NodeJS + Socket.io連接事件處理程序未被成功調用？

我在一個名爲server.js和index.html的文件中有以下代碼NodeJS + Socket.io連接事件處理程序未被成功調用？

由於某些原因，io.on（'connection'）部分在其回調函數中未調用console.log方法在我的網絡瀏覽器中導航到我的服務器。

查看下面的代碼，它自己說話。 server.js

var express = require('express'), 
    app = express(), 
    io = require('socket.io')(app.Server), 
    mongoose = require('mongoose'), 
    bodyParser = require('body-parser'), 
    apiRouter = require('./app/routes/api.js'); 

//Clears Node Console. 
process.stdout.write('\033c'); 
console.log('Server starting!'); 

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

app.use('*', function(req, res, next) { 
    //All requests return single page angular application. 
    res.sendFile(__dirname + '/public/index.html'); 
}); 

mongoose.connect('localhost', 'triviaattack', function(err) { 
    if (err) { 
     console.log('An error occured when connecting to the MongoDB Database'); 
     throw err; 
    } 
}); 

io.on('connection', function(socket) { 
    console.log('client connected via socket'); //This is the line that isn't being called 
}); 

app.listen(1337, function() { 
    console.log('Server started successfully @ ' + Date()); 
});

的index.html

<!DOCTYPE html> 

<html ng-app="myApp"> 
<head> 
    <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.4/angular.min.js"></script> 
    <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.4/angular-route.min.js"></script> 
    <script src="./app/app.js"></script> 

    <script src="https://cdn.socket.io/socket.io-1.3.5.js"></script> 
    <script> 
     var socket = io(); 
    </script> 

</head> 
<body> 
    <div ng-controller="HomeCtrl"> 
     {{message}} 
    </div> 
</body> 
</html>

找到了答案。

必須將server.js更改爲以下內容，請注意頂部附近的新http變量。仍然有點好奇，爲什麼只是在app.Server傳遞不工作在我的原始帖子...哦，好。

var app = require('express')(), 
    http = require('http').Server(app), 
    io = require('socket.io')(http), 
    mongoose = require('mongoose'), 
    bodyParser = require('body-parser'), 
    apiRouter = require('./app/routes/api.js'); 

//Clears Node Console. 
process.stdout.write('\033c'); 
console.log('Server starting!'); 

app.use(bodyParser.urlencoded({ extended: false })); 
app.use(apiRouter); 

app.use('*', function(req, res, next) { 
    //All requests return single page angular application. 
    res.sendFile(__dirname + '/public/index.html'); 
}); 

mongoose.connect('localhost', 'triviaattack', function(err) { 
    if (err) { 
     console.log('An error occured when connecting to the MongoDB Database'); 
     throw err; 
    } 
}); 

io.on('connection', function(socket) { 
    console.log('client connected via socket'); 
}); 

http.listen(1337, function() { 
    console.log('Server started successfully @ ' + Date()); 
});
