Question

因此，我试图创建一个DM命令，询问我们要将DM消息（值）发送给哪个用户，例如!vx dm THIS IS THE CONTENT OF THE MESSAGE会向该消息的作者发送一条消息，询问- “您要向谁发送dm？”，作者将通过提及要向其发送dm的人进行回复，然后将其发送给用户，然后发送一条消息，说“我已经发送了dm”。消息发送到X”。这就是我想要的命令。

@client.command()
async def dm(ctx, value):
    member = discord.Member if not discord.Member else discord.Member
    await ctx.send(f"{ctx.author.mention}, Whom do you want to send the message to?")
    def check(m):
        return m.content == member.mention == member
    await ctx.member.send(f"**{value}**")
    await ctx.member.send(f"||Sent by {ctx.author.mention} via VX Helper.||")
    e = discord.Embed(title=f"Message sent to {member.display_name}.", description=f"Message Content - {value}.", colour=0x40cc88)
    e.set_footer(text=f"Sent by {ctx.author.display_name}", icon_url=ctx.author.avatar_url)
    await ctx.channel.purge(limit=3)
    await ctx.send(embed=e)

此代码在heroku中打印出此错误-

因此，理想情况下，您应该尝试在命令内获取用户输入。尽管看起来似乎有些尝试，但这会为您节省wait_for的麻烦。这是让您使用一些代码向任何提及的人发送消息的简单方法。

@bot.command()
async def dm(ctx, user: discord.User, *, value):
    # Send a message to the mentioned user!
    await user.send(f"**{value}**")
    await user.send(f"||Sent by {ctx.author.display_name} via VX Helper.||")

因此，从本质上讲，这里有两点要理解。首先，我们正在解析一个user: discord.User参数，这是向其发送消息的人。使用: discord.User只是意味着D.py将自动将其转换为有效用户，因此我们可以直接发送到该对象。这里要了解的第二件事是*, value的用法。简单来说，这意味着您提到用户后出现的所有内容都将放入value变量的字符串中。您可以详细了解here

背后的逻辑

此后，您可以根据需要简单地完成代码。希望对您有所帮助！
