如何使用Firebase云端功能增加徽章数量

Question

现在我的有效负载仅发送1个徽章数量，徽章数量的值不会增加。它仍然是1，即使你得到超过1个通知。

javascript应该怎么写？

我当前的代码：

const functions = require('firebase-functions');     
const admin = require('firebase-admin'); 
admin.initializeApp(functions.config().firebase); 
exports.sendPushForHelp = 
functions.database.ref('/help/school/{id}').onWrite(event => { 
    const payLoad = { 
    notification: { 
     title: 'Someone', 
     body: 'needs help', 
     badge: '1', 
     sound: 'Intruder.mp3' 
    } 
    }; 
    return admin.database().ref('fcmToken').once('value').then(allToken => { 
     if (allToken.val()) { 
     const token = Object.keys(allToken.val()); 
     return admin.messaging().sendToDevice(token, payLoad).then(response => { 

      }); 
     }; 
    }); 
});

您可以存储在您的JS badgeCount并让它在每次调用增加，或随机，或你有什么

即：

const functions = require('firebase-functions');     
const admin = require('firebase-admin'); 
admin.initializeApp(functions.config().firebase); 
var badgeCount = 1; 
exports.sendPushForHelp = 
functions.database.ref('/help/school/{id}').onWrite(event => { 
    const payLoad = { 
    notification: { 
     title: 'Someone', 
     body: 'needs help', 
     badge: badgeCount.toString(), 
     sound: 'Intruder.mp3' 
    } 
    }; 
    badgeCount++; //or whatever 
    return admin.database().ref('fcmToken').once('value').then(allToken => { 
     if (allToken.val()) { 
     const token = Object.keys(allToken.val()); 
     return admin.messaging().sendToDevice(token, payLoad).then(response => { 
      //here might be a good place to increment as well, only on success 
      }); 
     }; 
    }); 
});
