新款 c++ web framework 支持orm http/2
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 c++ web framework 问世
写业务速度跟脚步语言一样速度
-
自带json内置支持
-
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
