Question

我正在制作一个可以在 vc 中播放声音的机器人。我已经编写了加入通话、播放 mp3、然后离开通话的代码，但是当用户不在通话中时，我收到此错误：

Ignoring exception in command ring:
Traceback (most recent call last):
  File "C:\Users\max\AppData\Roaming\Python\Python39\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\max\OneDrive\Desktop\Code\DiscordBots\Nokia\Nokia.py", line 91, in ring
    channel = ctx.author.voice.channel
AttributeError: 'NoneType' object has no attribute 'channel'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\max\AppData\Roaming\Python\Python39\site-packages\discord\ext\commands\bot.py", line 903, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\max\AppData\Roaming\Python\Python39\site-packages\discord\ext\commands\core.py", line 859, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\max\AppData\Roaming\Python\Python39\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'NoneType' object has no attribute 'channel'

这是我迄今为止的代码：

@client.command()
async def ring(ctx):
    channel = ctx.author.voice.channel
    vc = await channel.connect()
    vc.play(discord.FFmpegPCMAudio("Audio/NokiaRingtone.mp3"))
    time.sleep(5)
    await ctx.voice_client.disconnect()

还有一件事；我想知道为什么当我的机器人与 vc 断开连接时我在聊天中得到这些：

websocket connection is closing.
websocket connection is closing.
websocket connection is closing.

如果有人能帮我检查用户是否在语音频道中并告诉我为什么我在控制台中看到这三行，那就太好了。

您可以使用 if 语句简单地检查它是否不是无类型

@bot.command()
async def foo(ctx):
    voice_state = ctx.member.voice

    if voice_state is None:
        # Exiting if the user is not in a voice channel
        return await ctx.send('You need to be in a voice channel to use this command')

    # Put the rest of the code here

检查用户是否在语音频道 discord.py
