我使用生成器 Angular-Fullstack 开始了一个项目。我希望外部节点客户端（在其他机器上运行）可以连接到 Angular-FullStack 项目中的套接字服务器。

我已经用一个简单的节点服务器和客户端对其进行了测试，它工作正常。代码是：

节点服务器：

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);

var port = 9000;

server.listen(port, function(){
  console.log('Express server listening on %d port', port);
});

// __dirname is the directory where this file is placed
app.get('/', function (req, res) {
  res.sendFile(__dirname + '/browserSocketAppClient.html');
});

io.on('connection', function (socket) {
  console.log( 'THE SOCKET: ' + socket.toString());

  socket.emit('NODE SOCKET SERVER', { SERVER: 'NODE SOCKET SERVER' });

  socket.on('NODE SOCKET CLIENT', function (data) {
    console.log(data);
  });
});

节点客户端：

var io = require('socket.io-client');

var socket = io.connect('http://192.168.0.101:9000');

socket.on('connect', function() {
  console.log( 'NODE SOCKET CLIENT has connected with the server');
});

socket.on('NODE SOCKET SERVER', function (data) {
  console.log(data);
  socket.emit('NODE SOCKET CLIENT', { CLIENT: 'NODE SOCKET CLIENT' });
});

服务器控制台：

D:\003_IOT\CODE_EXAMPLES\TestSocketIO>node nodeSocketServer
Express server listening on 9000 port
{ CLIENT: 'NODE SOCKET CLIENT' }

客户端控制台

D:\003_IOT\CODE_EXAMPLES\TestSocketIO>node nodeSocketClient
NODE SOCKET CLIENT has connected with the server
{ SERVER: 'NODE SOCKET SERVER' }

但是当我想使用相同的 NODE CLIENT: Angular-Fullstack 项目时，它就不起作用了。

我已将此代码添加到 myproject/server/config/socketio.js

socketio.js

function onConnect(socket) {

  socket.emit('NODE SOCKET SERVER', { SERVER: 'You are connected with NODE SOCKET SERVER' });
  socket.on('NODE SOCKET CLIENT', function (data) {
    console.log(data);
  });
............................
}

我在服务器的控制台中得到这条递归消息，

Express server listening on NaN : 9000 in development mode

GET /socket.io/?EIO=3&transport=polling&t=1438187503827-10 200 7ms

但它从来没有真正连接过。它必须在 Angular-Fullstack 项目的服务器端的配置中，但我无法确定。

任何想法谢谢
