Unity API実装で値ちゃんと受け取れてるか確認

↓C#の頭いいやつが作ったリフレクションで変数群取れるやつ用意する

        if (o is IEnumerable)
            return ("...");

        return ("{ }");
    }
}
```

使い方

```c#:Example.cs
//データ表示したい型をuserに代入するとstringに変換される
var dump = ObjectDumper.Dump(user);
```
使用例

```c#:TestAPI.cs
using NetworkAPI;
using UnityEngine;
using UnityEngine.UI;

public class TestAPI : MonoBehaviour
{

    Text test;
    // Start is called before the first frame update
    void Start()
    {
        test = this.gameObject.GetComponent<Text>();
        //API送るなにか作った想定
        APIManager.Api(hoge, GetRanking_Success, GetRanking_Failure);
    }
    private void GetRanking_Failure(NetworkStatus status, int bizerror, string bizerrormessage)
    {
        test.text = "失敗\nサーバーのURL接続の設定合ってますか？\n";
    }
    private void GetRanking_Success(object data)
    {
        //受け取りたい型として変換
        GetRankingResponseForm getData = data as GetRankingResponseForm;
        //受け取った型をstringに変換
        string dump = ObjectDumper.Dump(getData);
        //表示
        test.text = "成功\n"+dump;

    }
   
}
```

だいたいこんな感じでそれぞれのAPIごとにテストシーン作ってくといいかも
