如何使用discord.py消除DM中的反应

我想删除我的机器人发送的私人消息中的反应。当我尝试这个时：

    embed = discord.Embed(title="Choose the word difficulty.",description="**1.** Easy\n**2.** Medium\n**3.** Hard\n**4.** Ridiculous",color=0x7a17bb)
    msg = await client.send_message(MAYOR_TAKEN[0],embed=embed)
    await client.add_reaction(message=msg,emoji='\u0031\u20E3')
    await client.add_reaction(message=msg,emoji='\u0032\u20E3')
    await client.add_reaction(message=msg,emoji='\u0033\u20E3')
    await client.add_reaction(message=msg,emoji='\u0034\u20E3')
    while True:
        react = await client.wait_for_reaction(emoji=None,message=msg,check=check)
        if react.reaction.emoji == '\u0031\u20E3':
            await client.delete_message(message=msg)
            await choosewords(1)
        elif react.reaction.emoji == '\u0032\u20E3':
            await client.delete_message(message=msg)
            await choosewords(2)
        elif react.reaction.emoji == '\u0033\u20E3':
            await client.delete_message(message=msg)
            await choosewords(3)
        elif react.reaction.emoji == '\u0034\u20E3':
            await client.delete_message(message=msg)
            await choosewords(4)
        else:
            await client.remove_reaction(message=msg,emoji=react.reaction.emoji,member=react.user)

我收到 FORBIDDEN (status code: 403): Cannotexecaction on a DM Channel 从await client.remove_reaction(message=msg,emoji=react.reaction.emoji,member=react.user)。我怎样才能消除这种反应？

Edit:

  Traceback (most recent call last)

    raise Forbidden(r, data)
discord.errors.Forbidden: FORBIDDEN (status code: 403): Cannot execute action on a DM channel

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\samue\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\ext\commands\bot.py", line 846, in process_commands
    yield from command.invoke(ctx)

    raise CommandInvokeError(e) from e
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: Forbidden: FORBIDDEN (status code: 403): Cannot execute action on a DM channel

据我所知，不可能消除在 DM 通道中发送的消息中其他人的反应。根据评论中的建议，建议删除消息并重新发送并添加反应。

Code:

async def send_reaction(ctx: commands.Context):
   msg = await ctx.send("Hello")
   await msg.add_reaction("ur reaction")
   try:
       await bot.wait_for("reaction_add", check=lambda r, u: u.id == ctx.author.id, timeout=60.0) # seconds
   except asyncio.TimeoutError:
       await ctx.send("Timed out")
   else:
       await msg.delete()
       msg = await ctx.send("Hello")
       await msg.add_reaction("ur reaction")

此实现删除旧消息并重新发送新消息。尽管这并没有处理 DM 通道并将其应用于每个通道。您可以检查channel.type以仅将其应用于DM通道并使用msg.remove_reaction()来删除反应。

希望这对您有所帮助，谢谢！
