« Content-Disposition : filename="filename.ext" » handling

[ejemba]

Given the following

$ bat -download=true http://127.0.0.1:8080/3,0140231f47.jpg
HTTP/1.1 200 OK
Last-Modified : Thu, 29 Oct 2015 13:06:15 GMT

Accept-Ranges : bytes
Content-Disposition : filename="dog-spoon-lobster.jpg"
Content-Length : 70059
Content-Type : image/jpeg
Etag : "d1ca1636"

Downloading to ""dog-spoon-lobster.jpg""
68.42 KB / 68.42 KB 

The file resulting is literaly "dog-spoon-lobster.jpg" it should have been dog-spoon-lobster.jpg

$ ls -l
total 184
-rw-r--r-- 1 me users 70059 29 oct.  14:33 "dog-spoon-lobster.jpg"

It looks like Content-Disposition does not remove double quotes ?

I put together a simple python script to repro this. It's a simple http file server that forces the Content-Disposition header to be included.

# Download script from gist: https://gist.github.com/nicr9/d3d0a96f39c4ac7956dfad74b5b411c6
$ wget -O content_disposition.py https://gist.githubusercontent.com/nicr9/d3d0a96f39c4ac7956dfad74b5b411c6/raw/89eb60f547285fb7993cf61940a29e1d83bddc87/content_disposition.py

# Run file server in cwd
$ python content_disposition.py &

# Download server file
$ bat -download http://localhost:8000/content_disposition.py

# Check that the filename is wrapped in quotes:
$ ls -alF \"*\"
