正在尝试从另一个firebase数据库检索数据

const admin = require("firebase-admin");
const serviceAccount = require("path/to/serviceAccountKey.json");

// 初始化 Firebase Admin SDK
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://your-project.firebaseio.com"
});

// 获取数据库引用
const db = admin.database();
const ref = db.ref("path/to/data");

// 读取数据
ref.once("value")
  .then((snapshot) => {
    const data = snapshot.val();
    console.log(data);
  })
  .catch((error) => {
    console.error(error);
  });

const admin = require("firebase-admin");
const serviceAccount = require("path/to/serviceAccountKey.json");

// 初始化 Firebase Admin SDK
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://your-project.firebaseio.com"
});

// 获取数据库引用
const db = admin.firestore();
const docRef = db.collection("collectionName").doc("documentId");

// 读取数据
docRef.get()
  .then((doc) => {
    if (doc.exists) {
      const data = doc.data();
      console.log(data);
    } else {
      console.log("No such document");
    }
  })
  .catch((error) => {
    console.error(error);
  });
