node.js - 无法通过express.js和路径在views目录中查找 View

Question

我在通过node.js和express.js路由 View 时遇到问题我的项目树如下所示:

app/
   app.js
   views/
       index.html
       login.html
   public/
         css/
         js/

我使用express和path；这是我设置路径的代码:

app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
//forms
app.set('views', path.join(__dirname, 'views'));
//public 
app.use(express.static(path.join(__dirname, 'public')));

我收到此错误:

Error: Failed to lookup view "login.html" in views directory "/home/Project/V0.0.8_3/app/views"

    at Function.process_params (/home/Project/V0.0.8_3/node_modules/express/lib/router/index.js:335:12)

当我尝试从公共(public)目录获取文件时，出现此错误:

Cannot GET /js/login.js

实际上我知道本地路径和服务器路径之间的区别，并且我已经阅读了堆栈溢出中提出的很多相关问题，但我找不到我的错误是什么。

更新

路由代码在这里:

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

router.js:

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

module.exports = function (app) {

    /* Index(main) route */
    app.use('/', routes);
  app.use('/index', routes);
  app.use('/index.html', routes);
  app.use('/login', login);
  app.use('/login.html', login);
  app.use('/logout', logout);
};

routes目录下有两个js文件； index.js 和 login.js

index.js:

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

router.route('/')
  // fetch all users
  .get(function (req, res) {
    console.log('get method');
    if(req.session.logged) {
      res.render('index.html');
    }
    else {
      res.redirect('/login');
    }

  });    
module.exports = router;

您使用的是哪个 Express 版本？

已更新

在express 4中，中间件是内置在外部模块中的，因此对于您的情况下的静态文件，您应该使用serve-static中间件:

示例代码:

var express = require('express') 
var path = require('path') 
var serveStatic = require('serve-static')
var app = express()       
app.use(serveStatic(path.join(__dirname, 'public'))) 
app.listen(3000)
