一个不和谐的机器人命令使其他命令不起作用

import asyncio
import discord

client = discord.Client()


token = "########################"


@client.event
async def on_ready():
    print("Logged in as ") 
    print(client.user.name)
    print("===========")

@client.event
async def on_message(message):
    if message.content.lower().startswith('!디엠 '):
        if (str(message.author.id) != "451744624965582848"):
            await message.channel.send(":no_entry_sign:  최고 관리자만 전체 DM을 요청할 수 있어요.")
            return None

        DM내용 = message.content.lower()[4:]
        for guild in client.guilds:
            members = guild.members
            for member in members:
                if member.bot is True:
                    continue
                channel = await member.create_dm()
                embed = discord.Embed(title='???????????? ???????????????? 전체 공지', color = FFFF33)
                embed.add_field(name='???????????? ????????????????에서 발송된 DM입니다.', value=DM내용, inline=False)

                await channel.send(embed=embed)
        await message.channel.send('메세지가 성공적으로 전달되었어요.')

    await client.process_commands(message)

@client.event
async def on_member_join(member):
    embed = discord.Embed(title='환영합니다', colour = discord.Colour.blue())
    embed.add_field(name=f'{member.name}님, OWS SHOP의 모든 제품을 마음껏 둘러보세요!', value="모든 구매 문의는 <@451744624965582848>에게 주시면 감사하겠습니다.", inline=False)
    embed.set_footer(text="OWS SHOP 인사봇")
    await client.get_channel(717379135609110615).send(embed=embed)

@client.event

    embed.add_field(name=f'{member.name}님이 나가셨어요.', value="다음에 또 와주시면 감사하겠습니다!", inline=False)
    embed.set_footer(text="OWS SHOP 인사봇")
    await client.get_channel(717379135609110615).send(embed=embed)

@client.event
async def on_message(message):
    if (str(message.channel.id) == "717379135835603005"):
        if (message.content.find("@everyone") != -1):
            await message.delete()
            await message.channel.send(":no_entry_sign:  <@"+str(message.author.id)+">님, 중고장터에서는 everyone을 사용하실 수 없어요.")

        else:
            if (message.content.find("@here") != -1):
                await message.delete()
                await message.channel.send(":no_entry_sign:  <@"+str(message.author.id)+">님, 중고장터에서는 here을 사용하실 수 없어요.")


client.run(token)

我使用 Discord.py 制作了“DM ALL USERS IN SERVER”和“欢迎，再见消息”和“检测每个人或此处并删除和警告”机器人。 “检测所有人或此处并删除并警告”功能有效，但“DM ALL USERS IN SERVER”功能无效。

@client.event
async def on_message(message):
    if (str(message.channel.id) == "717379135835603005"):
        if (message.content.find("@everyone") != -1):
            await message.delete()
            await message.channel.send(":no_entry_sign:  <@"+str(message.author.id)+">님, 중고장터에서는 everyone을 사용하실 수 없어요.")

        else:
            if (message.content.find("@here") != -1):
                await message.delete()
                await message.channel.send(":no_entry_sign:  <@"+str(message.author.id)+">님, 중고장터에서는 here을 사용하실 수 없어요.")

这部分效果很好，但是

async def on_message(message):
    if message.content.lower().startswith('!디엠 '):
        if (str(message.author.id) != "451744624965582848"):
            await message.channel.send(":no_entry_sign:  최고 관리자만 전체 DM을 요청할 수 있어요.")
            return None

        DM내용 = message.content.lower()[4:]
        for guild in client.guilds:
            members = guild.members
            for member in members:
                if member.bot is True:
                    continue
                channel = await member.create_dm()
                embed = discord.Embed(title='???????????? ???????????????? 전체 공지', color = FFFF33)
                embed.add_field(name='???????????? ????????????????에서 발송된 DM입니다.', value=DM내용, inline=False)
                embed.set_footer(text="OWS SHOP DM봇")
                await channel.send(embed=embed)
        await message.channel.send('메세지가 성공적으로 전달되었어요.')

    await client.process_commands(message)

这部分效果不好。

@client.event
async def on_message(message):
    if (str(message.channel.id) == "717379135835603005"):
        if (message.content.find("@everyone") != -1):
            await message.delete()
            await message.channel.send(":no_entry_sign:  <@"+str(message.author.id)+">님, 중고장터에서는 everyone을 사용하실 수 없어요.")

        else:
            if (message.content.find("@here") != -1):
                await message.delete()
                await message.channel.send(":no_entry_sign:  <@"+str(message.author.id)+">님, 중고장터에서는 here을 사용하실 수 없어요.")

如果我删除这部分，(!디엠) 效果会很好。什么是问题？

Answer 1

在 on_message 事件的最后，添加 await client.process_commands(message)

Answer 2

当您使用discord.Client() 时，您的代码中每个事件只能有一个。没有必要有多个——你可以在多个事件中做的任何事情，你也可以在一个事件中做。使用if/elif 语句。

如果您确实包含多个事件，则最近定义/注册的事件将是“活动”事件。

我建议研究使用命令装饰器创建命令，因为这比将它们全部塞进on_message 事件中要方便得多；

@client.command(name="디엠") # the string contents is what the command will be in discord
async def mycmd(ctx): # try to avoid having non-ASCII characters as identifiers
    if ctx.author.id != 451744624965582848: # IDs are ints in rewrite, no need to convert to str
        await ctx.send(":no_entry_sign:  최고 관리자만 전체 DM을 요청할 수 있어요.")
    else:
        # rest of the command's code

@client.command()
async def othercmd(ctx): # same concept applies if you want multiple commands
    # some more code here

@client.event
async def on_message(message):
    await client.process_commands(message)
    if message.channel.id == 717379135835603005: # same deal here with the IDs
        # rest of the code
    elif other_expression == "something else":
        # do some other stuff
    # etc.
