4.读取Resources文件夹下的json文件

5.newtonsoft.Dll下载

6.实体类转json 存本地

1.level1.txt json文件

{
  "level": {
    "floorCount": 2,
    "maxNum": 2,
    "left": 1,
    "right": 1,
    "time":[
        {
            "floor1":0.2
        },
        {
            "floor2":0.5
        }        
    ]
  }
}

2.LevelEntity.cs json实体类

[Serializable]
public class LevelEntity
{
    public int _floorCount;  
    public int _maxNum;     
    public int _left;       
    public int _right;      
    public List<float> _time = new List<float>();  
}

3.读取StreamingAssets文件夹下的json文件

public IEnumerator LoadLevel(string fileName)
    {
        string filePath = "";
        string result = "";
#if UNITY_EDITOR
        filePath = Application.dataPath + "/StreamingAssets/" + fileName + ".txt";
#elif UNITY_IPHONE
        filePath = Application.dataPath +"/Raw/"+fileName+".txt";
#elif UNITY_ANDROID
        //filePath = “jar:file://” + Application.dataPath + “!/assets//"+fileName+".txt";
        filePath = Application.streamingAssetsPath+fileName+".txt";
#endif
        Debug.LogError("FilePath:" + filePath);
        if (filePath.Contains("://"))
        {
            UnityWebRequest www = UnityWebRequest.Get(filePath);
            yield return www.SendWebRequest();
            if (www.isDone == false)
            {
                Debug.LogError("read json error:" + fileName);
            }
            result = www.downloadHandler.text;
        }
        else
        {
            result = System.IO.File.ReadAllText(filePath);
        }
        Debug.Log(result);
 
        JObject jsonData = JObject.Parse(result);
        JToken jToken = jsonData["Data"];
        le = new LevelEntity
        {
            _floorCount = int.Parse(jToken["floorCount"].ToString()),
            _maxNum = int.Parse(jToken["maxNum"].ToString()),
            _random = int.Parse(jToken["random"].ToString()),
            _left = int.Parse(jToken["left"].ToString()),
            _right = int.Parse(jToken["right"].ToString())
        };
    }

上面报错的话，读取方式二：

public IEnumerator LoadConfig(string fileName)
    {
        string filePath = Path.Combine(Application.streamingAssetsPath,fileName);
        string url = "";
 
        if (Application.platform == RuntimePlatform.Android)
        {
            // Android平台的URL前缀
            url = "jar:file://" + filePath;
        }
        else if (Application.platform == RuntimePlatform.IPhonePlayer)
        {
            // iOS平台的URL前缀
            url = "file://" + filePath;
        }
        else
        {
            // 其他平台的URL前缀
            url = "file://" + filePath;
        }
 
        using (UnityWebRequest www = UnityWebRequest.Get(url))
        {
            yield return www.SendWebRequest();
 
            if (www.result == UnityWebRequest.Result.Success)
            {
                // 读取文件成功
                string fileContents = www.downloadHandler.text;
                Debug.Log("文件内容: " + fileContents);
                //ToolClass.DebugInfo("字符串内容是：" + www.downloadHandler.text);
                switch (fileName)
                {
                    case EnumTableName.ZiMuZu:
                        comJson_ZiMuZu = JsonUtility.FromJson<Json_ZiMuZu>(www.downloadHandler.text);
                        cntLoadedConfig++;
                        break;
                }
            }
            else
            {
                // 读取文件失败
                Debug.LogError("读取文件失败: " + www.error);
            }
        }
    }

4.读取Resources文件夹下的json文件

//读取Resources下的json文件
    public void ReadJson(string fileName)
    {
        //获得Json字符串
        string json = "";
        TextAsset text = Resources.Load<TextAsset>("levels/" + fileName);
        json = text.text;
        if (string.IsNullOrEmpty(json))
        {
            json = "";
            Debug.LogError(fileName + "...json is null or empty!");
        }
        Debug.Log(json);
 
        JObject jsonData = JObject.Parse(json);
        JToken jToken = jsonData["level"];
        JArray ja = JArray.Parse(jsonData["level"]["time"].ToString());
 
        le = new LevelEntity();
        le._floorCount = int.Parse(jToken["floorCount"].ToString());
        le._maxNum = int.Parse(jToken["maxNum"].ToString());
        le._left = int.Parse(jToken["left"].ToString());
        le._right = int.Parse(jToken["right"].ToString());
        for (int i = 0; i < ja.Count; i++)
        {
            string str1 = ja[i].ToString().Replace("{", "").Replace("}", "");
            string[] str2 = str1.Split(':');
            le._time.Add(float.Parse(str2[1]));
        }
    }

5.newtonsoft.Dll下载

去下载
 

6.实体类转json 存本地

//存本地--单个
        string str = JsonUtility.ToJson(entity, true);
        string filePath = Application.streamingAssetsPath + "/sbHaveList.json";
        using (StreamWriter sw = new StreamWriter(filePath))
        {
            sw.WriteLine(str);
            sw.Close();
            sw.Dispose();
        }
