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):

Answer 1

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构建的，所以速度很快。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on_message

@bot.event
async 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bot.command

@bot.command()
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")

保存频道连接，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，请尝试使用 discord.ext.commands 扩展名。它使所有涉及命令的事情变得更容易。我还建议使用 cogs (example)，因为您可以创建一个包含所有与语音相关的类，并且不需要全局变量。
