Discord.js v13 @discordjs/voice 播放命令进频道但无法播放音乐求助

以下是代码存在的问题和对应修复方法：

• 缺失核心依赖引入
  代码中调用了ytdl获取音频流但未引入对应依赖，首先安装ytdl-core包，再在代码顶部添加引入语句：

  const ytdl = require('ytdl-core');
  

• 搜索结果判断逻辑错误
  当前的判断条件会导致搜索结果仅1条时直接返回空值，修改videoFinder内的返回逻辑：

  return (videoResult.videos.length > 0) ? videoResult.videos[0] : null;
  

• 音频播放器配置错误
  导入的NoSubscriberBehavior未使用，默认配置下无订阅者时播放器会自动暂停，修改播放器创建逻辑：

  const player = createAudioPlayer({
    behaviors: {
      noSubscriber: NoSubscriberBehavior.Play
    }
  });
  

• 方法调用顺序与异步误用
  player.play()不是异步方法，无需加await，且需要先完成订阅再触发播放，调整逻辑为：

  connection.subscribe(player);
  player.play(resource);
  

• 缺少语音相关网关意图
  Discord.js v13需要手动开启网关意图，确认创建客户端时已添加GUILD_VOICE_STATES意图：

  const client = new Discord.Client({
    intents: [
      Discord.Intents.FLAGS.GUILDS,
      Discord.Intents.FLAGS.GUILD_MESSAGES,
      Discord.Intents.FLAGS.GUILD_VOICE_STATES
    ]
  });
  

• 音频流配置优化
  给ytdl添加缓存参数，避免音频加载中断：

  const stream = ytdl(video.url, { 
    filter: 'audioonly',
    highWaterMark: 1 << 25
  });
  

• 缺少FFmpeg转码依赖
  @discordjs/voice依赖FFmpeg完成音频转码，需要在运行环境中安装FFmpeg并配置环境变量，也可以直接安装ffmpeg-static包引入使用。

修正后完整代码 #

const ytdl = require('ytdl-core');
const Discord = require('discord.js')

    NoSubscriberBehavior

    async run(client, message, args) {

        const voiceChannel = message.member.voice.channel;

        const videoFinder = async (query) => {
            const videoResult = await ytsearch(query);
            return (videoResult.videos.length > 0) ? videoResult.videos[0] : null;
        }
        const video = await videoFinder(args.join(' '));
        if (video) {
            const stream = ytdl(video.url, { filter: 'audioonly', highWaterMark: 1 << 25 });
            const player = createAudioPlayer({
                behaviors: {
                    noSubscriber: NoSubscriberBehavior.Play
                }
            });
            const resource = createAudioResource(stream)

            connection.subscribe(player);
            player.play(resource);

            await message.reply(`:thumbsup: Now Playing *${video.title}*`)
            
        } else {
            message.channel.send('No video results found');
        }
    }
}
