Discord.py 文本通道检查

Question

@client.command(aliases=["logchannel, setlog"])

@commands.has_permissions(manage_messages=True)

async def log(ctx, *args: discord.TextChannel):

    with open("configs/channels.json", "r") as f:

        channels = json.load(f)

    channel = channels.get(str(ctx.guild.id), ctx.channel.id)

    if len(args) == 0:

        await ctx.send("Which channel should I set the logs? :thinking:")

    elif args[0] != discord.TextChannel:

        await ctx.send("That is not a valid channel!")

    elif args[0] == discord.TextChannel:

        with open("configs/channels.json", "w") as f:

            json.dump(channels, f, indent=4)

        embed = discord.Embed(title="Log channel set! :white_check_mark:",

                              description=f"**{channel}** has been set as logs channel!",

                              color=0x2f3136)

        await ctx.send(embed=embed)

所以我的这部分代码是为使用 JSON 设置日志通道而制作的。json 部分工作正常，因为我在其他几个命令中使用过它。但它看不到是否提供了有效的频道。据我所知，它应该是，discord.TextChannel但事实并非如此。该if len(args) == 0部分有效，但其他部分无效。我怎样才能使这项工作？我应该放什么而不是discord.TextChannel？

Answer 1

一种更精确的方法是使用TextChannelConverter它在提供 ID/名称/提及时返回通道，而不仅仅是名称from discord.ext import commandsasync def log(ctx, *, args=None):    if not args:        await ctx.send("Please provide the channel to set the logs")        return    try:        channel = await commands.TextChannelConverter().convert(ctx, args)    except:        return await ctx.send("Channel Not Found")    #channel is not a TextChannel object, save its ID or send or whatever you want to do

Answer 2

我认为它可以基于此工作。    @commands.command()    async def test(self, ctx, channel=None):        channel2 = self.client.get_channel(id=int(channel))        if type(channel2) != discord.channel.TextChannel:            await ctx.send('Please do not enter an audio channel')        else:            await ctx.send('Perfect.')

Return 只是结束您可以使用它而不是 if 语句的函数。我不知道使用的是什么 JSON 文件，我希望这会有所帮助async def log(ctx, *, args=None):    if not args:        await ctx.send("Which channel should I set the logs? :thinking:")        return    for channel in ctx.guild.channels:        if channel.name == args:            await ctx.send('Found your channel')            # channel is now an object, you can do what you want here            await channel.send('This is the channel wanted')            return    await ctx.send("Can't find your channel")
