linux中curl命令详解

linux中curl命令的使用详情:

1、curl url(获取该网址的文本信息)

curl www.zhujy.com

这就是获取的www.zhujy.com信息

<!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style>     body {         width: 35em;         margin: 0 auto;         font-family: Tahoma, Verdana, Arial, sans-serif;     } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html>

2、curl -i url(获取该网址的文本信息以及协议头部信息)

这就是获取的www.zhujy.com文本信息以及协议头部信息。

HTTP/1.1 200 OK Server: nginx/1.14.0 Date: Mon, 11 Mar 2019 02:06:55 GMT Content-Type: text/html Content-Length: 612 Last-Modified: Mon, 29 Oct 2018 09:52:22 GMT Connection: keep-alive ETag: "5bd6d856-264" Accept-Ranges: bytes <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style>     body {         width: 35em;         margin: 0 auto;         font-family: Tahoma, Verdana, Arial, sans-serif;     } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working.

3、curl -x proxy url(使用代理获取网页文本信息)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">     <head>         <title>Test Page for the Nginx HTTP Server on Fedora</title>         <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />         <style type="text/css">             /*<![CDATA[*/             body {                 background-color: #fff;                 color: #000;                 font-size: 0.9em;                 font-family: sans-serif,helvetica;                 margin: 0;                 padding: 0;             }             :link {                 color: #c00;             }             :visited {                 color: #c00;             }             a:hover {                 color: #f50;             }             h1 {                 text-align: center;                 margin: 0;                 padding: 0.6em 2em 0.4em;                 background-color: #294172;                 color: #fff;                 font-weight: normal;                 font-size: 1.75em;                 border-bottom: 2px solid #000;             }             h1 strong {                 font-weight: bold;                 font-size: 1.5em;             }             h2 {                 text-align: center;                 background-color: #3C6EB4;                 font-size: 1.1em;                 font-weight: bold;                 color: #fff;                 margin: 0;                 padding: 0.5em;                 border-bottom: 2px solid #294172;             }             hr {                 display: none;             }             .content {                 padding: 1em 5em;             }             .alert {                 border: 2px solid #000;             }             img {                 border: 2px solid #fff;                 padding: 2px;                 margin: 2px;             }             a:hover img {                 border: 2px solid #294172;             }             .logos {                 margin: 1em;                 text-align: center;             }             /*]]>*/         </style>     </head>     <body>         <h1>Welcome to <strong>nginx</strong> on Fedora!</h1>         <div>             <p>This page is used to test the proper operation of the             <strong>nginx</strong> HTTP server after it has been             installed. If you can read this page, it means that the             web server installed at this site is working             properly.</p>             <div>                 <h2>Website Administrator</h2>                 <div>                     <p>This is the default <tt>index.html</tt> page that                     is distributed with <strong>nginx</strong> on                     Fedora.  It is located in                     <tt>/usr/share/nginx/html</tt>.</p>                     <p>You should now put your content in a location of                     your choice and edit the <tt>root</tt> configuration                     directive in the <strong>nginx</strong>                     configuration file                     <tt>/etc/nginx/nginx.conf</tt>.</p>                 </div>             </div>             <div>                 <a href="http://nginx.net/"><img                     src="nginx-logo.png"                      alt="[ Powered by nginx ]"                     width="121" height="32" /></a>                 <a href="http://fedoraproject.org/"><img                      src="poweredby.png"                      alt="[ Powered by Fedora ]"                      width="88" height="31" /></a>             </div>         </div>     </body> </html>

4、curl -X POST –header"Content-Type:application/json" –data ‘{}’ url (使用post模拟json格式请求接口)

curl -X POST --header "Content-Type:application/json"  --data '{}'  127.0.0.1:8088/user/getAllUserInfo
{"resultCode":"0","resultMsg":"成功","data":{"userList":[{"id":"a6fc8f27-e598-11e8-ba67-00163e14685b","name":"tom","age":"18","address":"北京1","stage":"NBA"},{"id":"24793d7c-e199-11e8-ba67-00163e14685b","name":"tom","age":"18","address":"北京3","stage":"NBA"},{"id":"247acf89-e599-11e8-ba67-00163e14685b","name":"jerry","age":"18","address":"深圳22","stage":"NBA"},{"id":"247cdafc-e599-11e8-ba67-00163e14685b","name":"james","age":"38","address":"广州d4","stage":"NBA"},{"id":"247ed96c-e599-11e8-ba67-00163e14685b","name":"curry","age":"58","address":"上海fv","stage":"NBA"},{"id":"24805b4e-e599-11e8-ba67-00163e14685b","name":"kaven","age":"78","address":"陇县","stage":"NBA"},{"id":"2481f851-e599-11e8-ba67-00163e14685b","name":"durant","age":"68","address":"富平","stage":"NBA"}]}}

POST 指定请求方式

–header 指定请求头部信息

–data 指定json请求体数据内容

5、curl -I url(仅返回请求头部信息)

curl -I www.zhujy.com.cn
HTTP/1.1 200 OK Server: nginx/1.14.0 Date: Mon, 11 Mar 2019 03:34:29 GMT Content-Type: text/html Content-Length: 612 Last-Modified: Mon, 29 Oct 2018 09:52:22 GMT Connection: keep-alive ETag: "5bd6d856-264" Accept-Ranges: bytes
