解析JSON

local sjson = require "sjson"
 local sampleJson = [[{"age":"23","testArray":{"array":[8,9,11,14,25]},"Himi":"himigame.com"}]];
--解析json字串
local data = sjson.decode(sampleJson);
--列印json字串中的age欄位
print(data["age"]);
--列印陣列中的第一個值(lua預設是從0開始計數)
print(data["testArray"]["array"][1]);

編碼JSON

local sjson = require "sjson"
 local retTable = {};    --最終產生json的表
--順序數值
local intDatas = {};
 intDatas[1] = 100;
 intDatas[2] = "100";
--陣列
local aryDatas = {};
 aryDatas[1] = {};
 aryDatas[1]["鍵11"] = "值11";
 aryDatas[1]["鍵12"] = "值12";
 aryDatas[2] = {};
 aryDatas[2]["鍵21"] = "值21";
 aryDatas[2]["鍵22"] = "值22";
--對Table賦值
retTable["鍵1"] = "值1";
 retTable[2] = 123;
 retTable["int_datas"] = intDatas;
 retTable["aryDatas"] = aryDatas;
--將表資料編碼成json字串
local jsonStr = sjson.encode(retTable);
 print(jsonStr);
--結果是:{"int_datas":[100,"100"],"2":123,"鍵1":"值1","aryDatas":[{"鍵12":"值12","鍵11":"值11"},{"鍵21":"值21","鍵22":"值22"}]}
