json - lua json解析变量

Question

是否可以使用变量来解析 json 的路径？像这样？

json = require('json')
base={magali={pass='melancia'}}

--~ local oo = json.decode( readAll("../json/base.json") )
local oo = base
user = 'magali'
print("oo[" .. oo.magali.pass .. "]") -- work
print("oo[" .. oo.user.pass .. "]") -- does not work! How do this?

错误：

lua53: example.lua:34: attempt to index a nil value (field 'user')
stack traceback:
    example.lua:34: in main chunk
    [C]: in ?
