asdemotest.lua

function info(rec)
    local map = map()
    -- must use map = {} !!!  else return null !!!
    -- local map = {}
    map["version"] = "20210929"
    return map
end

function info2(rec,params)
    local map = map()
    map["params"] = params
    return map
end

使用amc上传lua 或者 使用 AQL 注册脚本

使用 AQL命令 直接覆盖更新 
REGISTER MODULE 'xxx.lua'
通过 SHOW MODULES 查看更新前后 hash
