Working with messages
|
|
=====================
|
|
|
|
|
|
.. note::
|
|
|
|
These examples assume you have read :ref:`accessing-the-full-api`.
|
|
|
|
|
|
Forwarding messages
|
|
*******************
|
|
|
|
Note that ForwardMessageRequest_ (note it's Message, singular) will *not*
|
|
work if channels are involved. This is because channel (and megagroups) IDs
|
|
are not unique, so you also need to know who the sender is (a parameter this
|
|
request doesn't have).
|
|
|
|
Either way, you are encouraged to use ForwardMessagesRequest_ (note it's
|
|
Message*s*, plural) *always*, since it is more powerful, as follows:
|
|
|
|
.. code-block:: python
|
|
|
|
from telethon.tl.functions.messages import ForwardMessagesRequest
|
|
# note the s ^
|
|
|
|
messages = foo() # retrieve a few messages (or even one, in a list)
|
|
from_entity = bar()
|
|
to_entity = baz()
|
|
|
|
client(ForwardMessagesRequest(
|
|
from_peer=from_entity, # who sent these messages?
|
|
id=[msg.id for msg in messages], # which are the messages?
|
|
to_peer=to_entity # who are we forwarding them to?
|
|
))
|
|
|
|
The named arguments are there for clarity, although they're not needed because
|
|
they appear in order. You can obviously just wrap a single message on the list
|
|
too, if that's all you have.
|
|
|
|
|
|
Searching Messages
|
|
*******************
|
|
|
|
Messages are searched through the obvious SearchRequest_, but you may run
|
|
into issues_. A valid example would be:
|
|
|
|
.. code-block:: python
|
|
|
|
from telethon.tl.functions.messages import SearchRequest
|
|
from telethon.tl.types import InputMessagesFilterEmpty
|
|
|
|
filter = InputMessagesFilterEmpty()
|
|
result = client(SearchRequest(
|
|
peer=peer, # On which chat/conversation
|
|
q='query', # What to search for
|
|
filter=filter, # Filter to use (maybe filter for media)
|
|
min_date=None, # Minimum date
|
|
max_date=None, # Maximum date
|
|
offset_id=0, # ID of the message to use as offset
|
|
add_offset=0, # Additional offset
|
|
limit=10, # How many results
|
|
max_id=0, # Maximum message ID
|
|
min_id=0, # Minimum message ID
|
|
from_id=None # Who must have sent the message (peer)
|
|
))
|
|
|
|
It's important to note that the optional parameter ``from_id`` could have
|
|
been omitted (defaulting to ``None``). Changing it to InputUserEmpty_, as one
|
|
could think to specify "no user", won't work because this parameter is a flag,
|
|
and it being unspecified has a different meaning.
|
|
|
|
If one were to set ``from_id=InputUserEmpty()``, it would filter messages
|
|
from "empty" senders, which would likely match no users.
|
|
|
|
If you get a ``ChatAdminRequiredError`` on a channel, it's probably because
|
|
you tried setting the ``from_id`` filter, and as the error says, you can't
|
|
do that. Leave it set to ``None`` and it should work.
|
|
|
|
As with every method, make sure you use the right ID/hash combination for
|
|
your ``InputUser`` or ``InputChat``, or you'll likely run into errors like
|
|
``UserIdInvalidError``.
|
|
|
|
|
|
Sending stickers
|
|
****************
|
|
|
|
Stickers are nothing else than ``files``, and when you successfully retrieve
|
|
the stickers for a certain sticker set, all you will have are ``handles`` to
|
|
these files. Remember, the files Telegram holds on their servers can be
|
|
referenced through this pair of ID/hash (unique per user), and you need to
|
|
use this handle when sending a "document" message. This working example will
|
|
send yourself the very first sticker you have:
|
|
|
|
.. code-block:: python
|
|
|
|
# Get all the sticker sets this user has
|
|
sticker_sets = client(GetAllStickersRequest(0))
|
|
|
|
# Choose a sticker set
|
|
sticker_set = sticker_sets.sets[0]
|
|
|
|
# Get the stickers for this sticker set
|
|
stickers = client(GetStickerSetRequest(
|
|
stickerset=InputStickerSetID(
|
|
id=sticker_set.id, access_hash=sticker_set.access_hash
|
|
)
|
|
))
|
|
|
|
# Stickers are nothing more than files, so send that
|
|
client(SendMediaRequest(
|
|
peer=client.get_me(),
|
|
media=InputMediaDocument(
|
|
id=InputDocument(
|
|
id=stickers.documents[0].id,
|
|
access_hash=stickers.documents[0].access_hash
|
|
),
|
|
caption=''
|
|
)
|
|
))
