TypeError: on_voice_state_update() 需要 2 个位置参数

Question

我正在尝试制作一个机器人，让成员在语音频道上扮演角色，但由于某种原因它不起作用。这是代码：@client.eventasync def on_voice_state_update(before, after):    role = discord.utils.get(after.server.roles, name="glosowy")    if not before.voice.voice_channel and after.voice.voice_channel:        await client.add_roles(after, role)    elif before.voice.voice_channel and not after.voice.voice_channel:        await client.remove_roles(after, role)这是我收到的错误：Ignoring exception in on_voice_state_updateTraceback (most recent call last):  File "C:\Users\aaa\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\client.py", line 312, in _run_event    await coro(*args, **kwargs)TypeError: on_voice_state_update() takes 2 positional arguments but 3 were given

Answer 1

你忘记了参数'member'

从文档

async def on_voice_state_update(member, before, after)

之前和之后是 VoiceState，代表成员（在参数中）是否静音、广播等信息……

因此你不能从中检索角色你必须从成员那里得到它

@client.event

async def on_voice_state_update(member, before, after):

    role = discord.utils.get(member.guild.roles, name="glosowy")

    if role: # verify their is a role with that name

        if not before.channel and after.channel: # check member just entered a channel

            await member.add_roles(role) #add role to it 

        elif before.channel and not after.channel: # check member just left a channel

            await member.remove_roles(role) # remove role to it
