如何从Firebase Unity C#中的数据快照获取密钥?

问题描述

我正在尝试使用Unity和Firebase SDK构建游戏.我想获取图像中的圆圈键.

I am trying to build a game using Unity and Firebase SDK. I want to get the key of circles in the image.

    FirebaseDatabase.DefaultInstance
      .GetReference("live_games")
      .OrderByChild("gameId").EqualTo(GAME_KEY)
      .GetValueAsync().ContinueWith(task => {
          if (task.IsFaulted)
          {
              // Handle the error...
          }
          else if (task.IsCompleted)
          {
              DataSnapshot snapshot = task.Result;
              Debug.Log("the json " + snapshot.GetRawJsonValue());
              Debug.Log("the key is "+ snapshot.Key);
              // Do something with snapshot...
          }
      });

我得到的密钥是"live_games"而不是"0"

I get the key as "live_games" not "0"

Thanks Doug Stevenson it worked

    FirebaseDatabase.DefaultInstance
      .GetReference("live_games")
      .OrderByChild("gameId").EqualTo(GAME_KEY)
      .GetValueAsync().ContinueWith(task => {
          if (task.IsFaulted)
          {
              // Handle the error...
          }
          else if (task.IsCompleted)
          {
              DataSnapshot snapshot = task.Result;
              foreach(var child in snapshot.Children)
              {
                  Debug.Log("The Key"+child.Key);
              }
              // Do something with snapshot...
          }
      });
