代码高亮显示
此处gitbook中代码高亮的插件用的是prism
下面列出常见的几种代码的代码高亮效果。

# HTTP简介
`HTTP`=`Hyper Text Transfer Protocol`=`超文本传输协议`
HTTP的总体思路是：
* 客户端：向服务器发送一个`请求`=`Request`，请求头包含请求的方法、URI、协议版本、以及包含请求修饰符、客户信息和内容的类似于MIME的消息结构。
* `服务器`：以一个状态行作出`响应`=`Response`，相应的内容包括消息协议的版本，成功或者错误编码加上包含服务器信息、实体元信息以及可能的实体内容。
简而言之就是一个你问我答的协议：
* 客户端Client 问=`请求`=`Request`
* 服务器Server 答=`响应`=`Response`
关于HTTP的相关的详细知识，或许很多人不是很熟悉。
但是：
- 作为普通电脑用户的你，经常用`浏览器`（`IE`/`Chrome`/`Firefox`等）去浏览网页时
- 作为程序开发，用网络库去调用服务器后台提供的接口时
其实内部都用到了HTTP的技术。
