@bot.command()
async def userinfo(ctx):
    member = ctx.message.author
    roles = member.roles[::-1]  # 颠倒角色列表顺序
    roles_str = ', '.join([role.name for role in roles])  # 将角色列表转换为字符串

    embed = discord.Embed(title="User Info", color=discord.Color.blue())
    embed.add_field(name="Username", value=member.name, inline=False)
    embed.add_field(name="ID", value=member.id, inline=False)

    await ctx.send(embed=embed)

bot.run("YOUR_BOT_TOKEN")
