The -J / --remote-header-name logic now records the file name part used in the redirects so that it can use the last one as a name if no Content-Disposition header arrives. Add tests to verify: 1641: -J with a redirect and extract the CD contents in the second response 1642: -J with a redirect but no Content-Disposition, use the name from the Location: header 1643: -J with two redirects, using the last file name and also use queries and fragments to verify them stripped off Closes #20430

# `--remote-header-name`
|
|
|
|
Tell the --remote-name option to use the server-specified Content-Disposition
|
|
filename instead of extracting a filename from the URL. If the server-provided
|
|
filename contains a path, that is stripped off before the filename is used.
|
|
|
|
The file is saved in the current directory, or in the directory specified with
|
|
--output-dir.
|
|
|
|
If the server specifies a filename and a file with that name already exists in
|
|
the destination directory, it is not overwritten and an error occurs - unless
|
|
you allow it by using the --clobber option. If the server does not specify a
|
|
filename then this option has no effect.
|
|
|
|
There is no attempt to decode %-sequences (yet) in the provided filename, so
|
|
this option may provide you with rather unexpected filenames.
|
|
|
|
This feature uses the name from the `filename` field, it does not yet support
|
|
the `filename*` field (filenames with explicit character sets).
|
|
|
|
Starting in 8.19.0, curl falls back and uses the filename extracted from the
|
|
last redirect header if no `Content-Disposition:` header provides a filename.
|
|
|
|
**WARNING**: Exercise judicious use of this option, especially on Windows. A
|
|
rogue server could send you the name of a DLL or other file that could be
|
|
loaded automatically by Windows or some third party software.
