+ | |||
+ | curl performs SSL certificate verification by default, using a "bundle" | ||
+ | of Certificate Authority (CA) public keys (CA certs). If the default | ||
+ | bundle file isn't adequate, you can specify an alternate file | ||
+ | using the --cacert option. | ||
+ | If this HTTPS server uses a certificate signed by a CA represented in | ||
+ | the bundle, the certificate verification probably failed due to a | ||
+ | problem with the certificate (it might be expired, or the name might | ||
+ | not match the domain name in the URL). | ||
+ | If you'd like to turn off curl's verification of the certificate, use | ||
+ | the -k (or --insecure) option. | ||

常用参数
-o: --output <file> Write to file instead of stdout 内置option:-o(小写)保存网页 将文件保存为命令行中指定的文件名的文件中 借助-o选项,提供名称,下载文件会以该名称保存;如使用-O选项,文件就会以原始名称保存。 -O:使用URL中默认的文件名保存文件到本地 -L, --location Follow redirects 进行强制重定向 --location-trusted Like --location, and send auth to other hosts --login-options <options> Server login options --mail-auth <address> Originator address of the original email --mail-from <address> Mail from this address --mail-rcpt <address> Mail to this address 下载2022 -L, --location Follow redirects 进行强制重定向 -s/--silent 静音模式。不输出任何东西 -O:使用URL中默认的文件名保存文件到本地 curl -L -s -O https://kuboard.cn/statics/learning/job/job-tmpl.yaml 举个栗子 curl -L linux.net/lnmp.sh -o 1.sh 把lnmp.sh 下载回来 并重命令为1.sh 指令:curl 在linux中curl是一个利用URL规则在命令行下工作的文件传输工具,可以说是一款很强大的http命令行工具。它支持文件的上传和下载,是综合传输工具,但按传统,习惯称url为下载工具。 语法:# curl [option] [url] 常见参数: -A/--user-agent <string> 设置用户代理发送给服务器 -b/--cookie <name=string/file> cookie字符串或文件读取位置 -c/--cookie-jar <file> 操作结束后把cookie写入到这个文件中 -C/--continue-at <offset> 断点续转 -D/--dump-header <file> 把header信息写入到该文件中 -e/--referer 来源网址 -f/--fail 连接失败时不显示http错误 -o/--output 把输出写到该文件中 -O/--remote-name 把输出写到该文件中,保留远程文件的文件名 -r/--range <range> 检索来自HTTP/1.1或FTP服务器字节范围 -s/--silent 静音模式。不输出任何东西 -T/--upload-file <file> 上传文件 -u/--user <user[:password]> 设置服务器的用户和密码 -w/--write-out [format] 什么输出完成后 -x/--proxy <host[:port]> 在给定的端口上使用HTTP代理 -#/--progress-bar 用进度条显示当前的传送状态 用curl的内置option就好,存下http的结果,用这个option: -o curl -o page.html http://www.yahoo.com 大写的O,这么用:这样,就可以按照服务器上的文件名,自动存在本地了 curl -O http://cgi2.tky.3web.ne.jp/~zzh/screen1.JPG 访问不到?肯定是你的proxy没有设定了。 使用curl的时候,用这个option可以指定http访问所使用的proxy服务器及其端口: -x curl -x 123.45.67.89:1080 -o page.html http://www.yahoo.com 下载 curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py curl -fsSL -o php.tar.xz https://www.php.net/distributions/php-7.4.22.tar.xz 其它例子本身就是一个sh脚本 哈哈 写得不错 https://test.docker.com/ curl -fsSL https://test.docker.com/ | bash curl -fsSL https://test.com/lnmp.sh | bash -f/--fail 连接失败时不显示http错误 -s/--silent 静音模式。不输出任何东西 -S, --show-error Show error. With -s, make curl show errors when they occur -L, --location Follow redirects (H) or wget http://xxx/xxx.sh -O- | bash
