1. 環境：windows server 2012 （64bit）
2. 下載： 從 https://nodejs.org/download/ 下載 Windows Installer (.msi)
3. 安裝：下一步。。。。
4. 測試：
4.1 寫範例
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 http://127.0.0.1:1337/‘);
4.2 執行
node example.js
4.3 進入。。。
通過瀏覽器訪問http://127.0.0.1:1337得到Hello World的響應
玩耍 socket.io
1. follow 它： http://socket.io/get-started/chat/
2. 所遇問題
2.1 安裝express 時遇到 proxy 問題
npm ERR! node v0.12.4npm ERR! npm v2.10.1npm ERR! code ECONNREFUSEDnpm ERR! errno ECONNREFUSEDnpm ERR! syscall connectnpm ERR! Error: connect ECONNREFUSEDnpm 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 thenpm ERR! ‘proxy‘ config is set properly. See: ‘npm help config‘
2.1.1 找proxy
http://superuser.com/questions/346372/how-do-i-know-what-proxy-server-im-using
2.1.2 設定proxy
call [npm help config] 就知道啦。。。
2.2 問題二：
PS E:\test> node index.jslistening on *:3000express deprecated res.sendfile: Use res.sendFile instead index.js:6:7
2.2.1 改sendfile為sendFile
遇到問題：
TypeError: path must be absolute or specify root to res.sendFile
follow 它： http://stackoverflow.com/questions/25463423/res-sendfile-absolute-path
我改：
app.get(‘/‘, function(req, res){ res.sendFile(path.join(__dirname,‘index.html‘));});
還有問題
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‘));});
最終版本
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‘);});
