1) 引入json库

require("src/cocos/cocos2d/json")

2) 使用json

-- table转json
local jsonData = json.encode(tableData)
-- json转table
local testTable = json.decode(jsonData)

2. 数据持久化

1) 保存json数据

local tableData = json.encode(TABLE_DATA)
local file = io.open(SAVE_PATH,"wb")
file:write(tableData)
io.close(file)

2) 读取json数据

 local file = io.open(SAVE_PATH, "rb")
 local readjson= file:read("*a")  --read all
 file:close()
 local tableData = json.decode(readjson)
