如何从 Telegram 获取公共频道的消息

Question

我需要在电报应用程序中读取一些公共频道的消息，我想将电报频道文本存储在一个文本文件中。我想使用python。我尝试使用 Telethon，但它太复杂了。我的代码有一些错误：

from telethon.tl.functions.messages import (GetHistoryRequest)
from telethon.tl.types import (
PeerChannel
)
client = TelegramClient(username, api_id, api_hash)
client.start()

offset_id = 0
limit = 100
all_messages = []
total_messages = 0
total_count_limit = 0

while True:
    print("Current Offset ID is:", offset_id, "; Total Messages:", total_messages)
    history = client(GetHistoryRequest(
        peer="https://t.me/futballbadnews",
        offset_id=offset_id,
        offset_date=None,
        add_offset=0,
        limit=limit,
        max_id=0,
        min_id=0,
        hash=0
    ))
    if not history.messages:
        break
    messages = history.messages
    for message in messages:
        all_messages.append(message.to_dict())
    offset_id = messages[len(messages) - 1].id
    total_messages = len(all_messages)
    if total_count_limit != 0 and total_messages >= total_count_limit:
        break   

错误：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

---> 24     if not history.messages:

AttributeError: 'coroutine' object has no attribute 'messages'

如何使用 Telethon 从 Telegram 上的公共频道获取消息？

查看文档，了解如何正确设置get_messages请求。

import asyncio
from telethon import TelegramClient
from telethon.tl import functions, types

client = TelegramClient('YOUR_SESSION_NAME', 'YOUR_API_ID', 'YOUR_API_HASH')
client.start()

async def main():
    channel = await client.get_entity('CHANNEL USERNAME')
    messages = await client.get_messages(channel, limit= None) #pass your own args

    #then if you want to get all the messages text
    for x in messages:
        print(x.text) #return message.text


loop = asyncio.get_event_loop()
loop.run_until_complete(main())
