【问题描述】：

如何使用 discord.js v13 从 url 播放音频。

我使用了这段代码，但它不起作用。

    const connection = joinVoiceChannel({
        channelId: channel_id.id,
        guildId: guild_id,
        adapterCreator: message.guild.voiceAdapterCreator,
    });

    const player = createAudioPlayer();
    const resource = createAudioResource('http://radioplayer.kissfmuk.com/live/')
    player.play(resource)

    connection.subscribe(player)

我已激活所有 Intent，机器人显示一个绿色圆圈，但没有播放音频。您对它的工作原理有什么想法吗？

【解决方案1】：

您尝试为其创建资源的链接必须返回一个音频文件。实时音频广播不适用于您当前的代码。如果网址给你例如.mp3 文件，代码应该可以工作。

示例函数：

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

const config =  require('./config/config.json');

const { joinVoiceChannel, createAudioPlayer, NoSubscriberBehavior, createAudioResource, AudioPlayerStatus, VoiceConnectionStatus, entersState } = require('@discordjs/voice');
const { join } = require('path');

client.once('ready', () => {
    console.log(config.onlineMessage);
    const channels = client.guilds.cache.find(f => f.name==="<Server Name>").channels;
    JoinChannel(channels.cache.find(r => r.name === "<Channel Name>"), './background.mp3', 0.025);  
});

client.login(config.token);

function JoinChannel(channel, track, volume) {
    const connection = joinVoiceChannel({
        channelId: channel.id,
        guildId: channel.guildId,
        adapterCreator: channel.guild.voiceAdapterCreator,
    });
    const player = createAudioPlayer();
    resource = createAudioResource(join(__dirname, track), { inlineVolume: true });
resource.volume.setVolume(volume);
    connection.subscribe(player); 
    connection.on(VoiceConnectionStatus.Ready, () => {console.log("ready"); player.play(resource);})
    connection.on(VoiceConnectionStatus.Disconnected, async (oldState, newState) => {
        try {
            console.log("Disconnected.")
            await Promise.race([
                entersState(connection, VoiceConnectionStatus.Signalling, 5_000),
                entersState(connection, VoiceConnectionStatus.Connecting, 5_000),
            ]);
        } catch (error) {
            connection.destroy();
        }
    });
    player.on('error', error => {
        console.error(`Error: ${error.message} with resource ${error.resource.metadata.title}`);
        player.play(getNextResource());
    });
    player.on(AudioPlayerStatus.Playing, () => {
        console.log('The audio player has started playing!');
    }); 
    player.on('idle', () => {
        connection.destroy();
    })
}

【讨论】：

链接是否可能以 .mp3 结尾？喜欢：streams.ilovemusic.de/iloveradio2.mp3
是的，这是可能的。
您会更新您的答案以包含 mp3 信息吗？很有帮助。
@Éndoxos 你能给我一个我不会工作的代码示例

【解决方案2】：

答案很简单，我只需要在播放资源之前订阅连接！

    const connection = joinVoiceChannel({
        channelId: channel_id.id,
        guildId: guild_id,
        adapterCreator: message.guild.voiceAdapterCreator,
    });


    const resource = 
    createAudioResource('https://streams.ilovemusic.de/iloveradio8.mp3', {
        inlineVolume: true
    })

    const player = createAudioPlayer();
    connection.subscribe(player)
    player.play(resource)
