在 dm discord.py 中等待来自同一作者的消息

Question

当机器人加入时，我有一个设置服务器的功能，但我正在和我的朋友同时交谈并且它出现错误，因为我只希望机器人从 dm 读取消息

async def on_guild_join(guild):

    print("Bot added to server: " + guild.name)

    gid = str(guild.id)

    server = Server()

    server.name = guild.name
    server.discordId = guild.id
    server.ownerId = guild.id
    server.welcome_message = None
    server.lang = "en"
    # here goes another tons of values

    if guild.id in db['guilds']:
        pass
    else:
        servers_dic = db['guilds']
        servers_dic[gid] = server.toJSON()
        print(server.toJSON())
        db['guilds'] = servers_dic

    await guild.owner.send(f"Hi! Thanks for adding me to your server, {guild.name}! To start using me, we'll have to set up a few things. Do you want to do it now or later?\n\n(n/l)")

    msg = await bot.wait_for('message', check=lambda message: message.author == guild.owner)

    if msg.content.lower() in ['n', 'now']:

        server = deencoder(db['guilds'][gid])
        if isinstance(server, Server):
            print("Class created successfully!")
        print(server)

有什么办法吗？

Answer 1

您可以为该命令添加 @commands.dm_only() 装饰器，使其仅在 DM 频道中工作：

import discord
from discord.ext import commands

@bot.command()
@commands.dm_only()
async def something(ctx):
    #do something

或者您可以更改检查以检查消息是否在 DM 频道中发送：

msg = await bot.wait_for('message', check=lambda message: message.author == guild.owner and isinstance(message.channel, discord.DMChannel))

Answer 2

您可以简单地使用isinstance 函数并检查discord.DMChannel

def check(message):
    return message.author == guild.owner and isinstance(message.channel, discord.DMChannel)

msg = await bot.wait_for('message', check=check)

# or if you still want to use lambda expressions
msg = await bot.wait_for('message', check=lambda message: message.author == guild.owner and isinstance(message.channel, discord.DMChannel))
