Question

我是NodeJs的新手。现在我正在尝试socket.io。我想建立像Zopim（https://www.zopim.com/）这样的网站。现在我正在努力：客户端（A）应该只从一个管理员获取帮助热线，并防止其他管理员与客户端（A）聊天。这是server.js

  var app = require('express')();
  var bodyParser = require('body-parser');
  var mysql = require("mysql");
  var http = require('http').Server(app);
  var io = require('socket.io')(http);
  app.use(require("express").static('data'));
  app.use(bodyParser.urlencoded({
   extended: true
  }));
  app.use(bodyParser.json());
  /* Creating MySQL connection.*/
  var con  = mysql.createPool({
   host     : 'localhost',
   user     : 'root',
   password : '',
   database :'Chat_tryout'
   });
  var insertRecord = 'Insert into mytable(socketid,receiver,message)value(?,?,?)';
  app.get("/",function(req,res){
  res.sendFile(__dirname + '/index.html');
});
var msg={};
io.on('connection', function(socket){
console.log(socket.id + "connected");

socket.on('message',function(msg){
console.log('user' +this.id+ 'sent message"'+ msg +'"');
    //console.log(" admin id " + io.sockets.connected[socketid]);

con.getConnection(function(err, connection) {
var message=msg;
var socketid=" ";
con.query( insertRecord,[socketid,socket.id,msg], function(err, res) {  
if(err){
    console.log("error:" + err);
}else
    console.log ("inserted"+ socket.id +"message"+ msg);
    //res.end(``);
});
});
app.post('/get_data', function (req, res) {
var msg=req.body.name;
var toid = req.body.toid;
//var socketid = this.socket.sessionid;
//console.log(socketid);
console.log(toid);

io.to(toid).emit('mymessage',msg);
con.getConnection(function(err,connection){
var message=msg;
con.query( insertRecord,[socketid,toid,msg], function(err, res) {   
if(err){
    console.log("error:" + err);
}else
    console.log ( "inserted "+ socket.id +" message "+ msg);
});
});
});
}); 
socket.on('disconnect', function() {
console.log('client socketio disconnect!');
});

app.get('/api/getalldata', function(req,res){
con.getConnection(function(err,connection){
con.query( 'select * from mytable', function(err, rows) {   
if(err){
    console.log("error:" + err);
}else
    console.log ("success");
    res.json(rows);
});   
    }); 
});

});
http.listen(8080,function(){
console.log("Listening on http://127.0.0.1:8080/");
});

 var socket = io.connect("http://localhost:8080");
 socket.on('message', function(msg){
    $('#messages').append($('<li>').text(msg));
  });

我正在使用html前端为客户端发送和接收消息：

 var socket = io.connect("http://localhost:8080");
  $('form').submit(function(){
  socket.emit('message', $('#message').val());
  $('#message').val('');
  return false;
  });
  socket.on('mymessage', function(msg){
    $('#messages').append($('<li>').text(msg));
  });

socket.io nodeJs angularjs一对一聊天
