在昨天我們把資料寫入了firebase，接下來我們再利用googleHomeTrigger 藉由onUpdate進行傳遞訊息

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))
    });

接著新增:

• beforeCoachMessage

• afterCoachMessage
  (因並非與其他生理狀態寫在同一個map裡)
  當coachMessage update 讓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 {
           //生理數據不變
           physiologicalState = 0
  
       }
       return physiologicalState
   }
  

再新增switch case=>當physiological state=8時，產生如下的message

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

即可完成傳送coach message
