HTTP概要

HTTP协议（HyperText Transfer Protocol，超文本传输协议）是因特网上应用最为广泛的一种网络传输协议，所有的WWW文件都必须遵守这个标准。

HTTP基于TCP/IP通信协议来传递数据。

HTTP默认端口号为80。

（HTTPS默认端口号为443。）

HTTP请求与响应 

1.get无参请求与响应：

需要注意的点：

（1）get请求传递参数在url中，"?"后，例如【/s?ie=utf-8&wd=get&rsv_sug7=100】

（2）此时实际访问的url为：【https://www.baidu.com/s?ie=utf-8&wd=get&rsv_sug7=100】，是get后的参数与host拼接成的。

（3）严格来说，get是可以带请求体的，不过大部分服务器会忽略（丢弃）get中的请求体；以及违背了安全性原则，会导致缓存机制失效（不安全的数据不会缓存）。详情可见https://my.oschina.net/airship/blog/3081424

（4）服务器在解析有参get与post时，都可以使用getParameter()的方法拿出来（java方法），区别不大。

（5）目前的代码样例是规范的，get没有请求体。

 

3.post有参请求与响应（键值对）

post有参请求(无删减)：

POST /Login/index HTTP/1.1

需要注意的点：

（1）此时post实际访问的网址为【https://www.everyonepiano.cn/Login/index】，是post后的url与host拼接成的；

（2）post的请求参数在body中，也是键值对的形式。

（3）post发送键值对时，一般请求头有：【Content-Type: application/x-www-form-urlencoded;charset=UTF-8】

4.post发送json请求：

post有参请求（json）：

post请求对应的响应：

:status: 400

content-type: application/json;charset=utf-8
x-application-context: application:production

{"message":"用户名或密码错误","status":false,"code":"1039"}

需要注意的点：

（1）这个请求与响应是CSDN的登录页面抓到的

（2）这个请求与响应的格式不太标准，可能是软件问题或缓存问题

（3）总之，发送json请求时，请求头需要有：【content-type: application/json;charset=UTF-8】；如果接收的也是json，也需要有类似的：【accept: application/json, text/plain, */*】；其中*/*表示任意格式的响应都可以接收。

（4）json格式的数据放在请求体中。

（5）响应头中对应的有：【content-type: application/json;charset=utf-8】，json数据在响应体中。

 

5.post接收json响应：

post请求（无删减）：

{"Count":66,"List":[{"ljjz":"","yjkhzdnsyl":"3.5"}]}

需要注意的点：

（1）这个样例的请求是post键值对形式

（2）响应体中的数据是json格式的

（3）请求头中有：【Accept: application/json】，因此可以接收json数据

（4）响应头中使用的是【Content-Type: text/javascript】，不过由于请求头已注明，因此也可以accept这类内容。

 

6.图片的请求与响应

get请求图片：

对应的响应：

:status: 200
server: openresty
date: Thu, 16 Jul 2020 08:50:25 GMT
content-type: image/png
content-length: 3700

accept-ranges: bytes
strict-transport-security: max-age=31536000

PNG

HDR

需要注意的点：

（1）这个请求头与请求体的格式也不太标准，可能是抓包软件的原因。

（2）请求头中有多个cookie键。

（3）请求头中写明accept的是image。

（4）响应头中有：【content-type: image/png】，并且响应体中有图片的字节流；由于是特殊符号，因此无法复制到代码块；以下是字节流截图：

点击抓包工具的Image标签，可以看到图片的样子：

总结

以上便是HTTP常用请求头与请求体的实例。

先记录在这里，之后需要查找时就方便多了。
