Examples with the Client
|
||||
========================
|
||||
|
||||
This section explores the methods defined in the :ref:`telegram-client`
|
||||
with some practical examples. The section assumes that you have imported
|
||||
the ``telethon.sync`` package and that you have a client ready to use.
|
||||
|
||||
.. contents::
|
||||
|
||||
Authorization
|
||||
*************
|
||||
|
||||
Starting the client is as easy as calling `client.start()
|
||||
<telethon.client.auth.AuthMethods.start>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.start()
|
||||
... # code using the client
|
||||
client.disconnect()
|
||||
|
||||
And you can even use a ``with`` block:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
with client:
|
||||
... # code using the client
|
||||
|
||||
|
||||
Group Chats
|
||||
***********
|
||||
|
||||
You can easily iterate over all the :tl:`User` in a chat and
|
||||
do anything you want with them by using `client.iter_participants
|
||||
<telethon.client.chats.ChatMethods.iter_participants>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
for user in client.iter_participants(chat):
|
||||
... # do something with the user
|
||||
|
||||
You can also search by their name:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
for user in client.iter_participants(chat, search='name'):
|
||||
...
|
||||
|
||||
Or by their type (e.g. if they are admin) with :tl:`ChannelParticipantsFilter`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from telethon.tl.types import ChannelParticipantsAdmins
|
||||
|
||||
for user in client.iter_participants(chat, filter=ChannelParticipantsAdmins):
|
||||
...
|
||||
|
||||
|
||||
Open Conversations and Joined Channels
|
||||
**************************************
|
||||
|
||||
The conversations you have open and the channels you have joined
|
||||
are in your "dialogs", so to get them you need to `client.get_dialogs
|
||||
<telethon.client.dialogs.DialogMethods.get_dialogs>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
dialogs = client.get_dialogs()
|
||||
first = dialogs[0]
|
||||
print(first.title)
|
||||
|
||||
You can then use the dialog as if it were a peer:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_message(first, 'hi')
|
||||
|
||||
|
||||
You can access `dialog.draft <telethon.tl.custom.draft.Draft>` or you can
|
||||
get them all at once without getting the dialogs:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
drafts = client.get_drafts()
|
||||
|
||||
|
||||
Downloading Media
|
||||
*****************
|
||||
|
||||
It's easy to `download_profile_photo
|
||||
<telethon.client.downloads.DownloadMethods.download_profile_photo>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.download_profile_method(user)
|
||||
|
||||
Or `download_media <telethon.client.downloads.DownloadMethods.download_media>`
|
||||
from a message:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.download_media(message)
|
||||
client.download_media(message, filename)
|
||||
# or
|
||||
message.download_media()
|
||||
message.download_media(filename)
|
||||
|
||||
Remember that these methods return the final filename where the
|
||||
media was downloaded (e.g. it may add the extension automatically).
|
||||
|
||||
Getting Messages
|
||||
****************
|
||||
|
||||
You can easily iterate over all the `messages
|
||||
<telethon.tl.custom.message.Message>` of a chat with `iter_messages
|
||||
<telethon.client.messages.MessageMethods.iter_messages>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
for message in client.iter_messages(chat):
|
||||
... # do something with the message from recent to older
|
||||
|
||||
for message in client.iter_messages(chat, reverse=True):
|
||||
... # going from the oldest to the most recent
|
||||
|
||||
You can also use it to search for messages from a specific person:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
for message in client.iter_messages(chat, from_user='me'):
|
||||
...
|
||||
|
||||
Or you can search by text:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
for message in client.iter_messages(chat, search='hello'):
|
||||
...
|
||||
|
||||
Or you can search by media with a :tl:`MessagesFilter`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from telethon.tl.types import InputMessagesFilterPhotos
|
||||
|
||||
for message in client.iter_messages(chat, filter=InputMessagesFilterPhotos):
|
||||
...
