Python discord bot 离开语音频道

Question

我已经让机器人加入我的语音服务器，如下所示

 if message.content.startswith("?join"):

    channel = message.author.voice.channel

    await channel.connect()

    await message.channel.send('bot joined')

但我不能让机器人离开频道..我该如何编写代码来做到这一点？和有什么区别

@bot.event

 async def on_message(message):

 if message.content.startswith('~'):

和

@bot.command()

async def ~(ctx):

您可以通过两种方式执行这两个命令（加入和离开频道命令），一种是使用 on_message，另一种是使用@bot.commands。最好使用 bot.command 而不是 on_message 作为命令，因为 bot.commands 具有更多功能，而且我认为它是为命令而构建的，它的速度很快。因此，我将使用 bot.command 重写您的两个命令，并在此处使用 on_message 以防您不想使用 bot.command。根据您的消息，我假设?是您的前缀使用[e-mail] def on_message(message):    if (message.content.startswith('?join')):        if (message.author.voice): # If the person is in a channel            channel = message.author.voice.channel            await channel.connect()            await message.channel.send('Bot joined')        else: #But is (s)he isn't in a voice channel            await message.channel.send("You must be in a voice channel first so I can join it.")    elif message.content.startswith('?~'): # Saying ?~ will make bot leave channel        if (message.guild.voice_client): # If the bot is in a voice channel             await message.guild.voice_client.disconnect() # Leave the channel            await message.channel.send('Bot left')        else: # But if it isn't            await message.channel.send("I'm not in a voice channel, use the join command to make me join")    await bot.process_commands(message) # Always put this at the bottom of on_message to make commands work properly使用[e-mail]()async def join(ctx):    if (ctx.author.voice): # If the person is in a channel        channel = ctx.author.voice.channel        await channel.connect()        await ctx.send('Bot joined')    else: #But is (s)he isn't in a voice channel        await ctx.send("You must be in a voice channel first so I can join it.")@bot.command(name = ["~"])async def leave(ctx): # Note: ?leave won't work, only ?~ will work unless you change  `name = ["~"]` to `aliases = ["~"]` so both can work.    if (ctx.voice_client): # If the bot is in a voice channel         await ctx.guild.voice_client.disconnect() # Leave the channel        await ctx.send('Bot left')    else: # But if it isn't        await ctx.send("I'm not in a voice channel, use the join command to make me join")

保存通道连接，以便稍后断开连接。voice = None...    if message.content.startswith("?join"):        channel = message.author.voice.channel        global voice = await channel.connect()        await message.channel.send('bot joined')    elif message.content.startswith("?join"):        await self.voice.disconnect()无论如何，尝试使用discord.ext.commands扩展。它使所有涉及命令的事情变得更容易。我还建议使用 cogs ( example )，因为您可以拥有一个包含所有与语音相关的类，并且您不需要全局变量。
