使用 Discord 机器人接收用户的音频

Question

我正在开发一个不和谐项目，在该项目中我需要录制用户声音，我正在关注此文档。到目前为止，这就是我写的：const fs = require('fs');const Discord = require('discord.js');const client = new Discord.Client();client.once('ready', () => {    console.log('Ready!');});client.on('message', async message => {    if (message.content === 'a' && message.member.voice.channel) {        const connection = await message.member.voice.channel.join();        const audio = connection.receiver.createStream('user_id?', { mode: 'pcm' });        audio.pipe(fs.createWriteStream('user_audio'));    }});client.login('token');但问题是 user_audio 文件总是空的！

Answer 1

这是discord.js 中的一个错误，为了解决这个问题，我们需要播放音频......

const fs = require('fs');

const Discord = require('discord.js');

const client = new Discord.Client();

const { Readable } = require('stream');

const SILENCE_FRAME = Buffer.from([0xF8, 0xFF, 0xFE]);

class Silence extends Readable {

  _read() {

    this.push(SILENCE_FRAME);

    this.destroy();

  }

}

client.once('ready', () => {

    console.log('Ready!');

});

client.on('message', async message => {

    if (message.content === 's' && message.member.voice.channel) {

        const connection = await message.member.voice.channel.join();

        const audio = connection.receiver.createStream(message, { mode: 'pcm', end: 'manual' });

        audio.pipe(fs.createWriteStream('user_audio'));

        connection.play(new Silence(), { type: 'opus' });

        console.log(message.member.user.id);

    }

});

client.login('token');
