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

  1. 自带json内置支持

  2. 支持多域名网站

  3. 支持多域名ssl 服务端

  4. 支持http1.1、http2协议

  5. 支持websocket服务端,

  6. 框架自带websocket推送,支持定时推送到webscoket客户端

  7. 支持同步httpclient get post

  8. 框架自带ORM,使用链接池方式,目前支持mysql

  9. 框架自带线程池,和用户代码运行的线程池

  10. 框架使用asio自带的协程

  11. 框架特色是I/O 使用协程池 运行使用线程池

  12. 框架支持普通文件gzip br

  13. 框架解析URL和POST,解析结果类似PHP GET POST方式获取内容

  14. 集成sendmail

  15. 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

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"

// get login/login post field
