添加路由规则

听着李健的《传奇》，敲着dell的键盘，用着windows10的系统，我写下了这篇博客，关于express路由规则的添加。

app.js：

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 routes = require('./routes/index');
//var users = require('./routes/users');

var app = express();

// view engine setup
app.set('port',process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
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')));


routes(app);

app.listen(app.get('port'), function(){
    console.log('Express server listening on port ' + app.get('port'));
});

index.js：

module.exports = function(app){
    app.get('/',function(req,res){
        res.render('index',{title: 'Express'});
    });

    app.get('/nswbmw',function (req,res){
        res.send('hello.world!')
    });
};

记得改写命令后，ctrl+c，退出，重启，运行命令： node app.js

localhost:3000/nswbmw
