【问题描述】：

我正在尝试创建一个机器人，它会在拒绝规则后发送给 DM 用户。

@client.event
async def on_reaction_add(reaction, user):
    regulamin_channel = client.get_channel(864135527963820032)
    if reaction.emoji == "????":
        Role = discord.utils.get(user.guild.roles, name="Member")
        Role2 = discord.utils.get(user.guild.roles, name="Apply")
        await user.add_roles(Role)
        await user.remove_roles(Role2)
    if reaction.emoji == "????":
        await user.send("You must accept the rules")

不幸的是，我收到了这个错误：

【问题讨论】：

你应该解释DM，因为这是一个discord特定的缩写。请记住：请始终发布完整的错误消息（包括文件和行号）。这将有助于定位问题。期待你的edit??????️

【参考方案1】：

方法 .send() 不在作为用户传递给功能的 ClientUser 上，在文档中这是 ClientUser https://discordpy.readthedocs.io/en/stable/api.html#clientuser

但是你需要获取一个 User 对象来传递给函数或者在某个地方获取它https://discordpy.readthedocs.io/en/stable/api.html#discord.User

非常感谢！
