获取歌曲队列 discord.js 的视频缩略图

Question

因此，每当播放新歌时，我都会尝试获取视频缩略图，因此当播放新歌并显示“正在播放：${song.title}”它还会在标题旁边发送视频的缩略图，但我不知道该怎么做？

} else {
    serverQueue.songs.push(song)
    if(playlist) return undefined
    song.videoURL = 'the url for the thumbnail';
    return message.channel.send(`__**${song.title}**__ has been queued`)
}
return undefined
}

function play(guild, song) {
    const serverQueue = queue.get(guild.id)

    if(!song) {
        serverQueue.voiceChannel.leave()
        queue.delete(guild.id)
        return
    }

    const dispatcher = serverQueue.connection.play(ytdl(song.url))
    .on('finish', () => {
      serverQueue.songs.shift()
      play(guild, serverQueue.songs[0])
    })
    .on('error', error => {
        console.log(error)
    })
    dispatcher.setVolumeLogarithmic(serverQueue.volume / 5)

    let embed = new Discord.MessageEmbed()
    .setTitle(`Now Playing: __**${song.title}**__`)
    .setColor('#FF0000')
    serverQueue.textChannel.send(embed)
}

Answer 1

您可以尝试使用song.thumbnail。如果您使用 ytdl，它将起作用：

} else {
    serverQueue.songs.push(song)
    if(playlist) return undefined
    song.videoURL = 'the url for the thumbnail';
    return message.channel.send(`__**${song.title}**__ has been queued`)
}
return undefined
}

function play(guild, song) {
    const serverQueue = queue.get(guild.id)

    if(!song) {
        serverQueue.voiceChannel.leave()
        queue.delete(guild.id)
        return
    }

    const dispatcher = serverQueue.connection.play(ytdl(song.url))
    .on('finish', () => {
      serverQueue.songs.shift()
      play(guild, serverQueue.songs[0])
    })
    .on('error', error => {
        console.log(error)
    })
    dispatcher.setVolumeLogarithmic(serverQueue.volume / 5)

    let embed = new Discord.MessageEmbed()
    .setTitle(`Now Playing: __**${song.title}**__`)
    .setImage(song.thumbnail)
    .setColor('#FF0000')
    serverQueue.textChannel.send(embed)
}
