javascript - 使用 discord.js 和 ytdl-core 播放音频文件

Question

我正在尝试使用 ytdl 和 discord.js 下载并播放从 youtube 获取的音频文件:

        ytdl(url)
            .pipe(fs.createWriteStream('./music/downloads/music.mp3'));

        var voiceChannel = message.member.voiceChannel;
        voiceChannel.join().then(connection => {
            console.log("joined channel");
            const dispatcher = connection.playFile('./music/downloads/music.mp3');
            dispatcher.on("end", end => {
                console.log("left channel");
                voiceChannel.leave();
            });
        }).catch(err => console.log(err));
        isReady = true

我成功地播放了 ./music/downloads/中没有 ytdl 部分的 mp3 文件 (ytdl(url).pipe(fs.createWriteStream('./music/downloads/music.mp3')) ;)。但是当那部分在代码中时，机器人只是加入和离开。

这是带有 ytdl 部分的输出:

Bot has started, with 107 users, in 43 channels of 3 guilds.
joined channel
left channel

这是没有 ytdl 部分的输出:

Bot has started, with 107 users, in 43 channels of 3 guilds.
joined channel
[plays mp3 file]
left channel

为什么会这样，我该如何解决？

使用playStream当您需要播放音频流时，而不是 playFile。

const streamOptions = { seek: 0, volume: 1 };
var voiceChannel = message.member.voiceChannel;
        voiceChannel.join().then(connection => {
            console.log("joined channel");
            const stream = ytdl('https://www.youtube.com/watch?v=gOMhN-hfMtY', { filter : 'audioonly' });
            const dispatcher = connection.playStream(stream, streamOptions);
            dispatcher.on("end", end => {
                console.log("left channel");
                voiceChannel.leave();
            });
        }).catch(err => console.log(err));
