Я успешно подключился к чату с использованием IRC-стартера javascript-программа .
При запуске программы я могу видеть сообщения на канал, к которому я подключаюсь, но всякий раз, когда я посылаю сигнал NAMES через socket.send('NAMES'), twitch возвращает мне код 421 unknown command.
Что я действительно хотел бы знать, как я могу получить список пользователей, присутствующих в настоящее время на канале?
Ниже приведена моя слегка измененная версия предоставленного чата:
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);
};

that value in local storage. It will show up when you click Populate Leaderboard in the UI.

var parsed = this.parseMessage(message.data);
if(parsed !== null){
console.log(parsed)

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);
}
}
}
};

var socket = this.webSocket;
console.log($(".message-text").val())

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')
}
}

var socket = this.webSocket;

console.log('Initializing connection and authenticating...');
console.log('username: ' + this.username);
console.log('password: ' + this.password);

socket.send('CAP REQ :twitch.tv/membership');
}
};

console.log('Disconnected from the chat server.');
};
chatClient.prototype.close = function close(){
if(this.webSocket){
this.webSocket.close();
}
};
