查看文档，因此您可以了解如何正确设置 get_messages 请求.

Take a look into the documentation, so you can see how to set up correctly the get_messages request.

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())
