Question

我正在使用根据以下方案存储数据的数据库：

root:
   currentTime
   users:
      <some user id>:
         <value1>
         <value2>
      <some other id>:
         <value1>
         <value2>

我希望每个用户只能在各自的user_id文件夹下编辑值。我的规则配置如下：

{
  "rules": {
    "currentTime": {
      ".read" : "auth != null",
      ".write" : "auth != null",
      ".validate" : "newData.isNumber() && newData.val() > 0"
    },
    "users": {
      "$u_id": {
        ".read": "auth != null && $u_id === auth.uid",
        ".write": "auth != null && $u_id === auth.uid"
      }
    }
  }
}

用户的任何读取或写入请求都会被拒绝权限，但是如果我删除了“ $ u_id === auth.uid”条件，那么一切似乎都可以正常工作。用户在我手动检查的user_id文件夹下写入值，该值与firebase用户选项卡中的uid相同，因此我不明白为什么该条件无法通过。如果有帮助，这是我用于连接数据库的代码：

LD.LogMessage("Connecting to database");
    authCode = PlayGamesPlatform.Instance.GetServerAuthCode();
    Firebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;
    Firebase.Auth.Credential credential =
        Firebase.Auth.PlayGamesAuthProvider.GetCredential(authCode);
    auth.SignInWithCredentialAsync(credential).ContinueWith(task => {
        if (task.IsCanceled) {
            Debug.LogError("SignInWithCredentialAsync was canceled.");
            return;
        }
        if (task.IsFaulted) {
            Debug.LogError("SignInWithCredentialAsync encountered an error: " + task.Exception);
            return;
        }

        Firebase.Auth.FirebaseUser newUser = task.Result;
        Debug.LogFormat("User signed in successfully: {0} ({1})",
            newUser.DisplayName, newUser.UserId);
        reference = FirebaseDatabase.DefaultInstance.RootReference;
        userId = newUser.UserId;
        LD.LogMessage("Successfully connected");
        LD.canLoad = true;
    });

通过Play Games进行身份验证后，Firebase实时数据库无法匹配uid
