Incorrect URL created when qBittorrent is behind a reverse proxy causing 404 error

[zachoooo]

I have my qBittorrent instance on a docker network along with a reverse proxy and the Web UI is available at http://[HOST]/qBittorrent/. The API is available and works correctly, when using curl or my browser. qbittorrent-api seems to ignore the base url and so I've been getting 404s when trying to use the API. Here is the example code:

qbt_client = qbittorrentapi.Client(host='http://[HOST]/qBittorrent/', username='[USERNAME]', password='[PASSWORD]')

can you please provide one of the working curl statements?

it looks like you're prefixing the Web API paths with qBittorrent....presumably the reverse proxy is then trimming the prefix to the qBittorrent instance. if that's the case, then yes...that is not supported....right now anyway. only the "host" portion (and a port) of the string provided for host is actually used. the absolute paths for the API are hardcoded.

Yes my reverse proxy is trimming the prefixes. qBittorrent currently doesn't support base urls, so I have to trim it to make it available through the reverse proxy. There is an issue open for it on qBittorrent: qbittorrent/qBittorrent#5693

It has been open for quite some time though, so I don't know when that feature will be added. It's possible that this could be considered an upstream issue. Anyways here is the command:

curl http://192.168.1.69/qBittorrent/api/v2/app/version --cookie "[BROWSER COOKIE]"

I copied the cookie from my browser after logging in through the Web UI. I didn't want to include it in case it contained any sensitive information, but the output does work.

hmm....even if they supported a base url, i still think this client would be broken....since it'll always send the default paths....unless qbittorrent just accepted either i guess.

in theory, it wouldn't be too hard to prefix the API path with any user provided base path. just a little concerned that could be a breaking change to some users if they are randomly including a path in their instantiations right now....seems pretty unlikely though.

i can at least mock something up in the next few days. thanks for letting me know.

I guess this is probably better addressed upstream by qBittorrent devs. I can always just use Docker DNS to connect to the API endpoints directly instead of using a reverse proxy. Thanks for looking at it so quickly though!

@zachoooo, I released v2020.12.14. It should now support your instantiation below and make calls using /qBittorrent at the base of the path. Please let me know if you run in to any problems. Thanks.

qbt_client = qbittorrentapi.Client(host='http://[HOST]/qBittorrent/', username='[USERNAME]', password='[PASSWORD]')
