http cURL 响应 header 查看

curl 查看 HTTP Header 响应头信息,可参见米扑博客:curl 查看 HTTP Header 响应头信息

1、curl -I 查看HTTP 响应头信息

curl -I













yg-mac:~ homer$ curl -I

HTTP/1.1 200 OK

Server: nginx

Date: Thu, 31 May 2018 03:51:08 GMT

Content-Type: text/html; charset=UTF-8

Connection: keep-alive

Vary: Accept-Encoding

Set-Cookie: PHPSESSID=d4kf789gvurb10p7g5pcqd80o6; path=/

Expires: Thu, 19 Nov 1981 08:52:00 GMT

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0

Pragma: no-cache

Vary: proxys-bj


2、HTTP 响应头的信息

1) HTTP 返回码

  • 1xx:client的请求server已经接收,正在处理
  • 2xx:成功  表示 client请求,server端已经接收、理解并处理
  • 3xx:client 请求被重定向其他的server【其他的URL】
  • 4xx:表示client请求不正确,server不能识别
  • 5xx:server端服务不正常

2) Cache-Control

web 站点对缓存的设置;

  • no-cache:表示server 不允许client 设置缓存;client每次请求都需要请求后端的服务
  • max-age:server设置页面的缓存时间;单位是秒  即:1个小时内此client再访问 用刚才的缓存;不再重复访问后台服务器
  • private must-revalidate

3) Connection

server 是否支持长连接;如果keep-alive 说明web的server 支持长连接。

但是TCP 的长连接是双向的;必须是client和server 都支持长连接;才可以建立长连接。

一般client 【浏览器】都是默认支持长连接;所以只要sever端支持长连接;就可以建立长连接。



3、curl 发送Get/Post 请求

1)get 请求

我们平时用的最多的就是curl 不加任何的参数,其实这样就是get请求;把参数都放在http://xx 后面

curl ""


2)post 请求

curl -d ''

curl -H "Content-Type:application/json" -X POST -d '{"post_data":""}' ''



curl -F 'csl=@/home/xxxx/xxx.csl' -F 'tag=xxx' -F 'category=full' ""


curl HTTP Header

对于"User-Agent", "Cookie", "Host"这类标准的HTTP头部字段,通常会有另外一种设置方法。


  • -A (or --user-agent): 设置 "User-Agent" 字段.
  • -b (or --cookie): 设置 "Cookie" 字段.
  • -e (or --referer): 设置 "Referer" 字段.




$ curl -H "User-Agent: my browser" ""

$ curl -A "my browser" ""

1)with JSON

curl -i -H "Accept: application/json" -H "Content-Type: application/json"


2)with XML

curl -H "Accept: application/xml" -H "Content-Type: application/xml" -X GET



1)For posting data

curl --data "param1=value1&param2=value2"


2)For file upload

curl --form "fileupload=@filename.txt"


3)RESTful HTTP Post

curl -X POST -d @filename


4)For logging into a site (auth)

curl -d "username=admin&password=admin&submit=Login" --dump-header headers curl -L -b headers
