如何限制仅命令作者使用Discord帮助选择菜单并添加时限

针对你的需求，我们可以通过两个关键修改实现目标：

1. 限制仅/help命令的调用者可操作菜单 #

在DropdownView中保存命令调用者的用户ID，通过重写interaction_check方法，全局验证操作菜单的用户是否为原调用者。

2. 添加菜单使用时限 #

初始化View时设置timeout参数，并重写on_timeout方法，在超时后自动禁用菜单并更新提示。

class Dropdown(discord.ui.Select):
    def __init__(self):
        options = [
            discord.SelectOption(label='General', value="1", description='Provides you with general commands and information about them.', emoji='1️⃣'),
            discord.SelectOption(label='Moderation', value="2", description='Provides you with moderation commands and information about them.', emoji='2️⃣'),
        ]
        super().__init__(placeholder='Choose what type of help you need below.', min_values=1, max_values=1, options=options)

        if self.values[0]=="2":
            await interaction.response.edit_message(embed=moderationEmbed)

class DropdownView(discord.ui.View):
    def __init__(self, author_id: int, timeout: float = 300.0):
        # timeout设置为300秒（5分钟），可根据需求调整
        super().__init__(timeout=timeout)
        self.author_id = author_id
        self.add_item(Dropdown())

    async def interaction_check(self, interaction: discord.Interaction) -> bool:
        # 验证操作用户是否为命令调用者
        if interaction.user.id != self.author_id:
            await interaction.response.send_message("你无权操作这个菜单！", ephemeral=True)
            return False
        return True

    async def on_timeout(self) -> None:
        # 超时后禁用所有组件并更新消息提示
        for item in self.children:
            item.disabled = True
        # 获取原消息并更新
        if self.message:
            embed = self.message.embeds[0]
            embed.description = "帮助菜单已超时，无法继续操作。如需帮助请重新调用`/help`命令。"
            await self.message.edit(embed=embed, view=self)

class Bot(commands.Bot):
    def __init__(self):
        intents = discord.Intents.default()
        intents.message_content = True
        super().__init__(command_prefix=commands.when_mentioned_or('k!'), intents=intents)

    async def on_ready(self):
        print('hi')

bot = Bot()

@bot.tree.command(name="help", description="Provides you with a help embed.")
async def _help(interaction):
    embed=discord.Embed(title="Help Menu", description="To find the help you're looking for, look below in this embed for whatever you need help with!", color=0xFF5349)
    embed.set_footer(text="Made by justin;#6868")

    # 传入调用者ID给View
    view = DropdownView(author_id=interaction.user.id)
    # 发送消息后保存消息引用到View，方便超时后编辑
    message = await interaction.response.send_message(embed=embed, view=view, ephemeral=True)
    view.message = await message.original_response()

关键修改说明 #

• 权限验证：在DropdownView的interaction_check方法中，对比操作用户ID与命令调用者ID，非调用者操作时返回错误提示并拒绝执行。
• 时限设置：初始化DropdownView时传入timeout参数（单位秒），超时后触发on_timeout方法，禁用所有组件并更新消息提示。
• 消息引用保存：发送消息后获取原消息对象并赋值给view.message，确保超时后能正确编辑消息。
