Centos 下Curl 常用GET/POST用法

一.获取域名头部信息

[root@localhost root]# curl -I "www.baidu.com"
HTTP/1.1 200 OK
Accept-Ranges: bytes
Cache-Control: private, no-cache, no-store, proxy-revalidate, no-transform
Connection: Keep-Alive
Content-Length: 277
Content-Type: text/html

Last-Modified: Mon, 13 Jun 2016 02:50:13 GMT
Pragma: no-cache
Server: bfe/1.0.8.18

二.直接GET请求

curl www.baidu.com

注意：当url中有&等特殊字符时，需要将整个url用双引号括起来

三.POST请求

1.有两种方式，第一种是参数方式

curl -d "args" "protocol://address:port/url"

2.json格式参数

curl -H "Content-Type:application/json" -X POST --data (json.data) URL

四.指定自定义header值进行请求

curl -H "mykey:15445444ad45454" URL
