<!-- 添加其他所需的Firebase模块，如云存储等 -->

<script>
  // 替换为您的配置信息
  var firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_AUTH_DOMAIN",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_STORAGE_BUCKET",
    messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
    appId: "YOUR_APP_ID"
  };

  // 初始化Firebase
  firebase.initializeApp(firebaseConfig);
</script>

<script>
  // 获取实时数据库引用
  var database = firebase.database();

  // 在数据库中读取数据示例
  var ref = database.ref("path/to/data");
  ref.on("value", function(snapshot) {
    var data = snapshot.val();
    // 处理数据
  });
</script>
