discord.js如何按名称查找角色

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

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

client.on('message', message => {
  if (message.content.startsWith('!findRole')) {
    const roleName = message.content.slice(10); // 获取消息中的角色名称
    const guild = message.guild; // 获取当前服务器的Guild对象

    const role = guild.roles.cache.find(r => r.name === roleName); // 使用find方法按名称查找角色

    if (role) {
      message.channel.send(`找到了角色：${role.name}`);
    } else {
      message.channel.send(`未找到角色：${roleName}`);
    }
  }
});

client.login('your-token-goes-here');
