Discord机器人使用@bot.command注册指令后无响应故障求助

• 重复实例化客户端：commands.Bot 是 discord.Client 的子类，本身就支持所有原生Client的事件监听功能。你当前代码同时创建了client、bot两个完全独立的客户端实例，事件回调都注册在client上，命令都注册在bot上，最后运行的是client.run()，bot实例根本没有启动，自然不会响应任何命令。
• 缺少消息内容权限：Discord API v10 及以上版本强制要求机器人显式开启message_content意图才能读取服务器内的普通消息内容，未开启该权限时机器人无法识别消息中的指令前缀和命令，自然无法触发命令回调。同时你初始化bot实例时没有传入已经配置好的intents参数。

import discord
from discord.ext import commands
from dotenv import load_dotenv
import os
import json
import random
import requests

# 配置权限
intents = discord.Intents.default()
intents.members = True
intents.message_content = True # 必须开启消息内容意图

# 直接用Bot实例，不需要额外创建Client
bot = commands.Bot(command_prefix="<:givebanana:852295575772856400>", intents=intents)

@bot.event
async def on_ready():
    print('We have logged in as {0.user}'.format(bot))
    global points
    try:
        with open('data.txt') as f:
            points = json.load(f)
    except FileNotFoundError:
        print("Could not load data.txt")
        points = {}

@bot.event
async def on_member_join(member):
    embed=discord.Embed(title="Welcome",description="Be sure to change your status. Once that is done, you will be assigned the monke intern role. Why don't you say hello to our new monke, <@&852658353678319656>. Viva la monke!", color=discord.Color.from_rgb(0,128,0))
    embed.set_thumbnail(url=member.avatar_url)
    channel = bot.get_channel(852677413367709706)
    await channel.send(f"{member.mention}", embed=embed)

@bot.command()
async def roles(ctx):
    embed=discord.Embed(title="Monke Roles",description="The more people DM you 'monke', the more points you earn.", color=discord.Color.from_rgb(255,255,53))
    embed.set_thumbnail(url="http://www.clker.com/cliparts/f/1/e/9/H/i/banana-md.png")
    embed.add_field(name="Points",value="Someone DMs you and joins the server= 2 points\n\nSomeone DMs you but doesn't join= 1 point\n",inline=False)
    embed.add_field(name="🐵 Monke Employee",value="1 Point", inline=True)
    embed.add_field(name="🪖 Monke Soldier",value="5 Points",inline=True)
    embed.add_field(name="🚨 Monke Officer",value="10 Points",inline=True)
    embed.add_field(name="🎖️ Monke General",value="20 Points",inline=True)
    embed.add_field(name="🎩 Monke Mayor",value="30 Points",inline=True)
    embed.add_field(name="🏙️ Monke Govenor",value="50 Points",inline=True)
    embed.add_field(name="🏛️ Monke President",value="100 Points",inline=True)
    await ctx.send(ctx.author.mention,embed=embed)
    print('Command Sucessful')

@bot.command()
async def ping(ctx):
    await ctx.send('_**AH AH**_  Here!')

# 运行bot实例，不是client
bot.run('censoredtoken')

注意：修改代码后需要先进入Discord开发者平台的对应机器人管理页，在「Privileged Gateway Intents」区域开启Message Content Intent开关，否则权限不足依然无法读取消息内容。
