Creating a Client
|
||
|
|
===================
|
||
|
|
|
||
|
|
Before working with Telegram's API, you need to get your own API ID and hash:
|
||
|
|
|
||
|
|
1. Follow `this link <https://my.telegram.org/>`_ and login with your phone number.
|
||
|
|
|
||
|
|
2. Click under API Development tools.
|
||
|
|
|
||
|
|
3. A *Create new application* window will appear. Fill in your application details.
|
||
|
|
There is no need to enter any *URL*, and only the first two fields (*App title* and *Short name*)
|
||
|
|
can be changed later as far as I'm aware.
|
||
|
|
|
||
|
|
4. Click on *Create application* at the end. Remember that your **API hash is secret**
|
||
|
|
and Telegram won't let you revoke it. Don't post it anywhere!
|
||
|
|
|
||
|
|
Once that's ready, the next step is to create a ``TelegramClient``.
|
||
|
|
This class will be your main interface with Telegram's API, and creating one is very simple:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
from telethon import TelegramClient
|
||
|
|
|
||
|
|
# Use your own values here
|
||
|
|
api_id = 12345
|
||
|
|
api_hash = '0123456789abcdef0123456789abcdef'
|
||
|
|
phone_number = '+34600000000'
|
||
|
|
|
||
|
|
client = TelegramClient('some_name', api_id, api_hash)
|
||
|
|
|
||
|
|
Note that ``'some_name'`` will be used to save your session (persistent information such as access key and others)
|
||
|
|
as ``'some_name.session'`` in your disk. This is simply a JSON file which you can (but shouldn't) modify.
|
||
|
|
|
||
|
|
Before using the client, you must be connected to Telegram. Doing so is very easy:
|
||
|
|
|
||
|
|
``client.connect() # Must return True, otherwise, try again``
|
||
|
|
|
||
|
|
You may or may not be authorized yet. You must be authorized before you're able to send any request:
|
||
|
|
|
||
|
|
``client.is_user_authorized() # Returns True if you can send requests``
|
||
|
|
|
||
|
|
If you're not authorized, you need to ``.sign_in()``:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
client.send_code_request(phone_number)
|
||
|
|
myself = client.sign_in(phone_number, input('Enter code: '))
|
||
|
|
# If .sign_in raises PhoneNumberUnoccupiedError, use .sign_up instead
|
||
|
|
# If .sign_in raises SessionPasswordNeeded error, call .sign_in(password=...)
|
||
|
|
# You can import both exceptions from telethon.errors.
|
||
|
|
|
||
|
|
``myself`` is your Telegram user.
|
||
|
|
You can view all the information about yourself by doing ``print(myself.stringify())``.
|
||
|
|
You're now ready to use the client as you wish!
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
If you want to use a **proxy**, you have to `install PySocks`__ (via pip or manual)
|
||
|
|
and then set the appropriated parameters:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
import socks
|
||
|
|
client = TelegramClient('session_id',
|
||
|
|
api_id=12345, api_hash='0123456789abcdef0123456789abcdef',
|
||
|
|
proxy=(socks.SOCKS5, 'localhost', 4444)
|
||
|
|
)
|
||
|
|
|
||
|
|
The ``proxy=`` argument should be a tuple, a list or a dict,
|
||
|
|
consisting of parameters described `here`__.
