Question

我正在尝试使用node .js构建一个聊天系统，这是一个非常基本的项目，但是我无法使其正常工作。我有一个app.js文件（基本上是我的服务器文件），一个用于管理index.html请求的client.js文件和一个应由消息传递系统负责的chatroomManager.js文件。

app.js文件

    <things>
      <code V="123"/>
      <region V="38"/>
      <hl_list>
        <hl>
          <stuff_hmv V="XXX" DN="some other stuff"/>
          <secondary_code V="Z98"/>
          <infotext V="max 12 units"/>
          <kl_list>
            <kl V="I" DN="some other stuff">
              <diag_list>
                <diag V="WS1" DN="illness 1"/>
                <diag V="WS2" DN="illness 2"/>
                <diag V="EX1" DN="illness 3"/>

              </diag_list>
            </kl>
          </kl_list>
        </hl>
      </hl_list>
    </things>
    <things>
      <code V="456"/>
      <region V="45"/>
      <hl_list>
        <hl>
          <stuff_hmv V="X1X" DN="some other stuff"/>
          <infotext V="max 13 units"/>
          <kl_list>
            <kl V="II" DN="some other stuff">
              <diag_list>
                <diag V="WS1" DN="illness 3"/>
                <diag V="WS2" DN="illness 2"/>
                <diag V="EX1" DN="illness 4"/>

              </diag_list>
            </kl>
          </kl_list>
        </hl>
      </hl_list>
    </things>

client.js文件

    const User = require('./public/scripts/User');
const express = require("express");
const app = express();
var server = require('http').createServer(app);
var io=require('socket.io')(server);
var bodyParser = require('body-parser')
var fs = require("fs");


var userlist= new Array();

app.use(express.static('public'));
app.use(bodyParser.urlencoded({ extended: false }))


app.get('/', function (req, res) {
    res.sendFile(__dirname + '/public/views/index.html');
});

app.get('/:roomname',function (req,res) {
    res.sendFile(__dirname + '/public/views/chatroom.html', {name:req.params.roomname});
});


io.on('connection', function(socket){

    //Leggiamo le rooms attuali
    var contents = fs.readFileSync("public/scripts/rooms.json");
    let rooms = JSON.parse(contents);
    socket.emit('parse',rooms);

    //un utente prova a connettersi
    socket.on('connection tried', function (name,room) {
        if(!find(name)){                                        //see if username is available
            const user = new User(name, room," ");
            userlist.push(user);                                //insert user in userlist
            socket.join(room);                                  //user joins the room
            socket.broadcast.to(room).emit('room-entrance',room,user); //telling the room that user is in
            socket.emit('redirect', room, user);                //user joins the room
        }
        else
            socket.emit('RegistrationErr','username');          //in case username isn't available error is logged

    });

    socket.on('user log',function (user,room) {     
        console.log(user, room);
        socket.to(room).emit('welcome');
    });

});

chatroomManager.js文件

$(function () {
    var socket = io()

    socket.on('parse',function (rooms) {
        options(rooms);
    });

    $('#formElem').submit(function (e) {
        e.preventDefault();
        let roomSel=document.getElementById('room');
        socket.emit('connection tried', $('#name').val(), roomSel.options[roomSel.selectedIndex].value);
        return false;
    });

    socket.on('RegistrationErr', function (error) {  /* IMPLEMENT THIS*/
        console.log(error)
    });
    socket.on('redirect',function (room, user) {

         //questo evento viene emesso per il chatroom manager che sa che un utente è entrato
        window.location.href='/'+room;
    })





});

基本上，最后，“欢迎”应该在控制台上记录，但是什么都没有记录。我该如何解决？
