這篇文章主要介紹了Linux系統(tǒng)中如何使用curl命令，具有一定借鑒價(jià)值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。
curl是一個(gè)非常實(shí)用的、用來與服務(wù)器之間傳輸數(shù)據(jù)的工具；支持的協(xié)議包括 (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS, TELNET and TFTP)，curl設(shè)計(jì)為無用戶交互下完成工作；
語法格式： curl [options] [URL...] 常用選項(xiàng)如下所示: -A/--user-agent : 設(shè)置用戶代理發(fā)送給服務(wù)器 -e/--referer : 來源網(wǎng)址 --cacert : CA證書 (SSL) -k/--insecure: 允許忽略證書進(jìn)行 SSL 連接 --compressed: 要求返回是壓縮的格式 -H/--header : 自定義首部信息傳遞給服務(wù)器 -i: 顯示頁面內(nèi)容，包括報(bào)文首部信息 -I/--head: 只顯示響應(yīng)報(bào)文首部信息 -D/--dump-header : 將url的header信息存放在指定文件中 --basic: 使用HTTP基本認(rèn)證 -u/--user : 設(shè)置服務(wù)器的用戶和密碼 -L: 如果有3xx響應(yīng)碼，重新發(fā)請(qǐng)求到新位置 -O: 使用URL中默認(rèn)的文件名保存文件到本地 -o : 將網(wǎng)絡(luò)文件保存為指定的文件中 --limit-rate : 設(shè)置傳輸速度 -0/--http1.0: 數(shù)字0，使用HTTP 1.0 -v/--verbose: 更詳細(xì) -C: 選項(xiàng)可對(duì)文件使用斷點(diǎn)續(xù)傳功能 -c/--cookie-jar : 將url中cookie存放在指定文件中 -x/--proxy : 指定代理服務(wù)器地址 -X/--request command>: 向服務(wù)器發(fā)送指定請(qǐng)求方法 -U/--proxy-user : 代理服務(wù)器用戶和密碼 -T: 選項(xiàng)可將指定的本地文件上傳到FTP服務(wù)器上 --data/-d: 方式指定使用POST方式傳遞數(shù)據(jù) -b name=data: 從服務(wù)器響應(yīng)set-cookie得到值，返回給服務(wù)器
