curl www.zhujy.com

这就是获取的www.zhujy.com信息

<!DOCTYPE html>

<style>
    body {
        width: 35em;
        margin: 0 auto;

</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。

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 {

                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
