我试图让机器人每隔几秒钟从一组预定义的消息中发送消息。
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,当我尝试运行它时,我在控制台中收到此错误,并且没有消息发送到聊天中。
/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',)>

raise InvalidArgument(fmt.format(destination))

答案 0 :(得分:0)
我通过编写辅助函数来修复此问题,以从客户端获取Channel对象
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')
