一.curl工具概述
curl是基于URL语法在命令行方式下工作的文件传输工具，它支持FTP，FTPS，HTTP，HTTPS，GOPHER，TELNET，DICT，FILE及LDAP等协议; curl支持HTTPS认证，并且支持HTTP的POST、PUT等方法， FTP上传， kerberos认证，HTTP上传，代理服务器，cookies，用户名/密码认证， 下载文件断点续传，上载文件断点续传, http代理服务器管道（ proxy tunneling）; curl还支持IPv6，socks5代理服务器，通过http代理服务器上传文件到FTP服务器等，功能十分强大。
二.curl工具常用选项高数
语法格式：
curl [options] [URL...] 常用选项如下所示:
-A/--user-agent <string>:
设置用户代理发送给服务器 -e/--referer <URL>:
来源网址 --cacert <file>:
CA证书 (SSL) -k/--insecure:
允许忽略证书进行 SSL 连接 --compressed:
要求返回是压缩的格式 -H/--header <line>:
自定义首部信息传递给服务器 -i:
显示页面内容，包括报文首部信息 -I/--head:
只显示响应报文首部信息 -D/--dump-header <file>:
将url的header信息存放在指定文件中 --basic:
使用HTTP基本认证
-u/--user <user[:password]>:
设置服务器的用户和密码
-L:
如果有3xx响应码，重新发请求到新位置
-O:
使用URL中默认的文件名保存文件到本地
-o <file>:
将网络文件保存为指定的文件中
--limit-rate <rate>:
设置传输速度
-0/--http1.0:
数字0，使用HTTP 1.0
-v/--verbose:
更详细 -C:
选项可对文件使用断点续传功能
-c/--cookie-jar <file name>:
将url中cookie存放在指定文件中
-x/--proxy <proxyhost[:port]>:
指定代理服务器地址
-X/--request <command>:
向服务器发送指定请求方法
-U/--proxy-user <user:password>:
代理服务器用户和密码
-T:
选项可将指定的本地文件上传到FTP服务器上
--data/-d:
方式指定使用POST方式传递数据
-b name=data:
从服务器响应set-cookie得到值，返回给服务器
三.curl命令测试HTTP协议实战案例
1>."-A/--user-agent <string>"案例
[root@node101.yinzhengjie.org.cn ~]# curl -A 'Chrome/78.0.3904.108 Safari/537.36' http://node107.yinzhengjie.org.cn #设置用户代理发送给服务器,其实就是封装了请求报文中的"User-Agent"参数，可以结合"-v"选项查看的更详细。
