using UnityEngine;
using Firebase;
using Firebase.Database;
using Firebase.Unity.Editor;

public class FirebaseManager : MonoBehaviour
{
    DatabaseReference databaseReference;

    void Start()
    {
        // 初始化Firebase
        FirebaseApp.DefaultInstance.SetEditorDatabaseUrl("YOUR_DATABASE_URL");
        databaseReference = FirebaseDatabase.DefaultInstance.RootReference;

        // 请求数据
        RequestData();
    }

    void RequestData()
    {
        // 监听数据变化
        databaseReference.Child("your_node").ValueChanged += HandleValueChanged;
    }

    void HandleValueChanged(object sender, ValueChangedEventArgs args)
    {
        if (args.DatabaseError != null)
        {
            Debug.LogError(args.DatabaseError.Message);
            return;
        }

        // 获取返回的字符串数据
        string result = args.Snapshot.Value.ToString();
        Debug.Log("返回的字符串数据：" + result);
    }
}
