因为项目需要请求参数进行treemap自然排序进行参数校验，前端很好搞 我这做在openresty上的lua校验就比较麻烦了，也没搜到解决方案，就自己尝试弄了下
-- 类Treemap自然排序函数
local function list_sort(a, b)
local a_len = string.len(a)
local b_len = string.len(b)
local max_len = a_len
if b_len > a_len then
max_len = b_len
end
for i = 1, max_len do
if string.len(a) < i then
if a_len > b_len then
return false
else
return true
end
end
if string.len(b) < i then
if a_len > b_len then
return false
else
return true
end
end
local a_byte = string.byte(a, i)
local b_byte = string.byte(b, i)
if a_byte == b_byte then
end
if a_byte > b_byte then
return false
end
if a_byte < b_byte then
return true
end
end
end
param_key_list = { "province","city","provinceCode","areaCode", "integrateStoreId", "detailAddress", "appKey", "cityCode","receiveName", "area", "subShopName" }
table.sort(param_key_list, list_sort)
for i, k in ipairs(param_key_list) do
print(k)
end
目前在项目使用没遇到问题
