Discord VC配置按钮异常及Kick功能替代方案咨询

你的问题根源是点击Lock按钮后，通过send_message发送了新消息，但原嵌入消息的View没有被更新，导致View实例的交互会话结束，后续点击其他按钮时触发"interaction failed"。

修复方案 #

修改Lock和Unlock按钮的逻辑，点击后更新原消息的View状态（禁用/启用其他按钮），并通过edit_message修改原消息，而不是发送新消息：

class VCView(ui.View):
    def __init__(self):
        # 设置timeout=None让View永久有效（需开启组件持久化，按需调整）
        super().__init__(timeout=None)

    @ui.button(label="Lock", style=discord.ButtonStyle.primary)
    async def lock_vc(self, interaction:discord.Interaction, button: discord.ui.Button):
        voice_channel = interaction.user.voice.channel
        canned = discord.Embed(description="Voice channel locked.",color=discord.Color.random())
        await voice_channel.set_permissions(interaction.guild.default_role, connect=False)
        
        # 禁用除Lock外的所有按钮
        for btn in self.children:
            if btn != button:
                btn.disabled = True
        
        # 更新原消息的嵌入和View
        await interaction.response.edit_message(embed=canned, view=self)

    @ui.button(label="Unlock", style=discord.ButtonStyle.primary)
    async def unlock_vc(self, interaction:discord.Interaction, button: discord.ui.Button):
        voice_channel = interaction.user.voice.channel
        chan = discord.Embed(description="Voice channel unlocked.",color=discord.Color.random())
        await voice_channel.set_permissions(interaction.guild.default_role, connect=True)
        
        # 重新启用所有按钮
        for btn in self.children:
            btn.disabled = False
        
        # 更新原消息的嵌入和View
        await interaction.response.edit_message(embed=chan, view=self)

    @ui.button(label="Rename", style=discord.ButtonStyle.primary)
    async def rename_vc(self, interaction:discord.Interaction, button: discord.ui.Button):
        await interaction.response.send_modal(RenameModal())

对于需要member参数的Kick功能，推荐以下两种更高效的实现：

1. 斜杠命令（Slash Command） #

直接创建带成员参数的斜杠命令，用户可直接指定目标成员，体验更直观：

@bot.tree.command(name="kick", description="从当前语音频道踢出成员")
async def kick_member(interaction: discord.Interaction, member: discord.Member, reason: str = "无理由"):
    # 检查用户是否在语音频道且有权限
    if not interaction.user.voice:
        await interaction.response.send_message("你不在任何语音频道中", ephemeral=True)
        return
    
    vc = interaction.user.voice.channel
    if not vc.permissions_for(interaction.user).kick_members:
        await interaction.response.send_message("你没有权限在此频道踢人", ephemeral=True)
        return
    
    await vc.kick(member, reason=reason)
    embed = discord.Embed(description=f"已将 {member.mention} 踢出语音频道，理由：{reason}", color=discord.Color.random())
    await interaction.response.send_message(embed=embed)

2. 上下文菜单（Context Menu） #

给用户添加右键菜单选项，点击后直接触发踢人操作，无需手动输入成员：

@bot.tree.context_menu(name="从我的VC踢出")
async def kick_from_vc(interaction: discord.Interaction, member: discord.Member):
    if not interaction.user.voice:
        await interaction.response.send_message("你不在任何语音频道中", ephemeral=True)
        return
    
    vc = interaction.user.voice.channel
    if not vc.permissions_for(interaction.user).kick_members:
        await interaction.response.send_message("你没有权限在此频道踢人", ephemeral=True)
        return
    
    await vc.kick(member)
    await interaction.response.send_message(f"已将 {member.mention} 踢出你的语音频道", ephemeral=True)
