Unity 加载UTF-8 *.Json文件,调用JsonMapper.ToObject异常
发表于2018-08-09
*.Json文件使用UTF-8文件不保存格式的话被LitJson中的JsonMapper.ToObject调用报异常：
JsonException:Invalidcharacter'?'ininputstring
LitJson.Lexer.NextToken()
LitJson.JsonReader.ReadToken()
LitJson.JsonReader.Read()
LitJson.JsonMapper.ReadValue(LitJson.WrapperFactoryfactory,LitJson.JsonReaderreader)
LitJson.JsonMapper.ToWrapper(LitJson.WrapperFactoryfactory,System.Stringjson)
LitJson.JsonMapper.ToObject(System.Stringjson)
有用UTF-8保存文件有4个无用字节i.e.
using UnityEngine;
using System.Collections;
using LitJson;
using System.Text;
public class GetVersion : MonoBehaviour ｛
string CallFun = "";
string filepath = "";
private string _tipMessage = "";
[SerializeField]
private UISprite _loginBt;
private Color _color=new Color(1,1,1,0.5f);
void Start () ｛
InitWWWJson("file://"+Application.dataPath + "/StreamingAssets/MusesMobileAppVersion.json", "");
｝
public void InitWWWJson(string Path, string CallFun)
｛
this.CallFun = CallFun;
filepath = Path;
WWW www = new WWW(filepath);
StartCoroutine(LinkNetWork(www));
｝
IEnumerator LinkNetWork(WWW www)
｛
yield return www;
if (www.error == null)
｛
//ReadJson(www.text);直接使用抛异常
string jsonData = System.Text.Encoding.UTF8.GetString(www.bytes, 3, www.bytes.Length - 3); // Skip thr first 3 bytes (i.e. the UTF8 BOM)
ReadJson(jsonData);
｝
｝
private void ReadJson(string versionMessage)
｛
Debug.Log( versionMessage);
JsonData _json = JsonMapper.ToObject(versionMessage)["Diet"];
string version= _json["version"].ToString();
Debug.Log("版本号" + version);
Debug.Log("name:" + _json["name"].ToString());
if (version != Application.version)
｛
_tipMessage = _json["msg"].ToString();
Messenger.Broadcast<string>("MessageBoxError", _tipMessage);
if (_json["enabled"].ToString() != "true")
｛
_loginBt.color = _color;
_loginBt.transform.GetComponent<BoxCollider>().enabled = false;
｝
｝
｝
｝
JSON文件
｛
"Diet": ｛
"name": "91小二",
"version": "1.1.2",
"enabled":"true",
"msg":"检测到新版本，请更新",
"updateTime": "20160628"
｝
｝
这个是一个简单的检测版本是否需要更新并提升，把*.json放到服务器上就可以了
