Discord.py如何使下一个用户的消息成为变量？

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.messages = True
intents.guilds = True

bot = commands.Bot(command_prefix='!', intents=intents)

@bot.event
async def on_ready():
    print(f'Logged in as {bot.user}')

@bot.event
async def on_message(message):
    # 确保机器人不会对自己发送的消息做出反应
    if message.author == bot.user:
        return

    # 这里可以添加逻辑来判断是否需要获取下一个用户的消息
    # 例如，当消息内容为"!getnext"时
    if message.content == '!getnext':
        # 等待下一个用户的消息
        def check(m):
            return m.channel == message.channel and m.author != bot.user

        try:
            next_message = await bot.wait_for('message', check=check, timeout=60)
        except TimeoutError:
            await message.channel.send("No message received within 60 seconds.")
        else:
            # 将下一个用户的消息内容作为变量
            next_user_message = next_message.content
            await message.channel.send(f"Next user said: {next_user_message}")

bot.run('YOUR_BOT_TOKEN')

pip install discord.py
