c++ web framework 很少
随着 c++ 热度升温，c++ 在人工智能自然语言处理加快应用。
最近一款国产 paozhu c++ web framework 问世
写业务速度跟脚步语言一样速度，主要是写业务代码优雅，方便后面附 CURD 例子

自带 json 内置 decode encode 支持，支持标准 json 输出，支持 emoji 编码
支持多域名网站
支持多域名 ssl 服务端
支持 http1.1、http2 协议
支持 websocket 服务端，
框架自带 websocket 推送，支持定时推送到 webscoket 客户端
支持同步 httpclient get post
框架自带 ORM, 使用链接池方式，目前支持 mysql
框架自带线程池，和用户代码运行的线程池
框架使用 asio 自带的协程
框架特色是 I/O 使用协程池运行使用线程池
框架支持普通文件 gzip br
框架解析 URL 和 POST, 解析结果类似 PHP GET POST 方式获取内容
集成 sendmail
生成二维码 (qrcode), 需要 gd、qrencode 库

目前支持mac linux
具体可以看官方github
