Python Discord.py bot+；夸特：尝试连接到语音频道总是会给出一个“提示”；任务已将future附加到另一个循环“中”；

我一直在尝试创建一个discord机器人，它可以通过web界面接收命令。我将discord.py用作discordapi包装器，将Quart用作REST框架，因为我需要处理异步任务，而Flask不支持它们

现在我有两个文件：

app.py

    vc = await voiceChannel.connect()

    vc.play(discord.FFmpegPCMAudio(source="audio\{}".format(audio_name), executable=FFMPEG_PATH))
    while vc.is_playing():
        time.sleep(.1)
    await vc.disconnect()

async def get_online_voice_members():
    guild = bot.get_guild(NMC_GUILD_ID)
    online_voice_users = {}
    for voiceChannel in guild.voice_channels:
        for user in voiceChannel.members:
            online_voice_users[user] = voiceChannel
    return online_voice_users

wait discord。播放音频（“goodnight.mp3，members[user]）

我想我没有正确理解asyncio库是如何工作的，因为在我看来，无论我做什么尝试，app.py中的行

vc=wait voiceChannel.connect（）

总是在与主循环不同的循环上运行。我缺少什么吗？

这是因为您在导入时启动了discord客户端（app.py的第3行）。这样做意味着它将使用导入时可用的事件循环。但是，Quart（和Hypercorn，除非被告知不要太多）将关闭现有循环并在启动时创建一个新循环。因此，我建议使用该功能进行初始化

为了解决这个问题，我将把你的discord命令包装在一个类中，并在启动函数中初始化它。请注意，我喜欢将实例存储在应用程序本身上（这样就可以通过

当前应用程序

代理访问它们），但这并不是必需的。例如

app.py

import discord

bot = discord.Client(intents=discord.Intents.all())

...

async def play_audio(audio_name, voiceChannel):
    vc = await voiceChannel.connect()
    print("test")
    vc.play(discord.FFmpegPCMAudio(source="audio\{}".format(audio_name), executable=FFMPEG_PATH))
    while vc.is_playing():
        time.sleep(.1)
    await vc.disconnect()

async def get_online_voice_members():
    guild = bot.get_guild(NMC_GUILD_ID)
    online_voice_users = {}
    for voiceChannel in guild.voice_channels:
        for user in voiceChannel.members:
            online_voice_users[user] = voiceChannel
    return online_voice_users
