GET和POST请求区别
1. POST请求的请求参数在请求实体内容中,GET请求的请求参数存放在URL中。
2. POST请求比GET请求安全?(都不安全)
3. GET请求的URL参数长度有限(不超过2K),POST没有长度限制
4. GET请求一般做查询(有缓存),POST请求一般做添加/删除/修改(无缓存)
5. Django服务器GET/POST请求为什么接受参数方式都一样?
因为他们都是QueryDict对象(django.http.request)
GET请求方式
1. <form method="get">
2. 浏览器地址栏直接访问
3. <a href="/student/">超链接</a>
4. window.location.href="/student/"
POST请求方式
1. <form method="post">
HTTP特性
1. HTTP1.1版本后支持长连接
2. 单向性协议(必须先有请求后有响应)
3. 无状态的协议
Cookie:客户端相关
Session:服务器相关
