upload and extract zip file with curl

[Kate Alpert]

Hi folks,

I was wondering how to upload and extract a zip file using curl.  With XnatDataClient, I use -l for the local file, but I can't figure out the proper flag with curl.  I've tried -d @filename.zip and -T filename.zip, but no luck.  Anyone know offhand?

Thanks,

Kate

There a dozen ways to do it with cURL.  The -d should work, but I prefer using cURL like I'm filling out a form for easy reading, i.e. -F. 

You can add more parameters if you need to specify subject, experiment labels, etc..  I found it easiest to have this built into the zip folder structure. 

Here is how I've done it using v1.6.3 of XNAT

curl.exe -F "dest=/prearchive/projects/T01" -F "FILE=@C:\yourfilepath.zip" -u USERNAME:PASSWORD http://yourxnaturl

The -F didn't work for me, however, I've made some progress.  The following command uploads the zip file, however, it doesn't extract the contents (instead, I get a file called "upload.unsupported", which is the zip file):

curl -u $uname:$pass -X PUT "$host/data/experiments/$id/assessors/FS_v5-3-0_$id/out/resources/DATA/files?extract=true&overwrite=true&inbody=true" -T test.zip

Any idea how I can achieve the extraction?

Thanks,
Kate

Try removing the “/out"

Removing the "/out" didn't make a difference.

Try adding a file name to the url with a .zip extension.  I’m not sure what the http message curl builds there looks like.  But upload.unsupported tends to show up when XNAT can’t figure out the name of a file.  So, just give it one.  It will be ignored after the file is extracted.

 

curl -u $uname:$pass -X PUT "$host/data/experiments/$id/assessors/FS_v5-3-0_$id/out/resources/DATA/files/test.zip?extract=true&overwrite=true&inbody=true" -T test.zip
