Unity&中的RawJsonValues火力基地 [英] RawJsonValues in Unity & Firebase

问题描述

SetRawJsonValueAsync的某些问题.当我使用文档中的代码时:

Some problems with the SetRawJsonValueAsync. When I use the code from documentation:

    public class User
{
    public string username;
    public string email;

    public User()
    {
    }

    public User(string username, string email)
    {
        this.username = username;
        this.email = email;
    }
}

private void writeNewUser(string userId, string name, string email)
{
    User user = new User(name, email);
    string json = JsonUtility.ToJson(user);

    mDatabaseRef.Child("users").Child(userId).SetRawJsonValueAsync(json);
}

然后，firebase自动将其转换为值树.好的.但是当我试图让他们回来时:

Then firebase automatically converts it to the tree of values. Ok. But when i'm trying to get them back:

    public void get_data()
{
    mDatabaseRef.Child("users").Child(userId).GetValueAsync().ContinueWithOnMainThread(task => {
        if (task.IsCompleted)
        {
            Debug.Log("completed");
            string json = task.Result.Value;
            User user = JsonUtility.FromJson<User>(json);
            Debug.Log(user.username);
        }
    });
}

它停止并且不打印用户名.为什么?还是我需要获取JSON原始数据?

it stops and doesn't print username. Why? Or how i need to get json raws?

推荐答案

此处的问题是您想要的是 task.Result.GetRawJsonValue() :

What you want is task.Result.GetRawJsonValue():

public void get_data()
{
    mDatabaseRef.Child("users").Child(userId).GetValueAsync().ContinueWithOnMainThread(task => {
        if (task.IsCompleted)
        {
            Debug.Log("completed");
            string json = task.Result.GetRawJsonValue();
            User user = JsonUtility.FromJson<User>(json);
            Debug.Log(user.username);
        }
    });
}
