如何在discord.js中创建反应角色？

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('messageReactionAdd', async (reaction, user) => {
  // 在这里处理添加反应的逻辑
});

client.on('messageReactionRemove', async (reaction, user) => {
  // 在这里处理移除反应的逻辑
});

client.on('messageReactionAdd', async (reaction, user) => {
  if (reaction.message.partial) await reaction.message.fetch();
  if (reaction.partial) await reaction.fetch();
  
  if (user.bot) return; // 忽略机器人的反应
  
  if (reaction.message.id === '消息ID') { // 替换为你想要添加反应角色的消息ID
    if (reaction.emoji.name === '🔴') { // 替换为你想要的反应emoji
      let role = reaction.message.guild.roles.cache.find(role => role.name === "角色名称"); // 替换为你想要分配的角色名称
      let member = reaction.message.guild.members.cache.get(user.id);
      member.roles.add(role).catch(console.error);
    }
  }
});

client.on('messageReactionRemove', async (reaction, user) => {
  if (reaction.message.partial) await reaction.message.fetch();
  if (reaction.partial) await reaction.fetch();
  
  if (user.bot) return; // 忽略机器人的反应
  
  if (reaction.message.id === '消息ID') { // 替换为你想要移除反应角色的消息ID
    if (reaction.emoji.name === '🔴') { // 替换为你想要的反应emoji
      let role = reaction.message.guild.roles.cache.find(role => role.name === "角色名称"); // 替换为你想要移除的角色名称
      let member = reaction.message.guild.members.cache.get(user.id);
      member.roles.remove(role).catch(console.error);
    }
  }
});

client.login('你的Discord bot令牌');
