Question

我试图模块化我的应用程序分隔路线，但唯一有效的是根路线，我不知道我的代码的问题是什么，在阅读{{ 3}}，我的代码似乎写得正确

app.js

// ...
var routes = require('./routes/index');
var users = require('./routes/users');
//Require the external route
var about = require('./routes/about');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

//Routes
app.use('/', routes);
app.use('/users', users);
//The external route 
app.use('login', login);

index.js

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Clazapp' });
});

module.exports = router;

login.js

var express = require('express');
var router = express.Router();

  //login page
  router.get("/login", function(req, res, next) {
    res.render('login');
  });

module.exports = router;

如您所见，login.js和index.js的代码完全相同，但/ login路由不起作用。出现消息：

似乎找不到文件 login.jade ，但他已经位于目录/ views中。这么复杂，不管怎样？

据我所知，express.Router()必须仅用于特殊情况我使用下一种方式来模块化应用程序

// app.js
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
...
require('./routes')(app); // it's call ./routes/index.js and pass app to it

// ./routes/index.js
var smthEntity = require('./smthEntity');

module.exports = function (app) {
    app.get('/smth-path', ...smth, e.g. checkAuth, ...);
    app.get('/smthEntity', smthEntity.get);

    app.get('/login', require('./login').get);
    app.post('/login', require('./login').post));
}

// ./routes/smthEntity
var SmthEntity = require ('smthEntity'); // include models

exports.get = function(req, res, next) {
    res.render('smthEntity.html', {
        arg1: value1,
        arg2: value2
    }); 
};
... // other method and route for smthEntity

// ./routes/login
exports.get = function(req, res, next) {
    res.render('login.html', { ... });  
};

exports.post = function(req, res, next) {
    ...process post data...
};

为什么使用不同文件进行快速路由并不起作用？
