关于数据传递 json

关于这几种语言的json 操作

Lua

local cjson2 = require "cjson"

local lua_object = {

    ["name"] = "Jiang",

    ["age"] = 24,

    ["addr"] = "BeiJing",

    ["email"] = "1569989xxxx@126.com",

    ["tel"] = "1569989xxxx"

}

local tmp = cjson2.encode(lua_object)

print(obj["age"])

function Utils:ParseJson( json )

    if not json or #json < 2 then--两端{}

        return

    end

    local err,data = pcall(function(json)return cjson.decode(json)end,json);

    if err == false then

        data = nil;

    end

    return data;

end

C# JsonUtility

class Person {

    public int age;

    public string name;

}

private void Awake(){

     Person p = new Person();

     p.age = 20;

     p.name = "zhang san";

     string json = JsonUtility.ToJson(p, true);

     Debug.Log(json);

     var re = JsonUtility.FromJson<Person>(json);

     Debug.Log(re.age.ToString() + "-------------------");

}  

//如果json的key比对象的字段多也可以正常解析 
//string json = "{\"addr\": \"BeiJing\",\"tel\": \"1569989xxxx\",\"age\": 24,\"name\": \"Jiang\",\"email\": \"1569989xxxx@126.com\"}";

C# Newtonsoft.Json 上面的如果lua 加了个字段给java，在C#有使用能解析(主要是要申明一个类，其实如果需求在这里变了，改C#不能热更，策划应该能接受)

Newtonsoft是比较原始的字典，不用声明一个类

        Dictionary<string, object> dic = new Dictionary<string, object>();

        dic["age"] = 25;

        dic["name"] = "张三";

        var item = JsonConvert.SerializeObject(dic);

        Debug.Log(item);

        var tmp = JsonConvert.DeserializeObject<Dictionary<string, object>>(item);

        Debug.Log(tmp["name"].ToString());

Java In Android import org.json.JSONObject

        try{

            JSONObject jsonObject1 = new JSONObject();

            jsonObject1.put("name","zhangsan");

            jsonObject1.put("age",12);

            String tmp = jsonObject1.toString();

            Log.i("LogLogLog",tmp);

            JSONObject js2 = new JSONObject(tmp);

            String name = js2.getString("name");

            Log.i("namenamenamename",name);

        }

        catch (Exception e) {

        }

JSONObject jsonObject = new JSONObject(str);

Iterator<String> it = jsonObject.keys();

while(it.hasNext()){

// 获得key

String key = it.next();

String value = jsonObject.getString(key);

System.out.println("key: "+key+",value:"+value);}

Object-C In iOS

+ (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString

{

    if (jsonString == nil) {

        return nil;

    }

    NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

    NSError *err;

    NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData

                                                        options:NSJSONReadingMutableContainers

                                                          error:&err];

    if(err)

    {

        NSLog(@"json解析失败：%@",err);

        return nil;

    }

    return dic;

}

+ (NSString *)jsonStringWithDict:(NSDictionary *)dict {

    NSError *error;

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&error];

    NSString *jsonString;

    if (!jsonData) {

        NSLog(@"%@",error);

    }else{

        jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding];

    }

    return jsonString;

}

这样再也不怕用户取一些怪名字了。

在C#编辑器中直接书写json

        string json = @"{""succ"":true,""content"":""hah""}";

        Dictionary<string, object> jDic = MiniJSON.Json.Deserialize(json) as Dictionary<string, object>;

        Debug.Log(jDic["succ"]);

        Debug.Log(jDic["content"]);

Java 中编写

String json = "{\"succ\":true,\"content\":\"hah\"}";

Log.e("json",json);

OC中编写

NSString  *json = @"{\"succ\":true,\"content\":\"hah\"}"

　　在Unity 中使用Json 各种的复杂的类型都是支持的不支持字典类型 Dictionary<>

using System;

using System.Collections;

using System.Collections.Generic;

using System.Runtime.Serialization;

using System.Web;

using UnityEngine;

using UnityEngine.Networking;

public class LearnSharp : MonoBehaviour

{

    // Start is called before the first frame update

    void Start()

    {

        string json = @"{

                              ""d"": ""dfff"",

                              ""album"": {

                                          ""cc"": ""cc"",

                                          ""name"": ""The Dark Side of the Moon"",

                                          ""artist"": ""Pink Floyd"",

                                          ""year"": 1973,

                                          ""tracks"": [

                                              ""Speak To Me"",

                                              ""Breathe"",

                                              ""On The Run""

                                          ],

                                          ""tt"": ""tt"",

                                          ""tracksOb"": [{

                                                          ""trackOb"": ""11"",

                                                           ""trackObddf"": ""11""

                                                       },

                                                      {

                                                          ""trackOb"": ""22""

                                                      }

                                                      ],

                                          ""bb"": ""bb""

                                          }

                       }";

        var obj = GetData2<Root>(json);

        Debug.Log(obj.ToString());

    }

    public static T GetData2<T>(string text) where T : class

    {

        //JsonData table = AnalysisJson.Analy<JsonData>(text);

        T t = JsonUtility.FromJson<T>(text);

        return t;

    }

}

[Serializable]

public class TracksObItem

{

    public string trackOb;

    public string newVar;

    public override string ToString()

    {

        string name = "";

        return $"{trackOb}   {trackOb}  ";

    }

    public void OnDeserialization(object sender)

    {

        Debug.Log("OnDeserialization");

    }

}

[Serializable]

public class Album

{

    public string cc;

    public string name;

    public string artist;

    public int year;

    public List<string> tracks;

    public string tt;

    public List<TracksObItem> tracksOb;

    public string bb;

}

[Serializable]

public class Root

{

    public string d;

    public Album album;

    public override string ToString()

    {

        string name = "";

        return $"{d}   {album.name}  {album.tracks[1]}    {album.tracksOb[1].trackOb} {album.tracksOb[1].newVar}";

    }

}

　　这个是例子，感觉功能很强大。数组多层嵌套都支持。
