Welcome to transmission-rpc’s documentation!¶

transmission-rpc is a python3 library to help your control your transmission daemon remotely.

quick start¶

from transmission_rpc import Client

torrent_url = 'http://releases.ubuntu.com/' + \
              '18.04/ubuntu-18.04.1-desktop-amd64.iso.torrent'
c = Client(host='localhost', port=9091, username='transmission', password='password')
c.add_torrent(torrent_url)

########

from transmission_rpc import Client

c = Client(username='transmission', password='password')

torrent_url = 'magnet:?xt=urn:btih:e84213a794f3ccd890382a54' + \
              'a64ca68b7e925433&dn=ubuntu-18.04.1-desktop-amd64.iso'
c.add_torrent(torrent_url)

########

from transmission_rpc import Client
import requests

torrent_url = 'http://releases.ubuntu.com/' + \
              '18.04/ubuntu-18.04.1-desktop-amd64.iso.torrent'
r = requests.get(torrent_url)
with open('a', 'wb') as f:
    f.write(r.content)
c = Client(username='trim21', password='123456')
with open('a', 'rb') as f:
    c.add_torrent(f)

client.add_torrent support a url string(could start with file:), file-like object(object with read() method) or base64 encoded torrent file content.

if torrent starts with file, transmission-rpc will read it from disk and base64 encode it.

Arguments¶

Each method has it own arguments. You can pass arguments as kwargs when you call methods.

But in python, - can’t be used in a variable name, so you need to replace - with _.

For example, torrent-add method support arguments download-dir, you should call method like this.

from transmission_rpc import Client

Client().add_torrent(torrent_url, download_dir='/path/to/download/dir')

transmission-rpc will put {"download-dir": "/path/to/download/dir"} in arguments.

helper¶

If you want to know what kwargs you can use for a method, you can use transmission_rpc.utils.get_arguments() to get support arguments. For example, transmission 2.94 is rpc version 15, so just call print(get_arguments('torrent-add', 15))

rpc method and class method are not same, but reversed

you can find rpc version by transmission version from transmission wiki

Client¶

Client is the class handling the Transmission JSON-RPC client protocol.

Torrent ids¶

Many functions in Client takes torrent id. You can find torrent-ids spec in official docs

Timeouts¶

Since most methods results in HTTP requests against Transmission, it is possible to provide a argument called timeout. Default timeout is 30 seconds.

class transmission_rpc.client.Client(*, protocol: typing_extensions.Literal[http, https] = 'http', username: str = None, password: str = None, host: str = '127.0.0.1', port: int = 9091, path: str = '/transmission/', timeout: Union[int, float] = 30.0, logger: logging.Logger = <Logger transmission-rpc (ERROR)>)[source]¶

add_torrent(torrent: Union[BinaryIO, str], timeout: Optional[Union[int, float, Tuple[Union[int, float], Union[int, float]]]] = None, **kwargs: Any) → str[source]¶

Add torrent to transfers list. Takes a uri to a torrent or base64 encoded torrent data in torrent. You can find examples in test code tests/test_client.py

Note

url starts with file:// will be load by this package instead of transmission daemon

Torrent¶

class transmission_rpc.torrent.Torrent(client: Client, fields: Dict[str, Any])[source]¶

Torrent is a class holding the data received from Transmission regarding a bittorrent transfer.

All fetched torrent fields are accessible through this class using attributes. This class has a few convenience properties using the torrent data.

property date_active¶: the attribute “activityDate” as datetime.datetime.

property date_added¶: the attribute “addedDate” as datetime.datetime.

property date_done¶: the attribute “doneDate” as datetime.datetime. returns None if “doneDate” is invalid.

property date_started¶: the attribute “startDate” as datetime.datetime.

property download_limit¶

Can be a number or None.

property eta¶: the “eta” as datetime.timedelta.

files() → List[transmission_rpc.lib_types.File][source]¶

Get list of files for this torrent.

This function returns a dictionary with file information for each file. The file information is has following fields:

format_eta() → str[source]¶

Returns the attribute eta formatted as a string.

If eta is -1 the result is ‘not available’
If eta is -2 the result is ‘unknown’
Otherwise eta is formatted as <days> <hours>:<minutes>:<seconds>.

property seed_ratio_mode¶

Seed ratio mode as string. Can be one of ‘global’, ‘single’ or ‘unlimited’.
