是否可以一次查询firebase (node.js)中的多个键？

const admin = require('firebase-admin');
admin.initializeApp();

const database = admin.database();
const ref = database.ref('your/path/to/data');

const keys = ['key1', 'key2', 'key3'];

ref.child(keys.join('/')).once('value', (snapshot) => {
  const values = snapshot.val();
  console.log(values);
});

const admin = require('firebase-admin');
admin.initializeApp();

const firestore = admin.firestore();
const collection = firestore.collection('your-collection');

const keys = ['key1', 'key2', 'key3'];

const promises = keys.map((key) => {
  const docRef = collection.doc(key);
  return docRef.get();
});

Promise.all(promises)
  .then((snapshots) => {
    const values = snapshots.map((snapshot) => snapshot.data());
    console.log(values);
  })
  .catch((error) => {
    console.error(error);
  });
