"""Get one or more messages from a chat by using message identifiers.
|
|
|
|
You can retrieve up to 200 messages at once.
|
|
|
|
Parameters:
|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
For your personal cloud (Saved Messages) you can simply use "me" or "self".
|
|
For a contact that exists in your Telegram address book you can use his phone number (str).
|
|
|
|
message_ids (``iterable``, *optional*):
|
|
Pass a single message identifier or a list of message ids (as integers) to get the content of the
|
|
message themselves. Iterators and Generators are also accepted.
|
|
|
|
reply_to_message_ids (``iterable``, *optional*):
|
|
Pass a single message identifier or a list of message ids (as integers) to get the content of
|
|
the previous message you replied to using this message. Iterators and Generators are also accepted.
|
|
If *message_ids* is set, this argument will be ignored.
|
|
|
|
replies (``int``, *optional*):
|
|
The number of subsequent replies to get for each message.
|
|
Pass 0 for no reply at all or -1 for unlimited replies.
|
|
Defaults to 1.
|
|
|
|
Returns:
|
|
:obj:`Message` | List of :obj:`Message`: In case *message_ids* was an integer, the single requested message is
|
|
returned, otherwise, in case *message_ids* was an iterable, the returned value will be a list of messages,
|
|
even if such iterable contained just a single element.
|
|
|
|
Example:
|
|
.. code-block:: python
|
|
|
|
# Get one message
|
|
app.get_messages("pyrogramchat", 51110)
|
|
|
|
# Get more than one message (list of messages)
|
|
app.get_messages("pyrogramchat", [44625, 51110])
|
|
|
|
# Get message by ignoring any replied-to message
|
|
app.get_messages(chat_id, message_id, replies=0)
|
|
|
|
# Get message with all chained replied-to messages
|
|
app.get_messages(chat_id, message_id, replies=-1)
|
|
|
|
# Get the replied-to message of a message
|
|
app.get_messages(chat_id, reply_to_message_ids=message_id)
