Getting Started

import qbittorrentapi

# instantiate a Client using the appropriate WebUI configuration
conn_info = dict(
    host="localhost",
    port=8080,
    username="admin",
    password="adminadmin",
)
qbt_client = qbittorrentapi.Client(**conn_info)

# the Client will automatically acquire/maintain a logged-in state
# in line with any request. therefore, this is not strictly necessary;
# however, you may want to test the provided login credentials.
try:
    qbt_client.auth_log_in()
except qbittorrentapi.LoginFailed as e:
    print(e)

# if the Client will not be long-lived or many Clients may be created
# in a relatively short amount of time, be sure to log out:
qbt_client.auth_log_out()

# or use a context manager:
with qbittorrentapi.Client(**conn_info) as qbt_client:
    if qbt_client.torrents_add(urls="...") != "Ok.":
        raise Exception("Failed to add torrent.")

# display qBittorrent info
print(f"qBittorrent: {qbt_client.app.version}")
print(f"qBittorrent Web API: {qbt_client.app.web_api_version}")
for k, v in qbt_client.app.build_info.items():
    print(f"{k}: {v}")

# retrieve and show all torrents
for torrent in qbt_client.torrents_info():
    print(f"{torrent.hash[-6:]}: {torrent.name} ({torrent.state})")

# stop all torrents
qbt_client.torrents.stop.all()
