【问题描述】：

这是我的代码， 该命令执行完美，机器人加入语音通道，还发送了即将播放的歌曲名称，但它没有播放语音通道中的歌曲。 这是我第一次在 *** 上提出问题，所以不要介意格式和内容。但我在这里真的需要帮助。 Discord v13 和最新的节点模块。

const ytsearch = require('yt-search');
const Discord = require('discord.js')
const 
    joinVoiceChannel,
    createAudioPlayer,
    createAudioResource,
    NoSubscriberBehavior
 = require('@discordjs/voice');


module.exports = 
    name: "play",
    description: "test command",

    async run(client, message, args) 

        const voiceChannel = message.member.voice.channel;
        if (!voiceChannel) return message.channel.send('Please connect to a voice channel!');
        if (!args.length) return message.channel.send('Please Provide Something To Play!')

        const connection = await joinVoiceChannel(
            channelId: message.member.voice.channel.id,
            guildId: message.guild.id,
            adapterCreator: message.guild.voiceAdapterCreator
        );
        const videoFinder = async (query) => 
            const videoResult = await ytsearch(query);
            return (videoResult.videos.length > 1) ? videoResult.videos[0] : null;


        
        const video = await videoFinder(args.join(' '));
        if (video) 
            const stream = ytdl(video.url,  filter: 'audioonly' );
            const player = createAudioPlayer();
            const resource = createAudioResource(stream)

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




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



    
``` 

【参考方案1】：

我建议您查看@discordjs/voice 上的音乐机器人example。

他们在如何从 ytdl 中提取流方面做得很好。

我目前仍在学习这一切是如何工作的，但您要查看的部分是 createAudioResource 函数。

public createAudioResource(): Promise<AudioResource<Track>> 
    return new Promise((resolve, reject) => 
        const process = ytdl(
            this.url,
            
                o: '-',
                q: '',
                f: 'bestaudio[ext=webm+acodec=opus+asr=48000]/bestaudio',
                r: '100K',
            ,
             stdio: ['ignore', 'pipe', 'ignore'] ,
        );
        if (!process.stdout) 
            reject(new Error('No stdout'));
            return;
        
        const stream = process.stdout;
        const onError = (error: Error) => 
            if (!process.killed) process.kill();
            stream.resume();
            reject(error);
        ;
        process
            .once('spawn', () => 
                demuxProbe(stream)
                    .then((probe) => resolve(createAudioResource(probe.stream,  metadata: this, inputType: probe.type )))
                    .catch(onError);
            )
            .catch(onError);
    );
