Firepoint 데이터베이스 쿼리가 모든 엔드 포인트에 대해 동일한 데이터를 반환합니다.

Question

새 게시물을 Firebase Realtime Database에 삽입 할 때 모든 장치에 푸시 알림을 보내기위한 Firebase 기능을 만들려고했습니다. 내 장치 토큰은 프로필 알림 끝점 아래에 있습니다. 새 게시물을 데이터베이스에 삽입하여 내 기능을 실행하려고하면 내 응답이 예상치 못한 결과를 낳습니다. https://firebase.google.com/docs/functions/과 https://firebase.google.com/docs/reference/admin/node/admin.database에서 문서를 읽었지만 그 이상은 얻을 수 없었습니다.

내가 볼 수있는 것과 그래서

는 데이터베이스에서 응답이 내가 기대하는 것입니다,하지만 난 내 결과를 기록 할 때, 나는 긴 JSON과를 얻을 : 여기 내 로그는 내가 기대했던 것에 가까운 아무것도. 결제 계정이 없기 때문에 이것이 가능합니까? 누군가가 나를 도울 수 있습니까? 여기 내 코드도 있습니다. jacobawenger는 의견에서 지적

const functions = require('firebase-functions'); 
const admin = require('firebase-admin'); 

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

exports.sendNewPostNotification = functions.database.ref('/posts/{postId}').onWrite(event => { 
    const postId = event.params.postId; 

    admin.database.enableLogging(true); 
    return admin.database().ref("profile-notifications").once('value').then(result => { 
    if (result) { 
     console.log('Result: ', result); // "Stuff worked!" 
    } 
    }, err => { 
    console.log('Error: ', err); // Error: "It broke" 
    }); 
}); 

Answer 1

으로, 문제는 result가 DataSnapshot이라고했다, 그래서 나는 그것의 가치를 얻을 수 result.val()를 추가 할 필요가 있었다.
