Setup node.js on Windows Server

2015-06-05 18:57 645 查看

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 http://127.0.0.1:1337/');

　　4.2 执行

node example.js

　　4.3 进入。。。

通过浏览器访问http://127.0.0.1:1337得到Hello World的响应

玩耍 socket.io

1. follow 它： http://socket.io/get-started/chat/
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
http://superuser.com/questions/346372/how-do-i-know-what-proxy-server-im-using
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： http://stackoverflow.com/questions/25463423/res-sendfile-absolute-path
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');
});
