从Firebase实时数据库获取url值

// firebaseConfig.js
export const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  databaseURL: "YOUR_DATABASE_URL",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

// index.js
import { initializeApp } from 'firebase/app';
import { getDatabase, ref, onValue } from 'firebase/database';
import { firebaseConfig } from './firebaseConfig';

const app = initializeApp(firebaseConfig);
const database = getDatabase(app);

{
  "urls": {
    "exampleUrl": "https://example.com"
  }
}

// 获取URL值
const urlRef = ref(database, 'urls/exampleUrl');

onValue(urlRef, (snapshot) => {
  const url = snapshot.val();
  console.log('URL:', url);
}, (error) => {
  console.error('Error fetching URL:', error);
});

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}
