如何获取只读玩家数据

public void GetUserReadOnlyData()
{
    PlayFabServerAPI.GetUserReadOnlyData(new GetUserDataRequest()
    {
        PlayFabId = "user PlayFabId here - obtained from any successful LoginResult",
    },
    result => {
        if(result.Data == null || !result.Data.ContainsKey("Sister")) Debug.Log("No Sister");
        else Debug.Log("Sister: "+result.Data["Sister"].Value);
    },
    error => {
        Debug.Log("Got error getting read-only user data:");
        Debug.Log(error.GenerateErrorReport());
    });
}
