Firesharp：执行请求时出错。路径：0/，方法：PUT

Question

我正在使用 C# 探索 Firebase 实时数据库 (RTDB)，并在 .NET 控制台应用程序上试用 Firesharp 框架。我已按照大多数在线入门教程进行操作，但无法 post 向我的 RTDB 发送任何数据。我在 AddData().Wait():

处抛出此错误

System.AggregateException has been thrown

"One or more errors occurred. (An error occured while execute request. Path : 0/ , Method : PUT)"

我的实现是这样的：

class Program
{
    static IFirebaseConfig config = new FirebaseConfig
    {
        AuthSecret="MY_AUTH_SECRET",
        BasePath="https://MY_APP.firebaseio.com/"
    };

    static IFirebaseClient client;

    static void Main(string[] args)
    {
        Console.WriteLine("Hello World!");
        client = new FireSharp.FirebaseClient(config);

        if (client != null)
        {
            Console.WriteLine("Connection established!");
            AddData().Wait(); //Crashed here with above error
        }
    }

    public static async Task AddData() 
    {
        var data = new Data
        {
            id = "Hello",
            text = "World"
        };

        SetResponse response = await client.SetAsync("0/", data);
        Data result = response.ResultAs<Data>();
    }
}

我是 C# 的新手。我哪里做错了？

我在 Mac 上使用 VS，因此没有编写表单应用程序来进行测试。

好的，所以这个问题的问题是我安装了两个 Nuget 包，Firesharp 和 Firesharp.Serialization.JsonNet。

我删除了 Firesharp，然后修改了我的 AddData() 函数，一切正常。

public static async Task AddData() 
{
    var data = new Data
    {
        id = "Hello",
        text = "World"
    };

    SetResponse response = await client.SetTaskAsync("0", data); //Change to SetTaskAsync here
    Data result = response.ResultAs<Data>();
}

Firesharp：执行请求时出错。路径：0/，方法：PUT

Firesharp: An error occured while execute request. Path : 0/ , Method : PUT
