将Dm发送到discord.py-rewrite中的用户命令

Question

所以，我正在尝试创建一个DM命令，询问我们想要将DM消息(值)发送给哪个用户，ex- !vx dm THIS IS THE CONTENT OF THE MESSAGE会向消息的作者发送一条消息，询问-“”您想要dm给谁？“而作者将通过提及他想要将DM发送给谁的人来回复，在这样做之后，它会将DM发送给用户，然后发送一条消息，说”我已将消息发送到X“。这就是我希望命令是这样的。

@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)

这段代码在heroku中打印出这个错误-

因此，理想情况下，您应该在命令中获取用户输入。这将为您省去使用wait_for的麻烦，尽管您似乎已经尝试过这样做。这是一个简单的方法，您可以使用一些代码向提到的任何人发送消息。

@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，这里有几件事需要理解。首先，我们正在解析一个user: discord.User参数，这是我们要发送消息的人。使用: discord.User只是意味着D.py会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。这里要理解的第二件事是*, value的用法。简单地说，这意味着您提到用户之后出现的任何内容都将被放入value变量的字符串中。您可以阅读有关该here背后的逻辑的更多信息

在此之后，您可以简单地完成您想要的代码。我希望这对你有帮助！
