使用React Native从Firebase获取数据

import firebase from 'firebase';

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"
};

firebase.initializeApp(firebaseConfig);

import firebase from 'firebase';

// 获取实时数据库引用
const database = firebase.database();

// 获取数据
database.ref('path/to/data').once('value')
  .then(snapshot => {
    const data = snapshot.val();
    // 处理获取到的数据
  })
  .catch(error => {
    // 处理错误
  });
