我想与telnet控制台建立多重连接。该项目适用于Teamspeak和Teamspeak，只需与telnet通信即可。我是一个使用net lib创建telnet连接作为套接字的对象。如果我们只有一个实例连接所有工作正常，我通过telnet连接返回服务器列表。但如果我有两个例子他说invalid loginname or password。登录信息是正确的，他也尝试只连接到一台服务器。

如果我调用示例，则一切正常，但示例二具有描述错误。
示例1：
test1 = new TeamspeakQueryClient({
"alias": "First-Coder Testinsance",
"ip": "first-coder.de",
"port": 10011,
"client": "serveradmin",
"password": "SECURE"
});
示例2：
test1 = new TeamspeakQueryClient({
"alias": "First Insance",
"ip": "HIDDEN",
"port": HIDDEN,
"client": "serveradmin",
"password": "SECURE"
});
test2 = new TeamspeakQueryClient({
"alias": "Second Instance",
"ip": "HIDDEN",
"port": HIDDEN,
"client": "serveradmin",
"password": "SECURE"
});
答案 0 :(得分：0)
根据您的错误，您的第二个实例未发送正确的登录信息：
错误ID = 520 msg =无效\ sloginname \ sor \ spassword
显示的其他错误是由于您的代码无法正确处理错误。 例如：
socket.on("connect", function() {
...
if(err === null) {
if(err.id === 3329) {
如果err === null，为什么err会有一个元素id？
这很可能是代码错误，实际上你的意思是err !== null
$this.SendCommand("serverlist", null, function(err, response, rawResponse){
console.log(response);
if(response[0] === undefined) {
此错误会触发，因为未捕获（上面）上一个错误。
此时，客户端未登录（已授权）。
因此，当发送serverlist命令时，它会装配另一个错误。
此附加错误也无法处理，而是立即使用response。
