachMessage
       if (afterPhysiological.HR != beforePhysiological.HR) {
           //心律
           if(afterPhysiological.HR >= 90 || afterPhysiological.HR <= 60){
               physiologicalState = 1
           }
  
       }
       .
       .
       .
       else if (beforeData.coachMessage != afterData.coachMessage) {
  
           physiologicalState = 8
  
       } else {
           //生理数据不变
           physiologicalState = 0
  
       }
       return physiologicalState
   }
  

再新增switch case=>当physiological state=8时，产生如下的message

case 8:
                // notifyMessage = `${afterData.name}血糖为${afterData.physiological?.BS}`
            notifyMessage = {
                tagMAC:afterData.tagMAC,
                name:afterData.name, 
                result:`${afterData.coachMessage}`,
                message:`${afterData.coachMessage}`,
                moudule:arr[0]
            }
            break;

即可完成传送coach message
