HTTPS知识
HTTPS（全称Hyper Text Transfer Protocol over Secure Socket Layer），是以安全为目标的HTTP通道，简单讲是HTTP的安全版。即HTTP下加入SSL层，HTTPS的安全基础是SSL，加密的详细内容就需要SSL。
它是一个URI scheme（抽象标识符体系），句法类同http:体系。用于安全的HTTP数据传输。
https:URL表明它使用了HTTP，但HTTPS存在不同于HTTP的默认端口及一个加密/身份验证层（在HTTP与TCP之间）。

HTTPS和HTTP的区别主要为以下四点
1、https协议需要到ca申请证书，一般免费证书很少，需要交费。
2、http是超文本传输协议，信息是明文传输，https 则是具有安全性的ssl加密传输协议。
3、http和https使用的是完全不同的连接方式，用的端口也不一样，前者是80，后者是443。
4、http的连接很简单，是无状态的；HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议，比http协议安全。
