Wget
301/302 重定向时无法检测文件名。例如,从http://www.mysql.com/downloads/mirror.php?id=408580下载 MySQL 源代码
wget http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/
该文件将另存为index.html
wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz
该文件将另存为mysql-5.5.25a-linux2.6-x86_64.tar.gz
但第一个 url 只是第二个 URL 的重定向,如下所示:
curl -I http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/
HTTP/1.1 302 Found

如何wget
将http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.25a-linux2.6-x86_64.tar.gz/from/http://cdn.mysql.com/保存为“.tar.gz”自动(不使用-O
参数)?
