在游戏开发过程中经常使用Json文件作为存储本地数据的文件，这里介绍下cocos2d-x lua 3.6中如何使用Json文件。

思路：

将Json文件当作文本导入到程序中通过引擎提供的Json库解析Json数据文件为table

代码

local str = cc.fileUtils:getInstance():getStringFromfile(config_file_name)    local data = Json.decode(str)    self.data_ = data    for k,val in ipairs(data) do        table.foreach(val,function(i,v) print (i,v) end)    end

读取的Json文件

[    {"ID":1,"name":"dici","Json":"dici.ExportJson","pList":"dici0.pList","png":"dici0.png"},{"ID":2,"name":"ForeAnimation","Json":"ForeAnimation.ExportJson","pList":"ForeAnimation0.pList","png":"ForeAnimation0.png"}]

附加一段自动读取cocos的骨骼动画文件为Json数据文件的python脚本.这个脚本的功能是自动查找当前文件夹，以及其子目录中的骨骼动画文件，并按照指定的格式在当前目录导出Json文件。

#Coding=utf-8import os,sys,reimport Jsonfile_path = []def getnameList(dir,wildcard,recursion):    exts = wildcard.split(" ")    files = os.Listdir(dir)    for name in files:        fullname = os.path.join(dir,name)        if os.path.isdir(fullname) & recursion:            getnameList(fullname,recursion)        else:            for ext in exts:                if(name.endswith(ext)):                    file_path.append(fullname)                    #print(fullname)                    breakclass AnimationData:    ID = -1    name = ""    image_name = ""    pList_name = ""    Json_name = ""    def __init__(self,ID,name,image_name,pList_name,Json_name):        self.ID = ID        self.image_name = image_name        self.pList_name = pList_name        self.Json_name = Json_name        self.name = name    def getDictionary(self):        ret = {}        ret["ID"] = self.ID        ret["name"] = self.name        ret["image"] = self.image_name        ret["pList"] = self.pList_name        ret["Json"] = self.Json_name        return retdef run():    getnameList(sys.path[0],".ExportJson",1)    file_name_List = file_path    resList = []    ID = 1    for file_name in file_name_List:        a = file_name.find(".ExportJson")        if a<>-1:            Json_name = file_name.split("\")[-1]            #print Json_name            name = Json_name.split(".")[0]            #print name            image_name = ("%s0.png")%(name)            pList_name = ("%s0.pList")%(name)            res = AnimationData(ID,Json_name)            resList.append(res)            ID += 1    print ID    l_out = []    for ani in resList:        l_out.append(ani.getDictionary())    print l_out    encode_Json = Json.dumps(l_out)    print encode_Json    abs_path = os.path.abspath(sys.argv[0])    abs_path_List = abs_path.split("\")    length = len(abs_path_List)    out_path = ""    for index,value in enumerate(abs_path_List):        if index >= length - 1:            break        if index == 0:            out_path = ("%s\"%(value))        else:            out_path = ("%s%s\"%(out_path,value))    out_path = ("%s%s"%(out_path,"AnimationConfig.Json"))    print out_path    f = open(out_path,"w")    f.write(encode_Json)    f.close()if __name__ == "__main__":    run()
