* **前言**
本项目是基于C++线程池的轻量级Web并发服务器,事件处理模式采用Reactor模式，主线程只负责监听文件描述符是否有事件发生，读写数据、接收新的连接、以及处理客户请求均在工作线程中实现；使用半同步/半异步模式，每个线程（主线程和工作线程）都通过一个epoll维护自己的事件循环，它们各自独立地监听不同事件。使用C++ 11的atomic原子变量来同步线程访问从而避免同步错误；使用STL的优先队列作为定时器容器来回收非活动长连接。本项目的具体设计思路可以参照本人的知乎文章[C++网络编程入门：轻量级Web并发服务器开发](https://zhuanlan.zhihu.com/p/109905285)，纯属抛砖引玉，欢迎大佬们批评指正。
* **运行环境**
(1).系统：Ubuntu16.04;
(2).语言：C++ 11及以上版本;
* **支持功能**
(1).支持Get请求;
(2).支持长连接/短连接;
(3).支持ipv4/ipv6;(4).支持tcp;(5).支持请求静态内容(6).支持并发请求
* **开始运行**
(1).下载程序;
`git clone git@github.com:Buerzhu/TinyWeb.git`
(2).打开新终端，指定ip地址和端口运行服务器程序：
`cd ~/TinyWeb/Server/Debug`
`./server 127.0.0.1 12345`
(3).打开新终端，指定ip地址、端口、客户连接数运行压力测试程序：
`cd ~/TinyWeb/Client/Debug`
`./client 127.0.0.1 12345 1000`
================================================
FILE: Server/Codes/README.md
================================================
* **web_thread.h**
(1). 定义了webthread类;
(2). 该类是主线程与子线程通信的媒介，本程序对于每个子线程建立对应的wedthread全局对象,主线程通过该对象来与子线程通信，子线程通过该对象接收来自主线程的消息，并运行该对象的work()函数来处理主线程消息和用户的http请求。
* **http_conn.h**
(1).定义了http_conn类和util_timer类;
(2).http_conn类是用于处理http请求和作出http应答的一个类，本程序对于每个新连接的用户都分配一个http_conn对象用于处理http请求;
(3).util_timer类是定时器类，本程序对于每个新连接的用户都分配一个定时器对象，并设置该定时器的超时时间，如果长连接用户在超时时间内都处于非活动状态则关闭用户连接，如果用户在超时时间到达之前重新活动则延长超时时间。
* **web_function.h**
(1).该文件用于定义全局变量和常量，包括线程数、当前总用户数、读写缓冲区大小等，如果要支持更多的并发用户请求，应该修改该文件中定义的这些常量;
(2).该文件还提供了一些通用的基本功能函数，例如显示当前时区时间的函数，显示用户ip地址的函数等;
* **main.cpp**
(1). 程序运行入口
(2). 主线程只负责监听文件描述符是否有事件发生而不处理面向用户的业务逻辑(Reactor模式);
* **server.pro**
(1). 该文件是qtcreator关于qmake的工程文件，qt通过该文件来生成Makefile文件。
