Running custom script before handling WebDAV request

Help and Support

What is the problem you are having with rclone?

More of a question than a problem. I'm trying to use rclone as a bootleg short-lived WebDAV server to access Zotero storage from my computer on the Zotero iOS app. The Zotero app incorporates a WebDAV client for achieving this.

It looks like the client actually requests a compressed (.zip) format of the directory which does not exist in the file system. E.g., in the logs you can see it requests 2ZWG8DVK.zip. The directory 2ZWG8DVK exists and actually contains the necessary file.

My question is: is there any sort of pre-request-handle hook that I can plug into rclone to zip the directory right before rclone handles the request? Otherwise I guess I can just .zip everything everytime I run the server.

Run the command 'rclone version' and share the full output of the command.

rclone v1.59.0
- os/version: arch "rolling" (64 bit)
- os/kernel: 5.18.16-arch1-1 (x86_64)
- os/type: linux
- os/arch: amd64
- go/version: go1.18.3
- go/linking: dynamic
- go/tags: none

Which cloud storage system are you using? (eg Google Drive)

None / the file system.

The command you were trying to run

rclone -vv serve webdav --addr 192.168.1.42:8080 --baseurl "/zotero" --user yyy --pass xxx storage/

The rclone config contents with secrets removed.

Empty

There isn't anyway to do that in rclone that I'm aware of.

You'd have to build an action prior to the rclone serve I'd imagine as you suggested.

I see. Thanks for taking the time to answer.

This would need a patch to rclone to implement this I think.

It would be interesting to see what headers the client sends - maybe this is some standardish webdav extension?
