我试图在我的快速应用程序中添加一个新路由,但是当尝试启动服务器时,我会收到错误.错误是
C:\development\node\express_app\node_modules\express\lib\router\index.js:252
throw new Error(msg);
^
Error: .get() requires callback functions but got a [object Undefined]
这是我的文件,我是新的节点,所以让我知道,如果我省略了一个重要的文件
路线/ furniture.js
exports.furniture = function(req,res){
res.render('furniture',{ title: '4\267pli' });
};
路线/ index.js
/*
* GET home page.
*/
exports.index = function(req,res){
res.render('index',{ title: '4\267pli' });
};
意见/ furniture.ejs
<!DOCTYPE html>
<html>
<head>
<title>4·pli -- architecture</title>

app.js
/**

var express = require('express'),routes = require('./routes'),user = require('./routes/user'),furniture = require('./routes/furniture'),http = require('http'),path = require('path');
var app = express();
// all environments
app.set('port',process.env.PORT || 3000);
app.set('views',__dirname + '/views');
app.set('view engine','ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodoverride());
app.use(app.router);
app.use(require('stylus').middleware(__dirname + '/public'));
app.use(express.static(path.join(__dirname,'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/',routes.index);
app.get('/users',user.list);
app.get('/furniture',routes.furniture);
http.createServer(app).listen(app.get('port'),function(){
console.log('Express server listening on port ' + app.get('port'));
});
解决方法
麻烦是：
routes = require('./routes'),
这3个都设置你的路由文件夹,而不是一个特定的文件,express将会找到一个index.js(找不到,然后是>错误)
exports.xxxx = function(req,res){
res.render('xx',{ foo: foo);
};
然后,您的项目文件夹结构应如下所示：
routes/
├── index.js
│
├── user/
│ └── index.js (with a exports.user inside)
│
└── fourniture/
└── index.js (with a exports.furniture inside)
app.js
// a folder called routes with the index.js file inside
routes = require('./routes')
.
.
.
app.get('/',routes.main_function);
app.get('/sec_route',routes.sec_function);
app.post('/other_route',routes.other_function);
/routes/index.js
exports.main_function = function(req,res){
res.render('template1',{ foo: foo });
};
exports.sec_function = function(req,res){
res.render('template2',{ bar: bar });
};
exports.other_function = function(req,{ baz: baz });
};
