简介
curl是一个使用URL语法传输数据的命令行工具，支持DICT、FILE、FTP、FTPS、GOPHER、HTTP、HTTPS、IMAP、IMAPS、LDAP、LDAPS、POP3、POP3S、RTMP、RTSP、SCP、SFTP、SMTP、SMTPS、TELNET和TFTP。
curl支持SSL证书、HTTP POST、HTTP PUT、FTP上传、基于HTTP表单的上传、代理、cookie、用户+密码身份验证（Basic、Digest、NTLM、Negotiate、kerberos…）、文件传输恢复、代理隧道和其他有用技巧。
简而言之就是一个可以在命令行发送请求且接受响应的工具。Windows和Linux都有，且一般都自带这款工具，具体看系统版本。
