curl方式的下载命令

curl -L "http://download.oracle.com/otn-pub/java/jdk/8u101-b13/jdk-8u101-linux-i586.tar.gz" \
-H "Cookie: oraclelicense=accept-securebackup-cookie"  \
-H "Connection: keep-alive" -O
# curl要通过-O参数才能下载文件，否则只是将内容输出到控制台
# 其中-L参数能够追踪重定向的地址，不加-L只能返回302的结果，cookies中有用的内容是同意协议那一部分
# Connection: keep-alive这句要加上，否则下载速度会变成蜗牛

wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u101-b13/jdk-8u101-linux-i586.tar.gz
# 其中 --no-check-certificate表示不校验SSL证书，因为中间的两个302会访问https，会涉及到证书的问题，不校验能快一点，影响不大，另一个--no-cookies表示不使用cookies,当然首次在header里指定的会带上，后面重定向的就不带了，这个影响也不大，可以不加。
