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

新款 c++ web framework 支持orm http/2

主要是写业务代码优雅，方便 CURD例子

#include "orm.h"
#include <chrono>
#include <thread>
#include "md5.h"
#include "func.h"
#include "httppeer.h"
#include "testcurd.h"
namespace http
