套接字.IO连接不一致

Question

我刚刚添加了socket。我的MEAN stack应用程序。它的连接不一致。下面是我启动服务器并通过浏览器连接时得到的结果:

GET /socket.io/?EIO=3&transport=polling&t=LTnYzIi 200 1.948 ms - 3956
POST /socket.io/?EIO=3&transport=polling&t=LTnYzJL 404 1.617 ms - 66
GET /socket.io/?EIO=3&transport=polling&t=LTnYzrU 200 1.612 ms - 3956
POST /socket.io/?EIO=3&transport=polling&t=LTnYzs6 404 1.974 ms - 66
GET /socket.io/?EIO=3&transport=polling&t=LTnY-jT 200 1.652 ms - 3956
POST /socket.io/?EIO=3&transport=polling&t=LTnY-kE 404 0.975 ms - 66

然而，如果我停止服务器并在浏览器发出请求(在后台)的那一刻重新启动它，客户端连接并且它工作正常。每次有通信的时候都要连接起来，对吧?请告诉我我错过了什么。

这是我的包裹。json插座。io叫:

"socket.io": "^1.4.6"

我的app.js是这样的:

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var expressValidator = require('express-validator')
var mongodb = require('mongodb');
var mongoose = require('mongoose');
mongoose.connect("mongodb://localhost/newphase1");
var async = require('async');
var config = require('./config.js');
var routes = require('./routes/index');
var api = require('./routes/api');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.use(favicon(__dirname + '/public/favicon(4).png'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, '/public')));
app.use(expressValidator({
  errorFormatter: function(param, msg, value){
    var namespace = param.split('.'),
    root = namespace.shift(),
    formParam = root;
    while(namespace.length){
      formParam += '[' + namespace.shift() + ']';
    }
    return { 
      param: formParam,
      msg:msg,
      value:value
    };
  }
}));
var api = require('./routes/api')(app,express,io);
app.use('/api', api);

app.get('*',function(req,res){
  res.sendFile(__dirname + '/public/views/index.html');
});
io.on('connection', function(socket) {
    console.log('client connected!'); 
});
http.listen(config.port,"127.0.0.1",function(err){
  if(err){
    console.log(err);
  }else{
    console.log('listening on port 3000');
  }
})

我的套接字。我的index.js(angular):

<script src="https://cdn.socket.io/socket.io-1.4.6.js"></script>

我的服务为套接字。io:

.factory('socketio',function($rootScope){
    var socket = io.connect("http://localhost:3000");
    return {
        on: function(eventName,callback){
            socket.on(eventName,function(){
                var args = arguments;
                $rootScope.$apply(function(){
                    callback.apply(socket,args);
                });
            });
        },
        emit: function(eventName,data,callback){
            socket.emit(eventName,data,function(){
                var args = arguments;
                $rootScope.apply(function(){
                    if(callback){
                        callback.apply(socket,args);
                    }
                });
            });
        }
    }
});

它确实连接，但不一致。什么好主意吗?

Answer 1

不知为什么

npm start

给了我上面的不一致，而

node app.js

没问题。
