在 discord.py-rewrite 中将 Dm 发送给用户命令

Question

所以，我试图制作一个 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 将向消息的作者发送一条消息，询问 - “”谁你要dm吗到 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)

这段代码在heroku中打印出这个错误-

任何帮助将不胜感激！

Answer 1

因此，理想情况下，您应该在命令中获取用户输入。 wait_for 会让您头疼，尽管您似乎有些尝试这样做。这是一种简单的方法，您可以使用一些代码向被提及的人发送消息。

@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.||")

所以本质上，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，这是发送我们消息的人。使用: discord.User 仅仅意味着 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。 这里要了解的第二件事是*, value 的用法。简单来说，这意味着在您提及用户之后出现的任何内容都将被放入value 变量的字符串中。你可以阅读更多关于here背后的逻辑

在此之后，您可以根据需要简单地完成您的代码。希望对您有所帮助！
