想要从 Telegram 上的 groups/channels 中提取固定消息，我正在使用 Telethon

Question

我正在使用 Telethon API 想要提取我是会员的所有频道的固定消息。请指导我的程序。

谢谢。

Answer 1

use 可以使用 GetFullChannelRequest 和 GetHistoryRequest 方法从一个频道中提取固定消息

from telethon import TelegramClient
from telethon.tl.functions.channels import GetFullChannelRequest
from telethon.tl.functions.messages import GetHistoryRequest
from telethon.tl.types import PeerChannel

api_id = XXXXX
api_hash = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
phone_number = '+98XXXXXXXX'
################################################

client = TelegramClient('session_name',
                    api_id,
                    api_hash
                    )

assert client.connect()
if not client.is_user_authorized():
    client.send_code_request(phone_number)
    me = client.sign_in(phone_number, input('Enter code: '))

channel_entity = client.get_entity(PeerChannel(channel_id))

channel_info = client(GetFullChannelRequest(channel_entity))

pinned_msg_id = channel_info.full_chat.pinned_msg_id

if pinned_msg_id is not None:
    posts = client(GetHistoryRequest(
        channel_entity,
        limit=1,
        offset_date=None,
        offset_id=pinned_msg_id + 1,
        max_id=0,
        min_id=0,
        add_offset=0,
        hash=0
    ))
    print(posts.messages[0].to_dict())

我用的是Telethon V0.19，但是之前的版本都差不多

Answer 2

从 Telethon 1.2 开始，代码简单多了：

from telethon import TelegramClient, types, sync
with TelegramClient('name', api_id, api_hash) as client:
    message = client.get_messages('TelethonChat', ids=types.InputMessagePinned())

但是，这不适用于私人聊天（例如，获取与自己固定的消息）。为此，正如当前接受的答案提示，我们必须获取 Full 对象。对于私聊，这是UserFull by using GetFullUserRequest:

chat = 'me'
full = client(functions.users.GetFullUserRequest(chat))
message = client.get_messages(chat, ids=full.pinned_msg_id)
