如何在discord.js中根据用户id查找用户

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('!findUser')) {
    const userId = message.content.split(' ')[1]; // 获取用户ID
    const user = client.users.cache.find(u => u.id === userId); // 根据用户ID查找用户

    if (user) {
      message.channel.send(`找到用户：${user.tag}`);
    } else {
      message.channel.send('未找到该用户');
    }
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');