|
||||
|
||||
If you want a list instead, use the get variant. The second
|
||||
argument is the limit, and ``None`` means "get them all":
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
|
||||
from telethon.tl.types import InputMessagesFilterPhotos
|
||||
|
||||
# Get 0 photos and print the total
|
||||
photos = client.get_messages(chat, 0, filter=InputMessagesFilterPhotos)
|
||||
print(photos.total)
|
||||
|
||||
# Get all the photos
|
||||
photos = client.get_messages(chat, None, filter=InputMessagesFilterPhotos)
|
||||
|
||||
Or just some IDs:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
message_1337 = client.get_messages(chats, ids=1337)
|
||||
|
||||
|
||||
Sending Messages
|
||||
****************
|
||||
|
||||
Just use `send_message <telethon.client.messages.MessageMethods.send_message>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_message('lonami', 'Thanks for the Telethon library!')
|
||||
|
||||
The function returns the `custom.Message <telethon.tl.custom.message.Message>`
|
||||
that was sent so you can do more things with it if you want.
|
||||
|
||||
You can also `reply <telethon.tl.custom.message.Message.reply>` or
|
||||
`respond <telethon.tl.custom.message.Message.respond>` to messages:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
message.reply('Hello')
|
||||
message.respond('World')
|
||||
|
||||
|
||||
Sending Messages with Media
|
||||
***************************
|
||||
|
||||
Sending media can be done with `send_file
|
||||
<telethon.client.uploads.UploadMethods.send_file>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_file(chat, '/my/photos/me.jpg', caption="It's me!")
|
||||
# or
|
||||
client.send_message(chat, "It's me!", file='/my/photos/me.jpg')
|
||||
|
||||
You can send voice notes or round videos by setting the right arguments:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_file(chat, '/my/songs/song.mp3', voice_note=True)
|
||||
client.send_file(chat, '/my/videos/video.mp3', video_note=True)
|
||||
|
||||
You can set a JPG thumbnail for any document:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_file(chat, '/my/documents/doc.txt', thumb='photo.jpg')
|
||||
|
||||
You can force sending images as documents:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_file(chat, '/my/photos/photo.png', force_document=True)
|
||||
|
||||
You can send albums if you pass more than one file:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_file(chat, [
|
||||
'/my/photos/holiday1.jpg',
|
||||
'/my/photos/holiday2.jpg',
|
||||
'/my/drawings/portrait.png'
|
||||
])
|
||||
|
||||
The caption can also be a list to match the different photos.
|
||||
|
||||
Sending Messages with Buttons
|
||||
*****************************
|
||||
|
||||
You must sign in as a bot in order to add inline buttons (or normal
|
||||
keyboards) to your messages. Once you have signed in as a bot specify
|
||||
the `Button <telethon.tl.custom.button.Button>` or buttons to use:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from telethon.tl.custom import Button
|
||||
|
||||
async def callback(event):
|
||||
await event.edit('Thank you!')
|
||||
|
||||
client.send_message(chat, 'Hello!',
|
||||
buttons=Button.inline('Click me', callback))
|
||||
|
||||
|
||||
You can also add the event handler yourself, or change the data payload:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from telethon import events
|
||||
|
||||
@client.on(events.CallbackQuery)
|
||||
async def handler(event):
|
||||
await event.answer('You clicked {}!'.format(event.data))
|
||||
|
||||
client.send_message(chat, 'Pick one', buttons=[
|
||||
[Button.inline('Left'), Button.inline('Right')],
|
||||
[Button.url('Check my site!', 'https://lonamiwebs.github.io')]
|
||||
])
|
||||
|
||||
You can also use normal buttons (not inline) to request the user's
|
||||
location, phone number, or simply for them to easily send a message:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_message(chat, 'Welcome', buttons=[
|
||||
Button.text('Thanks!'),
|
||||
Button.request_phone('Send phone'),
|
||||
Button.request_location('Send location')
|
||||
])
|
||||
|
||||
Forcing a reply or removing the keyboard can also be done:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_message(chat, 'Reply to me', buttons=Button.force_reply())
|
||||
client.send_message(chat, 'Bye Keyboard!', buttons=Button.clear())
|
||||
|
||||
Remember to check `Button <telethon.tl.custom.button.Button>` for more.
