Chat Bot twitch IRC 集成，无法从 NAMES 421 Unknown Command 获得响应

Question

我已使用 IRC 启动器成功连接到 twitch 聊天 javascript program。

当运行程序时，我能够看到发送到我连接的频道的消息，但每当我通过 socket.send('NAMES') 发送 NAMES 信号时，抽搐 returns我一个 421 unknown command 代码。

我真正想知道的是，如何获得频道中当前存在的用户列表？

我对所提供的聊天机器人稍作修改的版本如下：

var chatClient = function chatClient(options){
    this.username = options.username;
    this.password = options.password;
    this.channel = options.channel;

    this.server = 'irc-ws.chat.twitch.tv';
    this.port = 443;
}

chatClient.prototype.open = function open(){
    this.webSocket = new WebSocket('wss://' + this.server + ':' + this.port + '/', 'irc');

    this.webSocket.onmessage = this.onMessage.bind(this);
    this.webSocket.onerror = this.onError.bind(this);
    this.webSocket.onclose = this.onClose.bind(this);
    this.webSocket.onopen = this.onOpen.bind(this);
};

chatClient.prototype.onError = function onError(message){
    console.log('Error: ' + message);
};

/* This is an example of a leaderboard scoring system. When someone sends a message to chat, we store 
   that value in local storage. It will show up when you click Populate Leaderboard in the UI. 
*/
chatClient.prototype.onMessage = function onMessage(message){
    if(message !== null){
        var parsed = this.parseMessage(message.data);
        if(parsed !== null){
            console.log(parsed)
            if(parsed.command === "PRIVMSG") {
                userPoints = localStorage.getItem(parsed.username);

                if(userPoints === null){
                    localStorage.setItem(parsed.username, 10);
                }
                else {
                    localStorage.setItem(parsed.username, parseFloat(userPoints) + 0.25);
                }
            } else if(parsed.command === "PING") {
                this.webSocket.send("PONG :" + parsed.message);
            }
        }
    }
};

chatClient.prototype.message = function message(){
    var socket = this.webSocket;

    console.log($(".message-text").val())

    if (socket !== null && socket.readyState === 1) {
        console.log("socket not null")
        socket.send("PRIVMSG " + this.channel + " :" + $(".message-text").val() + "\r\n")
        console.log("PRIVMSG " + this.channel + " :" + $(".message-text").val())
    }
}

chatClient.prototype.names = function names(){
    var socket = this.webSocket;

    if (socket !== null && socket.readyState === 1) {
        socket.send('NAMES')
    }
}    

chatClient.prototype.onOpen = function onOpen(){
    var socket = this.webSocket;

    if (socket !== null && socket.readyState === 1) {
        console.log('Initializing connection and authenticating...');
        console.log('username: ' + this.username);
        console.log('password: ' + this.password);
        console.log('channel: ' + this.channel);

        socket.send('PASS ' + this.password);
        socket.send('NICK ' + this.username);
        socket.send('JOIN ' + this.channel);
        socket.send('CAP REQ :twitch.tv/tags');
        socket.send('CAP REQ :twitch.tv/commands');
        socket.send('CAP REQ :twitch.tv/membership');
    }
};

chatClient.prototype.onClose = function onClose(){
    console.log('Disconnected from the chat server.');
};

chatClient.prototype.close = function close(){
    if(this.webSocket){
        this.webSocket.close();
    }
};

显然 Twitch IRCd 不支持请求 NAMES 命令。但支持加入频道时回复NAMES

你几乎做对了所有事情。

为了获得频道名单并真正加入，您应该先提交您的 CAP 请求，然后加入频道。当服务器响应时，他也会给你频道名称列表。

实际订单

socket.send('CAP REQ :twitch.tv/tags');
socket.send('CAP REQ :twitch.tv/commands');
socket.send('CAP REQ :twitch.tv/membership');
socket.send('JOIN ' + this.channel);
