discord.py（重写）如何将命令使用能力缩小到单个通道？

Question

我正在尝试使此代码仅在特定频道中有效。当我尝试在正确的通道中执行命令时，它只会发送大量错误。如果你想测试它，我会添加我的导入。上次我试图问这个问题，但被拒绝了。我仍然不知道该怎么做，只需要一点帮助，因为我是编写 discord 机器人的新手。

import discord
from discord.ext import commands, tasks
import os
import random
import asyncio
from asyncio import gather    
        
client = commands.Bot(command_prefix='.')
        
@client.command()
    async def car(ctx):
            pictures = [

            channel = discord.utils.get()
            if channel == 705161333972140072:
                await ctx.channel.purge(limit=1)
                await ctx.send(f'{random.choice(pictures)}')
    
client.run('token')

Answer 1

您需要对命令功能进行一些更改：

修正缩进
使用ctx.channel.id代替channel和discord.utils.get()
不清除，而是删除命令消息

@client.command()
async def car(ctx):
    pictures = [
    'https://car-images.bauersecure.com/pagefiles/78294/la_auto_show_11.jpg',
    'http://www.azstreetcustom.com/uploads/2/7/8/9/2789892/az-street-custom-gt40-2_orig.jpg',

    ]
    if ctx.channel.id == 705161333972140072:
        await ctx.message.delete()
        await ctx.send(random.choice(pictures))

client.run('token')
