1、http请求跳转
[root@n86 bin]
# curl -I -L 10.50.200.32
HTTP
/1
.1 302 FOUND
Server: nginx
/1
.6.2
Date: Fri, 25 Dec 2015 02:43:18 GMT
Content-Type: text
/html
; charset=utf-8
Connection: keep-alive
X-Frame-Options: SAMEORIGIN
Location: http:
//10
.50.200.32
/charade/
HTTP
/1
.1 200 OK
Server: nginx
/1
.6.2
Date: Fri, 25 Dec 2015 02:43:18 GMT
Content-Type: text
/html
; charset=utf-8
Connection: keep-alive
Vary: Cookie
X-Frame-Options: SAMEORIGIN
Set-Cookie: csrftoken=5dY37iQgcjQnYh1jZdrxptyIkTfUh3Rr; expires=Fri, 23-Dec-2016 02:43:18 GMT; Max-Age=31449600; Path=/
2、https请求GET和PUT
使用证书 curl -s --cacert ca.crt
忽略证书 curl -s -k
curl -s -k -u
"user:passwd"
-H
"Content-type: application/xml"
-X GET https:
//abc
.com
/api/vms
curl -s -k \
-u
"user:passwd"
\
-H
"Content-type: application/xml"
\
-d "
<vm>
<name>test03<
/name
>
<cluster><name>Host-Only<
/name
><
/cluster
>
<template><name>centos6u5x64-small-01<
/name
><
/template
>
<
/vm
>
" \
"https://e01.test/api/vms"
3、http状态
hostname
=www.qq.com
1）得到http status
[root@svr200-22 ~]
# curl -o /dev/null -s -w %{http_code} ${hostname}
200
2）得到详细的 http headers 信息
[root@svr200-22 ~]
# curl -o /dev/null -v http://${hostname}
* About to connect() to www.qq.com port 80 (
#0)
* Trying 14.17.32.211... connected
* Connected to www.qq.com (14.17.32.211) port 80 (
#0)

3）指定一个目标主机IP（此处以从dns中得到的一个解析结果为例），得到 http headers 信息：
[root@svr200-22 ~]
# nslookup ${hostname} |grep Address |grep -v "#53$" |cut -d " " -f2 |head -n 1 |xargs -i curl -I -H "Host:${hostname}" http://{}/

5）得到请求响应时间
[root@svr200-22 ~]
# curl -o /dev/null -s -w "time_connect: %{time_connect}\ntime_starttransfer: %{time_starttransfer}\ntime_total: %{time_total}\n" ${hostname}
time_connect: 0.046
time_starttransfer: 0.078
time_total: 0.078
4、curl GET 请求中传递参数为 json 格式，且需要传递变量进去时，如何处理转义的问题
有3种方式来处理：
1）转义参数中的： {} [] "
curl -s \
--unix-socket
/var/run/docker
.sock \
"http:/services?filters=\{\"name\":\[\"${service_name}\"\]\}"
\
|jq
'.'
2）转义参数中的： url外层不用
""
包含，内层使用
''
来限制。
curl -s \
--unix-socket
/var/run/docker
.sock \
http:
/services
?filters=
'\{"name":\["'
${service_name}
'"\]\}'
\
|jq
'.'
3）使用 curl -g 参数来允许 URL 中使用 {}[] 而不用转义
-g, --globoff
This option switches off the
"URL globbing parser"
. When you
set
this option, you can specify URLs that contain the letters {}[] without having them being inter‐
preted by curl itself. Note that these letters are not normal legal URL contents but they should be encoded according to the URI standard.
实例
~]$ curl
"127.0.0.1:10001/services?filters=\{\"name\":\[\"${service_name}\"\]\}"
GET
/services
?filters={
"name"
:[
"t001"
]} HTTP
/1
.1
~]$ curl 127.0.0.1:10001
/services
?filters=
'\{"name":\["'
${service_name}
'"\]\}'
GET
/services
?filters={
"name"
:[
"t001"
]} HTTP
/1
.1
~]$ curl -g 127.0.0.1:10001
/services
?filters=
'{"name":["'
${service_name}
'"]}'
GET
/services
?filters={
"name"
:[
"t001"
]} HTTP
/1
.1
