其中的AuthParam是一个通用的参数，即使换了服务器也是可以使用的。

在Linux等支持wget的主机上执行

[root@localhost ~]# wget http://download.oracle.com/otn-pub/java/jdk/7u71-b14/jdk-7u71-linux-x64.tar.gz?AuthParam=1413522987_9116ee17c1ff3f10d61497a90fdcfd49[/code] 
就可以下载成功了！

[root@localhost ~]# wget http://download.oracle.com/otn-pub/java/jdk/7u71-b14/jdk-7u71-linux-x64.tar.gz?AuthParam=1413522987_9116ee17c1ff3f10d61497a90fdcfd49 --2014-10-17 05:14:51--  http://download.oracle.com/otn-pub/java/jdk/7u71-b14/jdk-7u71-linux-x64.tar.gz?AuthParam=1413522987_9116ee17c1ff3f10d61497a90fdcfd49 Resolving download.oracle.com... 23.32.241.33, 23.32.241.26

这个AuthParam是有时间限制的，超过时间限制就不能再下载啦，需要重新获取AuthParam：

[root@vultr ~]# wget http://download.oracle.com/otn-pub/java/jdk/7u71-b14/jdk-7u71-linux-x64.tar.gz?AuthParam=1413522987_9116ee17c1ff3f10d61497a90fdcfd49 --2014-10-17 05:20:32--  http://download.oracle.com/otn-pub/java/jdk/7u71-b14/jdk-7u71-linux-x64.tar.gz?AuthParam=1413522987_9116ee17c1ff3f10d61497a90fdcfd49 Resolving download.oracle.com... 184.29.106.105, 184.29.106.106
