问题描述
我注意到,当我从 discord.py Github 页面运行代码片段时,它没有显示预期的消息.
I noticed that when I ran a code snippet from the discord.py Github page it didn't show the intended message.
我稍作修改的代码:
import discord import asyncio import nest_asyncio nest_asyncio.apply() class MyClient(discord.Client): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # create the background task and run it in the background self.bg_task = self.loop.create_task(self.my_background_task()) async def on_ready(self): print('Logged in as') print(self.user.name) print(self.user.id) print('------') async def my_background_task(self): counter = 0 channel = self.get_channel(1234567890) # channel ID goes here while not self.is_closed(): counter += 1 await channel.send(counter) await asyncio.sleep(10) # task runs every 10 seconds client = MyClient() client.run('token')
当我检查 Discord 时没有显示任何内容,但它确实在 IDLE 中显示输出:
When I check Discord nothing shows, however it does show output in the IDLE:
Logged in as bot_name 1234567890 ------
但在 Discord 服务器中,什么也没有发生.有没有办法解决这个问题?
But in the Discord server, nothing happens. Is there anyway to fix this?
推荐答案
代码失败,因为 self.get_channel(1234567890) 在 bot 正确连接之前使用,导致它总是返回 无.这是因为先完成client = MyClient(),即后台任务已创建但bot尚未连接,这是通过client.run完成的.
The code fails because self.get_channel(1234567890) is used before the bot has properly connected, resulted in it always returning None. This is because client = MyClient() is done first, meaning the background task is created but the bot has not yet connected, which is done through client.run.
要解决此问题,请将循环的创建移至 on_ready 事件内部.
To fix this, move the creation of the loop to inside the on_ready event.
import discord import asyncio import nest_asyncio nest_asyncio.apply() class MyClient(discord.Client): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) async def on_ready(self): print('Logged in as') print(self.user.name) print(self.user.id) print('------') # create the background task and run it in the background self.bg_task = self.loop.create_task(self.my_background_task()) async def my_background_task(self): counter = 0 channel = self.get_channel(1234567890) # channel ID goes here while not self.is_closed(): counter += 1 await channel.send(counter) await asyncio.sleep(10) # task runs every 10 seconds client = MyClient() client.run('token')
