使用wget命令：
wget --no-cookies --no-check-certificate --header "Cookie:gpw_e24=http%3a%2f%2fwww.oracle.com%2ftechnetwork%2fjava%2fjavase%2fdownloads%2fjdk8-downloads-2133151.html;oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u11-b12/jdk-8u11-linux-x64.rpm
代碼運行如下：
[root@localhost local]# wget --no-cookies --no-check-certificate --header "Cookie:gpw_e24=http%3a%2f%2fwww.oracle.com%2ftechnetwork%2fjava%2fjavase%2fdownloads%2fjdk8-downloads-2133151.html;oraclelicense=accept-securebackup-cookie"
