概述
HTTP报文分为请求报文和响应报文。
常见的请求报文有两种GET方式和POST 方式
区别
GET方式会把数据传在url后面，使用?分割，各个参数之间使用&分割
比如：
https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=1&tn=baidu&wd=%E4%BD%A0%E5%A5%BD&oq=http%25E6%258A%25A5%25E6%2596%2587&rsv_pq=81d8ee2c0000913c&rsv_t=0863vw45F2C66ac%2ByKbOZa%2BDhaEmWiqPbcVqcsE5hyO07Vila1Rjj7VAlz8&rqlang=cn&rsv_dl=tb&rsv_enter=1&rsv_sug3=10&rsv_sug1=12&rsv_sug7=101&rsv_sug2=0&rsv_btype=t&inputT=4163&rsv_sug4=5827
POST 方式会把提交的数据放在HTTP请求的＜request-body＞中。POST 方式的安全性比GET方式高。POST方式理论上对传输的数据量不受限，但GET方式由于URL长短的限制，传递的数据量有限制。
