Question

我正在尝试部署一个侦听通知树的函数，然后向用户发送推送通知。

然而，继续得到这个错误（见下文），我有其他功能正在工作，似乎无法调试。

感谢。

Error: Error occurred while parsing your function triggers.

exports.sendFollowerNotification = functions.database.ref(‘/user_notifications/{userId}/{notificationId}’).onWrite(event => {
                                         ^

这是我的代码功能代码：

'use strict';

const functions = require('firebase-functions'),
  admin = require('firebase-admin'),
  logging = require('@google-cloud/logging')();

admin.initializeApp(functions.config().firebase);

exports.sendFollowerNotification = functions.database.ref(‘/user_notifications/{userId}/{notificationId}’).onWrite(event => {

const userId = event.params.userId;
const notificationId = event.params.notificationId;

const getDeviceTokensPromise = admin.database().ref(`/users/${userId}’).once('value');

const getNotificationPromise = admin.database().ref(‘/notifications/${notificationId}’).once('value');

return Promise.all([getDeviceTokensPromise, getNotificationPromise]).then(results => {

    const userSnapshot = results[0];
    const notification = results[1];

if (!userSnapshot.hasChildren()) {

        return console.log('There is no user to send to.');

    }

const payload = {
        notification: {
            title: ‘Covet Notification!’,
            body: `${notification.description}`,
        sound: 'default',
                badge: '1'
         }
 };

const token = userSnapshot.pushToken

return admin.messaging().sendToDevice(token, payload)

}); 

});
