您必须使用send_message方法。在此之前，你必须找到哪个User对应于你自己。

@client.event
async def on_message(message):
    # we do not want the bot to reply to itself
    if message.author == client.user:
        return

    # can be cached...
    me = await client.get_user_info('MY_SNOWFLAKE_ID')
    await client.send_message(me, "Hello!")

@client.event
async def on_message(message):
    if message.content.startswith("#whatever you want it to be")
        await client.send_message(message.author, "#The message")

用你想要的单词替换那些带标签的东西。例如：“无论你想成为什么，它都可能是”！#消息可以是“命令是...”。

对于任何新的：

格式：

dmuser = await bot.fetch_user(user id as int)
await dmuser.send("This is a test!")

on_message：

@bot.event
async def on_message(message):
    dmuser = await bot.fetch_user(message.author.id)
    await dmuser.send("This is a test!")

命令示例1：

@client.command()
async def test(ctx):
    dmuser = await bot.fetch_user(ctx.author.id)
    await dmuser.send("This is a test!")

命令示例二：

@client.command()
async def test(ctx, user:discord.Member):
    dmuser = await bot.fetch_user(user.id)
    await dmuser.send("This is a test!")

discord.py v1.0.0+

从v1.0.0开始，不再使用client.send_message发送消息，而是使用abc.Messageable的send()，它实现了以下内容：

• discord.TextChannel
• discord.DMChannel
• discord.GroupChannel
• discord.User
• discord.Member
• commands.Context

示例

使用bot.command()（推荐）：

from discord.ext import commands

bot = commands.Bot(command_prefix="!")

@bot.command()
async def suggest(ctx, *, text: str):
    me = bot.get_user(YOUR_ID)
    await me.send(text)  # or whatever you want to send here

带on_message：

from discord.ext import commands

bot = commands.Bot()

@bot.event
async def on_message(message: discord.Message):

    if message.content.startswith("!suggest"):
        text = message.content.replace("!suggest", "")
        me = bot.get_user(YOUR_ID)
        await me.send(text)  # or whatever you want to send here