|
||||
|
||||
Forwarding Messages
|
||||
*******************
|
||||
|
||||
You can forward up to 100 messages with `forward_messages
|
||||
<telethon.client.messages.MessageMethods.forward_messages>`,
|
||||
or a single one if you have the message with `forward_to
|
||||
<telethon.tl.custom.message.Message.forward_to>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# a single one
|
||||
client.forward_messages(chat, message)
|
||||
# or
|
||||
client.forward_messages(chat, message_id, from_chat)
|
||||
# or
|
||||
message.forward_to(chat)
|
||||
|
||||
# multiple
|
||||
client.forward_messages(chat, messages)
|
||||
# or
|
||||
client.forward_messages(chat, message_ids, from_chat)
|
||||
|
||||
You can also "forward" messages without showing "Forwarded from" by
|
||||
re-sending the message:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_message(chat, message)
|
||||
|
||||
|
||||
Editing Messages
|
||||
****************
|
||||
|
||||
With `edit_message <telethon.client.messages.MessageMethods.edit_message>`
|
||||
or `message.edit <telethon.tl.custom.message.Message.edit>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.edit_message(message, 'New text')
|
||||
# or
|
||||
message.edit('New text')
|
||||
# or
|
||||
client.edit_message(chat, message_id, 'New text')
|
||||
|
||||
Deleting Messages
|
||||
*****************
|
||||
|
||||
With `delete_messages <telethon.client.messages.MessageMethods.delete_messages>`
|
||||
or `message.delete <telethon.tl.custom.message.Message.delete>`. Note that the
|
||||
first one supports deleting entire chats at once!:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.delete_messages(chat, messages)
|
||||
# or
|
||||
message.delete()
|
||||
|
||||
|
||||
Marking Messages as Read
|
||||
************************
|
||||
|
||||
Marking messages up to a certain point as read with `send_read_acknowledge
|
||||
<telethon.client.messages.MessageMethods.send_read_acknowledge>`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
client.send_read_acknowledge(last_message)
|
||||
# or
|
||||
client.send_read_acknowledge(last_message_id)
|
||||
# or
|
||||
client.send_read_acknowledge(messages)
|
||||
|
||||
|
||||
Getting Entities
|
||||
****************
|
||||
|
||||
Entities are users, chats, or channels. You can get them by their ID if
|
||||
you have seen them before (e.g. you probably need to get all dialogs or
|
||||
all the members from a chat first):
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from telethon import utils
|
||||
|
||||
me = client.get_entity('me')
|
||||
print(utils.get_display_name(me))
|
||||
|
||||
chat = client.get_input_entity('username')
|
||||
for message in client.iter_messages(chat):
|
||||
...
|
||||
|
||||
# Note that you could have used the username directly, but it's
|
||||
# good to use get_input_entity if you will reuse it a lot.
|
||||
for message in client.iter_messages('username'):
|
||||
...
|
||||
|
||||
some_id = client.get_peer_id('+34123456789')
|
||||
|
||||
The documentation for shown methods are `get_entity
|
||||
<telethon.client.users.UserMethods.get_entity>`, `get_input_entity
|
||||
<telethon.client.users.UserMethods.get_input_entity>` and `get_peer_id
|
||||
<telethon.client.users.UserMethods.get_peer_id>`.
|
||||
|
||||
Note that the utils package also has a `get_peer_id
|
||||
<telethon.utils.get_peer_id>` but it won't work with things
|
||||
that need access to the network such as usernames or phones,
|
||||
which need to be in your contact list.
