安装篇:
我的电脑版本是windows7,64位,对应的curl下载地址如下:
https://curl.haxx.se/download.html
直接找到下面的这个版本:
curl-7.57.0.tar.gz gpg mirror metalink
解压,然后,命令行进入到 curl 目录下:
我的路径为:E:\curl-7.57.0\curl-7.57.0
在该目录下 —— git bash here,或者,wind+r 快捷键 输入cmd ,然后到该目录下
然后,就可以用curl 命令了
例如:
curl 'www.baidu.com'
你会得到如下的信息:
% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed0 0 0 0 0 0 0 0 --:--:-- 0:00:06 --:--:-- 0

首先,学每一种新知识之前,我们都要注重官方文档。在没有资料之前,我们可以先看帮助:、
curl --help
如下:

每一种命令之后都跟了,英文说明,我暂时就不做翻译了。
下面介绍几个常用的命令:
1.查看网页源代码,以 www.oschina.net 为例
curl www.oschina.net
抱歉,我内网受限,总访问超时,只能得到如下信息。
$ curl https://www.oschina.net/% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed0 0 0 0 0 0 0 0 --:--:-- 0:00:15 --:--:-- 0
然后是保存这个文件。
curl -o [文件名] www.sina.com
curl -0 china www.oschina.net
2.只显示头信息 在curl 命令中加上 -i 即可,操作时将网址换成对应自己的,例如:www.oschina.net
$ curl -i -XGET 'localhost:9200/'% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed
100 432 100 432 0 0 27000 0 --:--:-- --:--:-- --:--:-- 27000HTTP/1.1 200 OK
content-type: application/json; charset=UTF-8
content-length: 432{"name" : "5ZS6Wl8","cluster_name" : "elasticsearch","cluster_uuid" : "gY8furXtSsGJr5Nmlv0oNg","version" : {"number" : "6.1.1","build_hash" : "bd92e7f","build_date" : "2017-12-17T20:23:25.338Z","build_snapshot" : false,"lucene_version" : "7.1.0","minimum_wire_compatibility_version" : "5.6.0","minimum_index_compatibility_version" : "5.0.0"},"tagline" : "You Know, for Search"
}
3.显示通信过程(ip地址,端口号)
$ curl -v www.oschina.net
* Rebuilt URL to: www.oschina.net/
* timeout on name lookup is not supported
* Trying 116.211.174.177...% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed0 0 0 0 0 0 0 0 --:--:-- 0:00:14 --:--:-- 0
想看更详细的就使用
curl --trace output.txt www.oschina.net
打开output.txt文件就有相关信息
$ curl.exe 'http://localhost:9200/?pretty'% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed
100 432 100 432 0 0 28800 0 --:--:-- --:--:-- --:--:-- 28800{"name" : "5ZS6Wl8","cluster_name" : "elasticsearch","cluster_uuid" : "gY8furXtSsGJr5Nmlv0oNg","version" : {"number" : "6.1.1","build_hash" : "bd92e7f","build_date" : "2017-12-17T20:23:25.338Z","build_snapshot" : false,"lucene_version" : "7.1.0","minimum_wire_compatibility_version" : "5.6.0","minimum_index_compatibility_version" : "5.0.0"},"tagline" : "You Know, for Search"
}
