目前我正试图让我的脚本从网站下载一个mysql文件，但它似乎转到302重定向链接。当我在常规（Windows）浏览器中使用完全相同的链接时，它会下载文件。
这里是wget的输出：

正如您可以看到http://6pp.kvdb.net/exports/mysql_sql.txt.gz此网址下载文件（在Windows浏览器中）。
答案 0 :(得分：1)
看起来6pp.kvdb.net重定向到www.d-centralize.nl，而www.d-centralize.nl同时具有IPv4和IPv6地址：
$ host www.d-centralize.nl
www.d-centralize.nl is an alias for ghs.google.com.
ghs.google.com is an alias for ghs.l.google.com.
ghs.l.google.com has address 173.194.69.121
ghs.l.google.com has IPv6 address 2a00:1450:4008:c01::79
他们的网络服务器似乎配置错误。它正在侦听两个地址，但仅在IPv4地址上提供文件。由于您的盒子启用了IPv6，它将更喜欢IPv6地址，这是一个破碎的地址。
尝试wget -4 ...强制服务器的IPv4地址。
