【问题描述】：

我正在尝试让这个不和谐机器人工作。这个想法很简单，让机器人在有人加入语音聊天时发送通知。 我在 Atom 上做这个，我得到的错误是这个：

TypeError: Cannot read property 'send' of undefined
at Client.client.on (C:\Users\Franco\Desktop\bot\bot.js:15:20)
at emitTwo (events.js:126:13)
at Client.emit (events.js:214:7)
at VoiceStateUpdateHandler.handle (C:\Users\Franco\Desktop\bot\node_modules\discord.js\src\client\websocket\packets\handlers\VoiceStateUpdate.js:39:16)
at WebSocketPacketManager.handle (C:\Users\Franco\Desktop\bot\node_modules\discord.js\src\client\websocket\packets\WebSocketPacketManager.js:103:65)
at WebSocketConnection.onPacket (C:\Users\Franco\Desktop\bot\node_modules\discord.js\src\client\websocket\WebSocketConnection.js:333:35)
at WebSocketConnection.onMessage (C:\Users\Franco\Desktop\bot\node_modules\discord.js\src\client\websocket\WebSocketConnection.js:296:17)

at emitOne (events.js:116:13)
at WebSocket.emit (events.js:211:7)

代码尝试：

client.on("message", function(message) 
  client.on('voiceStateUpdate', (oldMember, newMember) => 
    console.log('lol');
    let newUserChannel = newMember.voiceChannel
    let oldUserChannel = oldMember.voiceChannel
    var channel = client.channels.get('353996293154144259');
    if(oldUserChannel === 353996293154144260 && newUserChannel !== 489674797261783041) 
      channel.send('has joined a voice channel');
      // User Joins a voice channel
     else if(newUserChannel === 489674797261783041)
       channel.send('has left a voice channel');
    // User leaves a voice channel
    
  )
)

console.log 仅用于测试voiceStateUpdate 是否正常工作。

当我尝试运行它时，我得到了这个错误：

“TypeError: 无法读取未定义的属性‘发送’”

据我了解，错误是因为 .send 函数未定义

我几乎从这里得到了所有东西：

https://www.reddit.com/r/discordapp/comments/6p85uf/discordjs_any_way_to_detect_when_someone_enter_a/ https://discord.js.org/#/docs/main/stable/general/welcome

我尝试过的一切：

添加client.on("message", function(message)

将.send 编辑为.message 和.sendMessage

尝试定义.send

将 client.channels.get 更改为 lient.channelid.get

更改/删除var channel = client.channels.get('353996293154144259');

将client.on('voiceStateUpdate', (oldMember, newMember) => 移出client.on("message", function(message) 当我这样做时，我又遇到了另一个错误

“当我将 client.on 移出时出现第二个错误：”（节点：18196）MaxListenersExceededWarning：检测到可能的 EventEmitter 内存泄漏。添加了 11 个消息侦听器。使用emitter.setMaxListeners() 增加限制"

也许是一些无用的信息：

353996293154144259 = Discord 服务器上一般聊天的 ID

353996293154144260 = 第一次语音聊天的 id

489674797261783041 = 第二次语音聊天的 id

更新

好的，我解决了部分问题，我需要使用 message.channel.send('has joined a voice channel'); 而不是 channel.send('has joined a voice channel'); 但我无法让它按我的意愿工作。

特别感谢 YakovL。他帮助我使这篇文章更完整、更好。

【问题讨论】：

据我所知，client.channels.get('353996293154144259');返回身份不明。

如果我尝试不使用该行，我仍然会收到相同的错误，即使我更换它

频道中可能没有 353996293154144259

是的，它现在，353996293154144259 它是我的不和谐测试服务器的一般聊天 ID

给我一个味道，添加一行client.channels.forEach((i,j)=>console.log(j))，看看是否真的有你提供的id的对象。

【参考方案1】：

我是巴西人，我的语言是巴西葡萄牙语！

const Discord = require('discord.js'),
  client = new Discord.Client(),
  colors = require('colors/safe');

client.on('voiceStateUpdate', (oldMember, newMember) => 
  
  let newUserChannel = newMember.channelID;
  let oldUserChannel = oldMember.channelID;
  let userid = newMember.id;

// ----------- verificação --------------

  let selfmute = newMember.mute;
  let mute = newMember.selfMute;
  let selfmute1 = oldMember.mute;
  let mute1 = oldMember.selfMute;
  let selfdeaf = newMember.selfDeaf;
  let selfdeaf1 = oldMember.selfDeaf;  
  let selfvid = newMember.selfVideo;
  let selfvid1 = oldMember.selfVideo;
  let deaf = newMember.deaf;
  let deaf1 = oldMember.deaf;
  let servmute = newMember.serverMute;
  let servmute1 = oldMember.serverMute;

  if ( selfmute == true ) return;
  if ( mute == true ) return;
  if ( selfmute1 == true ) return;
  if ( mute1 == true ) return;
  if ( selfdeaf == true ) return;
  if ( selfdeaf1 == true ) return;
  if ( selfvid == true ) return;
  if ( selfvid1 == true ) return;
  if ( deaf == true ) return;
  if ( deaf1 == true ) return;
  if ( servmute == true ) return;
  if ( servmute1 == true ) return;

// -------- definindo cores ----------

var a = colors.red('[-] ');
var b = colors.green('[+] ');
var c = colors.blue('[!] ');

// -------- menssagem / log ----------

       if ( newUserChannel === "827668874542579797")  //id voice channel

          console.log(c+"- id: "+userid)
          console.log(b+"- Entrou em: "+newUserChannel);   

        else if ( oldUserChannel === "827668874542579797")  //id voice channel
           
           console.log(c+"- id: "+userid)
           console.log(a+"- Saiu de: "+oldUserChannel);

        else 

           console.log(c+"- Ratos estão dialogando...");

       
    
)
//----------------Comando pra ficar on-------------

client.login("TOKEN");

【参考方案2】：

替换

var channel = client.channelID.get('353996293154144259');

与

var channel = client.channels.get('353996293154144259');

编辑： 从 v12 开始，它是

var channel = client.channels.cache.get('353996293154144259');

【讨论】：

对我来说，这是行不通的，如果我把 var channel = client.channels.get('353996293154144259');或 var channel = client.channelID.get('353996293154144259');我无法让机器人将正确的消息发送到 353996293154144259 感谢您的帮助

【参考方案3】：

var channel = client.channels.get('353996293154144259');

这对我不起作用，所以我改用它：

const channel = client.channels.cache.filter((channel) => channel.name === 'name').first();

最好使用这个但搜索ID：

const channel = client.channels.cache.filter((channel) => channel.id === '353996293154144259').first();
