nil、null与ngx.null

发现一个nginx LUA开发Web App的框架

nginx是个好东西， nginx的openrtsy发行版本更是个好东西。

今天又发现个好东西：Moochine

MOOCHINE - 一个简单的轻量级的web framework，基于ngx_OpenResty(ngx_lua,ttp://openresty.org) 做的框架，

使用例子 https://github.com/appwilldev/moochine-demo

项目地址：https://github.com/appwilldev/moochine

可以让我们构建WebApp 更加的简单，具体使用方法请看具体的 moochine-demo
