Question

我正在使用MEAN堆栈编写聊天应用程序，但是在实现它们时我遇到了困难。服务器没有从客户端获得任何类型的更新，也没有向客户端发送任何内容。我猜服务器中有一些错误，但无法解决任何问题。

server.js文件是： -

 (function (exports, require, module, __filename, __dirname) { 
  var express = require('express'),
  neo4j = require('node-neo4j'),
  bodyParser = require('body-parser'),

  app = express();

 //socket io integration
 var io = require('socket.io')(3000);
 var clients = [];
 app.get('/', function (req, res) {
 res.sendfile('./index.html');
});

io.on('connection', function (socket)
{
 console.log("Server : Connected to Socket IO");
 console.info('New client connected (id=' + socket.id + ').');

 socket.on('user enter',function(user_name){
  clients.push({id:socket.id,userName:user_name});
  len=clients.length;
  io.emit('user entrance',clients,clients[len-1].id);
});

socket.on('send msg',function(data){
   socket.broadcast.to(data.id).emit('get msg',{msg:data.msg,id:data.id,name:data.name});
  });

   socket.on('disconnect', function(data){
      console.log("user disconnected :" +data.id);
  })
});

app.use(require("express").static('data'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));

 app.set('port', process.env.PORT || 5000);

 app.listen(app.get('port'), function () {
 applogger.info('Express server listening on port ' + app.get('port'));
 });

});

客户端代码（chatController.js）是 -

angular.module('myApp')
  .controller('ChatCtrl',function($rootScope, $scope, $stateParams,socket,$ionicScrollDelegate,$timeout) {

$scope.userName = $scope.user.name;

socket.on('connect',function()
{
  console.log("from userListCtrl : "+ JSON.stringify($rootScope.selectedUser));
  $scope.selected_id=$rootScope.selectedUser;

});

socket.emit('user enter',$scope.userName);

  socket.on('user entrance',function(data,my_id){
  //checking the user id
  if($scope.my_id==null){
    $scope.my_id=my_id;
  }
  $scope.user_show=data;

});

$scope.send_msg = function($event){
var keyCode = $event.which || $event.keyCode;
if($scope.selected_id==$scope.my_id){
  alert("You can't send msg to your self.");
}else{
  if (keyCode === 13) {
    var data={
      id:$scope.selected_id,
      msg:$scope.msg_text,
      name:$scope.userName
    };
    $scope.msg_text='';
      socket.emit('send msg',data);
    }
  }
};



//Getting the messages from server.
socket.on('get msg',function(data){
  $scope.msgs=data;
  $scope.is_msg_show=true;
  addMessage();
});

// function of push messages to an array.

UI部分非常干净，它是您可以单击的用户列表，它将打开一个聊天窗口，这两个用户可以亲自聊天。除了将msg发送到服务器并从中获取响应之外，每个事情都发生在客户端（例如用户详细信息，消息内容等）。我陷入了困境。

套接字IO服务器既不向客户端发送也不从客户端接收任何消息：带有离子的MEAN
