短信预约 -IT技能 免费直播动态提醒
这篇文章主要介绍了Linux系统中如何使用curl命令，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
curl是一个非常实用的、用来与服务器之间传输数据的工具；支持的协议包括 (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS, TELNET and TFTP)，curl设计为无用户交互下完成工作；
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 : 设置用户代理发送给服务器 -e/--referer : 来源网址 --cacert : 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 : 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 : 将url的header信息存放在指定文件中 --basic: 使用HTTP基本认证 -u/--user : 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 : 将网络文件保存为指定的文件中 --limit-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 : 将url中cookie存放在指定文件中 -x/--proxy : 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 : 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curl命令测试HTTP协议实战案例
