已解决，原来是序列化的问题。

恩，是有点问题。先自己用 pairs 来输出一下吧，回头我看看 ngx.say 部分。
你可以先这样输出：
for k in pairs(lua_table) do
v = lua_table[k]
if type(v) == "table" then
for k2 in pairs(lua_table[k]) do
ngx.say(k, k2, lua_table[k][k2])
end
else
ngx.say(k, lua_table[k])
end
end

访问t可输出bar，而访问t2却出现如下：
[error] 1832#0: *3 lua entry thread aborted: runtime error: [string "content_by_lua"]:6: bad argument #1 to 'say' (non-array table found)
stack traceback:
coroutine 0:
[C]: in function 'say'
[string "content_by_lua"]:6: in function <[string "content_by_lua"]:1>
请问如何解决？
