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

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

client.on('messageReactionAdd', (reaction, user) => {
  // 检查添加反应的消息是否满足条件
  if (reaction.message.content === '特定消息内容' && reaction.emoji.name === '特定表情符号') {
    const guild = reaction.message.guild;
    const member = guild.members.cache.get(user.id);

    // 获取要添加的角色
    const role = guild.roles.cache.find(role => role.name === '要添加的角色名称');

    // 添加角色给用户
    member.roles.add(role)
      .then(() => console.log(`Added role ${role.name} to ${member.user.tag}`))
      .catch(console.error);
  }
