试图做一个不和谐的机器人与discord.py，获取错误

我试图让机器人每隔几秒钟发送一条消息从一组预定义的消息。试图做一个不和谐的机器人与discord.py，获取错误

import discord 
import asyncio 
import random 

client = discord.Client() 

async def background_loop(): 
    await client.wait_until_ready() 
    while not client.is_closed: 
     channel = client.get_channel("channel id here") 
     messages = ["Hello!", "How are you doing?", "Howdy!"] 
     await client.send_message(channel, random.choice(messages)) 
     await asyncio.sleep(120) 

client.loop.create_task(background_loop()) 
client.run("discord token here")

但是，当我尝试运行它，我得到这个错误在控制台中，并没有消息发送到聊天。

/usr/bin/python3.5 /root/PycharmProjects/untitled/Loop.py 
Task exception was never retrieved 
future: <Task finished coro=<background_loop() done, defined at /root/PycharmProjects/untitled/Loop.py:8> exception=InvalidArgument('Destination must be Channel, PrivateChannel, User, or Object. Received NoneType',)>

    await client.send_message(channel, random.choice(messages))

获得信道对象解决了这个'discord.errors.InvalidArgument：目标必须是通道，PrivateChannel，用户或对象。收到NoneType' 检查您要将您的请求发送到哪里 - 确保您拥有正确的频道ID？ – CynePhoba12

你似乎是正确的，问题是我认为频道ID指的是频道的名称。现在全部修好了。 – Museman

我写一个辅助函数从客户端

def get_channel(channels, channel_name): 
    for channel in client.get_all_channels(): 
     print(channel) 
     if channel.name == channel_name: 
      return channel 
    return None 

client = discord.Client() 
general_channel = get_channel(client.get_all_channels(), 'general') 
await client.send_message(general_channel, 'test msg')
