文件已过期？

Answer 1

尝试使用网络浏览器访问https://www.dropbox.com/s/hn28qgjn59nud6h/ceph-all-in-one.box– Dropbox 显示一条消息：

404 我们找不到您要查找的内容。

（虽然显示消息确实需要 javascript...）

通过以下方式请求页面curl：

$ curl -IL 'https://www.dropbox.com/s/hn28qgjn59nud6h/ceph-all-in-one.box'
HTTP/2 301
...
location: /s/raw/hn28qgjn59nud6h/ceph-all-in-one.box
...
HTTP/2 400

使用不同的User-Agent标题：

$ curl -A cruel -IL 'https://www.dropbox.com/s/hn28qgjn59nud6h/ceph-all-in-one.box'
HTTP/2 200
...
$ curl -s -A cruel 'https://www.dropbox.com/s/hn28qgjn59nud6h/ceph-all-in-one.box' |
> grep -om1 '<title>[^<]*'
