|

class TelegramBareClient:
|
||||
"""Bare Telegram Client with just the minimum -
|
||||
"""
|
||||
A bare Telegram client that somewhat eases the usage of the
|
||||
``MTProtoSender``.
|
||||
|
||||
The reason to distinguish between a MtProtoSender and a
|
||||
TelegramClient itself is because the sender is just that,
|
||||
a sender, which should know nothing about Telegram but
|
||||
rather how to handle this specific connection.
|
||||
Args:
|
||||
session (`str` | `telethon.sessions.abstract.Session`, `None`):
|
||||
The file name of the session file to be used if a string is
|
||||
given (it may be a full path), or the Session instance to be
|
||||
used otherwise. If it's ``None``, the session will not be saved,
|
||||
and you should call :meth:`.log_out()` when you're done.
|
||||
|
||||
The TelegramClient itself should know how to initialize
|
||||
a proper connection to the servers, as well as other basic
|
||||
methods such as disconnection and reconnection.
|
||||
Note that if you pass a string it will be a file in the current
|
||||
working directory, although you can also pass absolute paths.
|
||||
|
||||
This distinction between a bare client and a full client
|
||||
makes it possible to create clones of the bare version
|
||||
(by using the same session, IP address and port) to be
|
||||
able to execute queries on either, without the additional
|
||||
cost that would involve having the methods for signing in,
|
||||
logging out, and such.
|
||||
The session file contains enough information for you to login
|
||||
without re-sending the code, so if you have to enter the code
|
||||
more than once, maybe you're changing the working directory,
|
||||
renaming or removing the file, or using random names.
|
||||
|
||||
api_id (`int` | `str`):
|
||||
The API ID you obtained from https://my.telegram.org.
|
||||
|
||||
api_hash (`str`):
|
||||
The API ID you obtained from https://my.telegram.org.
|
||||
|
||||
connection (`telethon.network.connection.common.Connection`, optional):
|
||||
The connection instance to be used when creating a new connection
|
||||
to the servers. If it's a type, the `proxy` argument will be used.
|
||||
|
||||
Defaults to `telethon.network.connection.tcpfull.ConnectionTcpFull`.
|
||||
|
||||
use_ipv6 (`bool`, optional):
|
||||
Whether to connect to the servers through IPv6 or not.
|
||||
By default this is ``False`` as IPv6 support is not
|
||||
too widespread yet.
|
||||
|
||||
proxy (`tuple` | `dict`, optional):
|
||||
A tuple consisting of ``(socks.SOCKS5, 'host', port)``.
|
||||
See https://github.com/Anorov/PySocks#usage-1 for more.
|
||||
|
||||
update_workers (`int`, optional):
|
||||
If specified, represents how many extra threads should
|
||||
be spawned to handle incoming updates, and updates will
|
||||
be kept in memory until they are processed. Note that
|
||||
you must set this to at least ``0`` if you want to be
|
||||
able to process updates through :meth:`updates.poll()`.
|
||||
|
||||
timeout (`int` | `float` | `timedelta`, optional):
|
||||
The timeout to be used when receiving responses from
|
||||
the network. Defaults to 5 seconds.
|
||||
|
||||
spawn_read_thread (`bool`, optional):
|
||||
Whether to use an extra background thread or not. Defaults
|
||||
to ``True`` so receiving items from the network happens
|
||||
instantly, as soon as they arrive. Can still be disabled
|
||||
if you want to run the library without any additional thread.
|
||||
|
||||
report_errors (`bool`, optional):
|
||||
Whether to report RPC errors or not. Defaults to ``True``,
|
||||
see :ref:`api-status` for more information.
|
||||
|
||||
device_model (`str`, optional):
|
||||
"Device model" to be sent when creating the initial connection.
|
||||
Defaults to ``platform.node()``.
|
||||
|
||||
system_version (`str`, optional):
|
||||
"System version" to be sent when creating the initial connection.
|
||||
Defaults to ``platform.system()``.
|
||||
|
||||
app_version (`str`, optional):
|
||||
"App version" to be sent when creating the initial connection.
|
||||
Defaults to `telethon.version.__version__`.
|
||||
|
||||
lang_code (`str`, optional):
|
||||
"Language code" to be sent when creating the initial connection.
|
||||
Defaults to ``'en'``.
|
||||
|
||||
system_lang_code (`str`, optional):
|
||||
"System lang code" to be sent when creating the initial connection.
|
||||
Defaults to `lang_code`.
