如何将对象存储为字符串? [英] How to store object as string?

问题描述

我以前从未使用过Firebase，并且正在尝试将实时数据库连接到我的Unity应用程序.现在，我的应用程序从Json文件中提取数据并将其存储为字符串.为了避免破坏程序的其余部分(我是编程新手，没有技能来重写，但是正在学习)，我想将Firebase快照转换为字符串并以当前Json的方式读取它文件是.那可能吗?快照是一个目标文件，我需要从中获取字符串数据.

I've never used Firebase before, and am trying to connect a real-time database to my Unity app. Right now my app pulls data from a Json file and stores it as a string. To avoid breaking the rest of my program (I'm very new to programming and don't have the skills to rewrite it, but am learning), I want to convert the Firebase snapshot into a string and read it the way my current Json file is. Is that possible? The snapshot is an object file, and I need to get the string data from it.

这是捕获快照的代码.

DataSnapshot snapshot = task.Result;

我也声明了这个字符串.

I also have this string declared.

private string gameDataFileName = "data.json";

然后这是从文件加载数据的功能.

Then this is the function to load the data from the file.

private void LoadGameData()
{
    string filePath = Path.Combine(Application.streamingAssetsPath, 
    gameDataFileName);

    if (File.Exists(filePath))
    {
        string dataAsJson = File.ReadAllText(filePath);
        GameData loadedData = JsonUtility.FromJson<GameData>(dataAsJson);

        allRoundData = loadedData.allRoundData;
    }
    else
    {
        Debug.LogError("Cannot load game data!");
    }
}

是否有将快照转换为Json或字符串的方法，以便可以将其插入dataAsJson?还是如果没有人能告诉我这样做的正确方法?该应用程序是一款琐事游戏，可在启动该应用程序时下载问题和答案.我不需要刷新数据，我只想能够在不强迫用户下载更新的情况下更新问题，因此我选择使用Firebase.

Is there anyway to convert the snapshot into a Json or string so I can plug it into dataAsJson? Or if not can anyone tell me the proper way to do this? The app is a trivia game that downloads the questions and answers when starting the app. I don't need the data to refresh, I just want to be able to update the questions without forcing the user to download an update, hence my reason for using Firebase.

我应该以其他方式执行此操作吗?我已经搜索了互联网的每个角落，并且阅读的所有内容要么超出我的理解范围，要么在我的情况下不起作用.

Is there a different way I should be doing this? I've searched every corner of the internet and everything I read is either beyond my comprehension or doesn't work in my situation.

推荐答案

要获取DataSnapshot的原始JSON，请调用其

To get the raw JSON of a DataSnapshot call its GetRawJsonValue() method. You should then be able to pass that into your JsonUtility.FromJson method.
