Python discord.errors.ClientException:已连接到语音频道

因此，我用discord.py编写了一段代码，当用户加入语音频道时，它会播放音频文件。问题是我得到了上面的警告。我认为这是因为当机器人加入时，它看到自己加入了，不能再加入了。我试图用注释过的代码行来解决这个问题，但这似乎不起作用。完整错误将位于代码下方。我将只粘贴我的bot的这方面所需的代码，因为问题在于这段代码，而不是其余部分。我也收到这个websocket关闭警告，但不知道它是否重要

代码：

@bot.event
async def on_voice_state_update(member: discord.Member, before, after):
    vc_before = before.channel
    vc_after = after.channel
    path_mp3 = "Tutturuu.mp3"
    path_ffmpeg = r"C:\ffmpeg\bin\ffmpeg.exe"
    if vc_before == vc_after:
        return
    if vc_before is None:  # and member.display_name != discord.ClientUser.name:
        channel = member.voice.channel
        vc = await channel.connect()
        time.sleep(.5)
        vc.play(discord.FFmpegPCMAudio(executable=path_ffmpeg, source=path_mp3))
        with audioread.audio_open(path_mp3) as f:
            time.sleep(f.duration)
        await vc.disconnect()
    elif vc_after is None:
        return
    else:
        channel = member.voice.channel
        vc = await channel.connect()
        time.sleep(.5)
        vc.play(discord.FFmpegPCMAudio(executable=path_ffmpeg, source=path_mp3))
        with audioread.audio_open(path_mp3) as f:
            time.sleep(f.duration)
        await vc.disconnect()

完全错误： 正在忽略语音状态更新中的异常 回溯（最近一次呼叫最后一次）： 文件“C:\Users\yorbe\OneDrive\Documenten\Folders\Gerbinbot\u 3000\venv\lib\site packages\discord\client.py”，第333行，在运行事件中 等待coro（*args，**kwargs） 文件“C:/Users/yorbe/OneDrive/Documenten/Folders/Gerbinbot\u 3000/main.py”，第109行，处于语音更新状态 vc=等待通道。连接（） 文件“C:\Users\yorbe\OneDrive\Documenten\Folders\Gerbinbot\u 3000\venv\lib\site packages\discord\abc.py”，第1115行，在connect中 引发ClientException（'已连接到语音频道'） discord.errors.ClientException:已连接到语音频道。 websocket连接正在关闭。 websocket连接正在关闭。

websocket连接正在关闭。

好的，我自己找到了解决方法。如果vc_before==vc_after，只需在前面添加此代码（请参见页眉之间）

@bot.event
async def on_voice_state_update(member: discord.Member, before, after):
     vc_before = before.channel
    vc_after = after.channel
    path_mp3 = "Tutturuu.mp3"
    path_ffmpeg = r"C:\ffmpeg\bin\ffmpeg.exe"
    -----------------
    for role in member.roles:
        if role.name == "Name of the role that your bot made when it joined the server, 
usually its own name":
            return
    -----------------
    if vc_before == vc_after:
        return
    if vc_before is None:
        channel = member.voice.channel
        vc = await channel.connect()
        time.sleep(.5)
        vc.play(discord.FFmpegPCMAudio(executable=path_ffmpeg, source=path_mp3))
        with audioread.audio_open(path_mp3) as f:
            time.sleep(f.duration)
        await vc.disconnect()
    elif vc_after is None:
        return
    else:
        channel = member.voice.channel
        vc = await channel.connect()
        time.sleep(.5)
        vc.play(discord.FFmpegPCMAudio(executable=path_ffmpeg, source=path_mp3))
        with audioread.audio_open(path_mp3) as f:
            time.sleep(f.duration)
        await vc.disconnect()
