Question

因此，我试图通过Visual Studio Code中的discord.js-commando编写Discord机器人。我正在尝试对音乐播放器进行编码，并且能够使该机器人加入语音通道。但是，在输入要播放的URL时，终端给我这个错误：

(node:17316) DeprecationWarning: Collection#filterArray: use 
Collection#filter instead

这是代码：

const commando = require('discord.js-commando');
const YTDL = require('ytdl-core');

function Play(connection, message)
{
    var server = server[message.guild.id]
    server.dispatcher = connection.playStream(YTDL(server.queue[0], {filter: "audioonly"}));
    server.queue.shift();
    server.dispatcher.on("end", function(){
        if(server.queue[0])
        {
            Play(connection, message);
        }
        else
        {
            connection.disconnect();
        }
    });
}

class JoinChannelCommand extends commando.Command
{
    constructor(client)
    {
        super(client,{
            name: 'play',
            group: 'music',
            memberName: 'play',
            description: 'Plays whatever you link from YouTube.'
        });
    }

    async run(message, args)
    {
        if(message.member.voiceChannel)
        {
            if(!message.guild.voiceConnection)
            {
                if(!servers[message.guild.id])
                {
                    servers[message.guild.id] = {queue: []}
                }
                message.member.voiceChannel.join()
                    .then(connection =>{
                        var server = servers[message.guild.id];
                        message.reply("Successfully joined!")
                        server.queue.push(args);
                        Play(connection, message);
                    })
            }
            else
            {
                message.reply("You must first join a voice channel before inputting the command.")
            }
        }
    }
}

module.exports = JoinChannelCommand;

对此我有点陌生，所以谢谢您的帮助。

该问题发生在var server = server[message.guild.id]，表示它无法读取524399562249601026的属性undefined。因此，在这种情况下server是未定义的。

查看更多代码片段，我认为您输入的是错字，应该是servers[...]而不是server[...]。
