discord.js检查guild是否有一个具有特定名称的通道，如果有，将该通道id存储到一个变量中

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

client.once('ready', () => {
    console.log(`Logged in as ${client.user.tag}!`);
    const guild = client.guilds.cache.get('YOUR_GUILD_ID'); // 替换为你的服务器ID
    const channelName = '特定通道名称'; // 替换为你想要查找的通道名称
    let channelId = null;

    guild.channels.cache.forEach(channel => {
        if (channel.name === channelName) {
            channelId = channel.id;
        }
    });

    if (channelId) {
        console.log(`找到通道ID: ${channelId}`);
    } else {
        console.log('未找到指定名称的通道');
    }
});

client.login('YOUR_BOT_TOKEN'); // 替换为你的机器人token
