一、6-8作業總結 （1）第六次作業：第一次作業分了兩個題，一個電信1題目非常長，給出了類圖，類很多工作量很大。還一個題以容器類為例展現了介面，多態的用處和效果，題目給出的提示非常多，按照題目來，再加上一些測試代碼，可以運用equals類實現。 （2）第七次作業：第二次作業分了三個小題，第一個還是電 ...
c++ web framework很少，
隨著c++ 熱度升溫，c++ 在人工智慧 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
-
支持多功能變數名稱網站
-
支持多功能變數名稱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
-
框架自帶線程池，和用戶代碼運行的線程池
-
框架使用asio自帶的協程
-
框架特色是I/O 使用協程池 運行使用線程池
-
框架支持普通文件gzip br
-
框架解析URL和POST,解析結果類似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
具體可以看官方github
