固件版本

• 固件名称：如 LuatOS-SoC_V0006_AIR101_LVGL.soc
• 使用设备：如 Air101开发板
• 使用功能：序列化为json字符串 参照demo 中json例子

描述一下这个问题

序列化后的json字符串的键的次序与table中元素的次序不一样.比如
local t = {
a = 1,
b = "abc",
c = {
1,2,3,4
},
d = {
x = false,
j = 111111
},
aaaa = 6666,
}
则序列化json字符串为 {"aaaa":6666,"b":"abc","a":1,"d":{"x":false,"j":111111},"c":[1,2,3,4]}

最小复现工程

-- LuaTools需要PROJECT和VERSION这两个信息
PROJECT = "jsondemo"
VERSION = "1.0.0"

-- 引入必要的库文件(lua编写), 内部库不需要require
local sys = require "sys"

log.info("main", "json demo")
print(json.null)

local t = {
a = 1,
b = "abc",
c = {
1,2,3,4
},
d = {
x = false,
j = 111111
},
aaaa = 6666,
}

local s = json.encode(t)

local st = json.decode(s)

print(s)
print(st.a,st.b,st.d.x)

-- 用户代码已结束---------------------------------------------
-- 结尾总是这一句
sys.run()
-- sys.run()之后后面不要加任何语句!!!!!
