问题描述
使用 curl 下载文件时，我如何跟踪链接位置并将其用作输出文件名(事先不知道远程文件名)?
When downloading a file using curl, how would I follow a link location and use that for the output filename (without knowing the remote filename in advance)?
例如，如果单击下面的链接，您将下载名为pythoncomplete.vim"的文件.但是使用 curl 的 -O 和 -L 选项，文件名只是原始的远程名称，一个笨拙的download_script.php?src_id=10872."
For example, if one clicks on the link below, you would download a filenamed "pythoncomplete.vim." However using curl's -O and -L options, the filename is simply the original remote-name, a clumsy "download_script.php?src_id=10872."
curl -O -L http://www.vim.org/scripts/download_script.php?src_id=10872
为了下载具有正确文件名的文件，您必须提前知道文件名:
In order to download the file with the correct filename you would have to know the name of the file in advance:
curl -o pythoncomplete.vim -L http://www.vim.org/scripts/download_script.php?src_id=10872
如果您可以在不知道名称的情况下下载文件，那就太好了，如果没有，还有其他方法可以通过命令行快速拉下重定向的文件吗?
It would be excellent if you could download the file without knowing the name in advance, and if not, is there another way to quickly pull down a redirected file via command line?
推荐答案
远程端使用 Content-Disposition 标头发送文件名.
The remote side sends the filename using the Content-Disposition header.
curl 7.21.2 或更新版本会自动执行此操作.
curl 7.21.2 or newer does this automatically if you specify --remote-header-name / -J.
curl -O -J -L $url
