Drogon is a C++11-based HTTP application framework. Drogon can be used to easily build various types of web application server programs using C++. Drogon is the name of a dragon in the American TV series "Game of Thrones" that I really like.
Drogon's main application platform is Linux. For debugging purposes, it also supports Mac OS. There is no plan to support Windows. Its main features are as follows:
- The network layer uses a NIO framework based on epoll (poll under MacOS) to provide high-concurrency, high-performance network IO;
- Full asynchronous programming mode;
- Support Http1.0/1.1 (server side and client side);
- Based on template, a simple reflection mechanism is implemented to completely decouple the main program framework, controller and view.
- Support for cookies and built-in sessions;
- Support back-end rendering, the controller generates the data to the view to generate the Html page, the view is described by a "JSP-like" CSP file, the C++ code is embedded into the Html page by the CSP tag, and the drogon command-line tool automatically generates the C++ code file for compilation;
- Support view page dynamic loading (dynamic compilation and loading at runtime);
- Very convenient and flexible path to controller handler mapping scheme;
- Support filter chain to facilitate the execution of unified logic (such as login verification, Http Method constraint verification, etc.) before the controller;
- Support https (based on OpenSSL);
- Support websocket (server side);
- Support Json format request and response;
- Support file download and upload;
- Support gzip compression transmission;
- Provides a lightweight command line tool, drogon_ctl, to simplify the creation of various classes in Drogon and the generation of view code;
