"""Use this method to retrieve a chunk of the history of a chat.
|
|
|
|
You can get up to 100 messages at once.
|
|
For a more convenient way of getting a chat history see :meth:`iter_history`.
|
|
|
|
Args:
|
|
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).
|
|
|
|
limit (``int``, *optional*):
|
|
Limits the number of messages to be retrieved.
|
|
By default, the first 100 messages are returned.
|
|
|
|
offset (``int``, *optional*):
|
|
Sequential number of the first message to be returned. Defaults to 0 (most recent message).
|
|
Negative values are also accepted and become useful in case you set offset_id or offset_date.
|
|
|
|
offset_id (``int``, *optional*):
|
|
Pass a message identifier as offset to retrieve only older messages starting from that message.
|
|
|
|
offset_date (``int``, *optional*):
|
|
Pass a date in Unix time as offset to retrieve only older messages starting from that date.
|
|
|
|
reverse (``bool``, *optional*):
|
|
Pass True to retrieve the messages in reversed order (from older to most recent).
|
|
|
|
Returns:
|
|
On success, a :obj:`Messages <pyrogram.Messages>` object is returned.
|
|
|
|
Raises:
|
|
:class:`Error <pyrogram.Error>` in case of a Telegram RPC error.
