连接 aiogram 和 telethon

Question

我正在编写一个电报机器人，需要使用 telethon 客户端发送一些消息，并使用 aiogram 发送一些消息。他犯了一个我不明白的错误

我试过这段代码：

bot = Bot(token=bot_token)
dp = Dispatcher()
client = TelegramClient("session", api_id, api_hash).start(bot_token=bot_token)


@dp.message(CommandStart())
async def start(message: types.Message):
    await message.answer("text aiogram")
    await client_send(message)


async def client_send(message: types.Message):
    async with client:
        await client.send_message(message.chat.id, "text telethon")


async def main():
    await dp.start_polling(bot)

if __name__ == '__main__':
    asyncio.run(main())

当机器人收到消息时，我会得到这么长的回溯：

Cause exception while process update id=xxx by bot id=xxx
RuntimeError: The asyncio event loop must not change after connection (see the FAQ for details)

我如何连接和使用这两个库

Answer 1

asyncio.run

创建一个新的事件循环。建立连接后（使用 Telethon 的

.start()

进行连接），您无法更改循环（

.start()

线使用默认循环，但

asyncio.run

创建一个新循环）。

删除

.start()

。当您使用

async with client

时，也会调用

.start()

，因此第一个是多余的并会导致问题。

另请注意，Telethon 也能够控制机器人帐户。如果您同时需要用户和机器人，使用单个库可能会更简单。
