Python实现Telegram多Chat ID消息发送报错求助

原本可正常向单个Chat ID发送消息的Telethon代码如下：

import telebot
from telethon.sync import TelegramClient
from telethon.tl.types import InputPeerUser, InputPeerChannel
from telethon import TelegramClient, sync, events

api_id = 00000000
api_hash = 'xxxxxxxxxxxxxxx'
token = 'xxxxxxxxxxxxxxxxxxxxxxx'
my_channel_id = -100000000000 #destination

message = "TEST LTDSH 0-0 Alerts\n\n" + match + "\n" + flagscode + " " + tournamentsts + "\n\U0001F55B Elapsed Time: " + resultlive3 + "\n\u26bd Score: " + resultlive1

phone = '+000000000'

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

client.connect()

if not client.is_user_authorized():
    client.send_code_request(phone)
    client.sign_in(phone, input('Enter the code: '))

try:
    client.send_message(my_channel_id, message, parse_mode='html')
except Exception as e:
    print(e);

client.disconnect()

尝试将目标Chat ID改为列表形式：

my_channel_id = [-100000000, -10000001] #destination

运行时触发错误：Cannot cast list to any kind of Peer.，需解决该问题。

client.send_message()方法仅接受单个Peer对象或单个Chat ID作为目标参数，不支持直接传入列表。要实现批量发送，需遍历列表中的每个Chat ID，逐个调用发送方法：

修改核心逻辑 #

将原有的单个ID发送逻辑替换为遍历列表的循环：

# 定义目标Chat ID列表
my_channel_ids = [-100000000, -10000001]

try:
    # 遍历每个ID发送消息
    for chat_id in my_channel_ids:
        client.send_message(chat_id, message, parse_mode='html')
except Exception as e:
    print(e)

完整修改后的代码 #

import telebot
from telethon.sync import TelegramClient
from telethon.tl.types import InputPeerUser, InputPeerChannel
from telethon import TelegramClient, sync, events

api_id = 00000000
api_hash = 'xxxxxxxxxxxxxxx'
token = 'xxxxxxxxxxxxxxxxxxxxxxx'
# 改用列表存储多个目标Chat ID
my_channel_ids = [-100000000, -10000001] #destination

message = "TEST LTDSH 0-0 Alerts\n\n" + match + "\n" + flagscode + " " + tournamentsts + "\n\U0001F55B Elapsed Time: " + resultlive3 + "\n\u26bd Score: " + resultlive1

phone = '+000000000'

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

client.connect()

if not client.is_user_authorized():
    client.send_code_request(phone)
    client.sign_in(phone, input('Enter the code: '))

try:
    # 遍历列表逐个发送消息
    for chat_id in my_channel_ids:
        client.send_message(chat_id, message, parse_mode='html')
except Exception as e:
    print(e)

client.disconnect()
