c++ web framework很少，
隨著c++ 熱度升溫，c++ 在人工智能 自然語言處理 加快應用，
最近一款國產 c++ web framework 問世
寫業務速度跟腳步語言一樣速度
-
自帶json內置支持
-
支持多域名網站
-
支持多域名ssl 服務端
-
支持http1.1、http2協議
-
支持websocket服務端，
-
框架自帶websocket推送，支持定時推送到webscoket客戶端
-
支持同步httpclient get post
-
框架自帶ORM,使用鏈接池方式，目前支持mysql
-
框架自帶執行緒池，和用戶代碼運行的執行緒池
-
框架使用asio自帶的協程
-
框架特色是I/O 使用協程池 運行使用執行緒池
-
框架支持普通檔案gzip br
-
框架決議URL和POST,決議結果類似PHP GET POST方式獲取內容
-
集成sendmail
-
生成二維碼(qrcode),需要gd、qrencode庫
目前支持mac linux

主要是寫業務代碼優雅，方便 CURD例子

#include <chrono>

#include "testcurd.h"
