如何查看我的所有联系人并向他们发送消息?我使用 Telethon(API 电报 python)。
from telethon.tl.functions.contacts import ResolveUsernameRequest
from telethon.tl.types import InputChannelEmpty
from telethon import TelegramClient
from telethon.tl.types.messages import Messages
from telethon.tl.types.contacts import Contacts
api_id = 1****
api_hash = '5fbd2d************************'
client = TelegramClient('arta0', api_id, api_hash)
client.connect()
