请求（网址访问，提交数据等等） request
响应（回复页面，回复数据等等） response
web框架的本质及自定义web框架我们可以这样理解：所有的Web应用本质上就是一个socket服务端，而用户的浏览器就是一个socket客户端，基于请求做出响应，客户都先请求，服务端做出对应的响应，按照http协议的请求协议发送请求，服务端按照http协议的响应协议来响应请求，这样的网络通信，我们就可以自己实现Web框架了。
通过对socket的学习，我们知道网络通信，我们完全可以自己写了，因为socket就是做网络通信用的，下面我们就基于socket来自己实现一个web框架，写一个web服务端，让浏览器来请求，并通过自己的服务端把页面返回给浏览器，浏览器渲染出我们想要的效果。在后面的学习中，大家提前准备一些文件：
