WebServer(Httpancake): self-learning project

Introduction

A simple C++ webserver for responsing HTTP-request(s). It's a self-learning project which draws heavily on the design of the following projects:

• muduo
• WebServer

Different from these projects, this webserver is implemented based on C++11 standard library (e.g., std::thread, std::mutex).

Environment

• Ubuntu 20.04
• gcc 9.3.0 [g++]

Usage

【STILL DIRTY NOW】 Hard-coding the server-address-port and source path, make it and run:

./build/bin/httpancake

Technical Points

• Configuration interface
• Reactor server model
• EventLoop threadpool [One-loop-per-thread]
• Simple async log system
• HTTP-request parsing & responsing [GET]
• Use Timers to shutdown idle connections
• MySQL connection-pool

Test Results
