Setup node.js on Windows Server
1. 环境：windows server 2012 （64bit）
2. 下载： 从 https://nodejs.org/download/ 下载 Windows Installer (.msi)
3. 安装：下一步。。。。
4. 测试：
4.1 写范例
var http = require(‘http‘); http.createServer(function (req, res) { res.writeHead(200, {‘Content-Type‘: ‘text/plain‘}); res.end(‘Hello World\n‘); }).listen(1337, "127.0.0.1"); console.log(‘Server running at :1337/‘);
4.2 执行
node example.js
4.3 进入。。。
通过浏览器访问:1337得到Hello World的响应
玩耍 socket.io
1. follow 它：
2. 所遇问题
2.1 安装express 时遇到 proxy 问题
npm ERR! node v0.12.4 npm ERR! npm v2.10.1 npm ERR! code ECONNREFUSED npm ERR! errno ECONNREFUSED npm ERR! syscall connect npm ERR! Error: connect ECONNREFUSED npm ERR! at exports._errnoException (util.js:746:11) npm ERR! at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1010:19) npm ERR! { [Error: connect ECONNREFUSED] npm ERR! code: ‘ECONNREFUSED‘, npm ERR! errno: ‘ECONNREFUSED‘, npm ERR! syscall: ‘connect‘, npm ERR! parent: ‘oven‘ } npm ERR! npm ERR! If you are behind a proxy, please make sure that the npm ERR! ‘proxy‘ config is set properly. See: ‘npm help config‘
2.1.1 找proxy
2.1.2 设置proxy
call [npm help config] 就知道啦。。。
2.2 问题二：
PS E:\test> node index.js listening on *:3000 express deprecated res.sendfile: Use res.sendFile instead index.js:6:7
2.2.1 改sendfile为sendFile
遇到问题：
TypeError: path must be absolute or specify root to res.sendFile
follow 它：
我改：
app.get(‘/‘, function(req, res){ res.sendFile(path.join(__dirname,‘index.html‘)); });
还有问题
ReferenceError: path is not defined"
follow 它：https://groups.google.com/forum/#!topic/express-js/4FGHcV9xGwQ
我再改：
var path = require(‘path‘); app.get(‘/‘, function(req, res){ res.sendFile(path.join(__dirname,‘index.html‘)); });
最终版本
index.js
var app = require(‘express‘)(); var http = require(‘http‘).Server(app); var io = require(‘socket.io‘)(http); var path = require(‘path‘); app.get(‘/‘, function(req, res){ res.sendFile(path.join(__dirname,‘index.html‘)); }); io.on(‘connection‘, function(socket){ console.log(‘a user connected‘); socket.on(‘disconnect‘, function(){ console.log(‘user disconnected‘); }); socket.on(‘chat message‘, function(msg){ io.emit(‘chat message‘, msg); console.log(‘message: ‘ + msg); }); }); http.listen(3000, function(){ console.log(‘listening on *:3000‘); });
