python - 如何更正 "'协程'对象没有属性 'data'“使用Telethon for Telegram时出错？

Question

我正在尝试用 Python 编写一个简单的代码，以自动从 Telegram 上的 channel 下载一些媒体。我正在为此使用 Telethon。

我不断收到无法解决的错误，并且我不明白其原因。

“‘协程’对象没有属性‘数据’”

我也尝试过使用asyncio，但没有成功。 下面是我的最新代码

# In[1]:

import asyncio
loop = asyncio.get_event_loop()
import telethon.sync
from telethon import TelegramClient
from telethon.sync import TelegramClient

loop = asyncio.get_event_loop()


# In[2]: 

api_id = #MyAPIID
api_hash = 'TheHash'
phone_number = '+34xxxxx'
channel_username = 'meanwhileinromania'


# In[3]: 

client = TelegramClient('session1', api_id, api_hash)

client.start()




# In[4]:DOWNLOAD


msgs = client.get_messages(channel_username, limit=100)
for msg in msgs.data:
    if msg.media is not None:
        client.download_media(message=msg)

我得到[3]:

<coroutine object AuthMethods._start at 0x00000190D413F9C8>

以及[4]:

    C:\Users\user1\AppData\Local\Programs\Python\Python37\lib\site-packages\ipykernel_launcher.py:3: RuntimeWarning: coroutine 'MessageMethods.get_messages' was never awaited
  This is separate from the ipykernel package so we can avoid doing imports until

      3 msgs = client.get_messages(channel_username, limit=100)
----> 4 for msg in msgs.data:
      5     if msg.media is not None:
      6         client.download_media(message=msg)

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

Answer 1

如果msgs是一个协同例程，则需要等待它。因此循环之前的行可能应该是 msgs = wait client.get_messages(channel_username, limit=100)
