</body>
</html>

2、curl -i url(获取该网址的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" "">
<html xmlns="" 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: }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 beeninstalled.

</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 '{}'

{"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 .cn

HTTP/1.1 200 OK
Server: nginx/1.14.0

Content-Type: text/html
