Question

我有问题通过node.js和express.js路由视图我的项目树看起来像：

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

我使用快递和路径;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')));

我收到了这个错误：

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)

当我尝试从公共目录中获取文件时，我收到此错误：

Cannot GET /js/login.js

实际上我知道本地路径和服务器路径有所不同，我已经阅读了堆栈溢出中已经提到的很多相关问题，但我找不到我的错误。

更新

路由代码在这里：

var router = express.Router（）; 要求（ './路由器'）（应用程序）;

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);
};

在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;

您使用的是哪种快递版本？

在Express 4中间件是在外部模块中构建的，所以对于你的静态文件，你应该使用serve-static中间件：

示例代码：

public class MovieSession implements Comparable<MovieSession> {

    private String movieName;
    private char rating;
    private Time sessionTime;
    private SeatReservation[][] sessionSeats;
    public static int NUM_ROWS;
    public static int NUM_COLS;

    public MovieSession(String movieName, char rating, Time sessionTime) {
        this.movieName = movieName;
        this.rating = rating;
        this.sessionTime = sessionTime;
    }
This is the method where it gives me the error:

    @Override
    public int compareTo(MovieSession currentMovieSession) {

        if (this.sessionTime < currentMovieSession.sessionTime)
        {
            return -1;
        }
         else if (this.sessionTime > currentMovieSession.sessionTime) 
         {
            return 1;
         }
        if(this.sessionTime == currentMovieSession.sessionTime)
        {
            return this.movieName > currentMovieSession.movieName ? 1 : -1;
        }
    }

Answer 2

因为我是使用node.js进行编码并上传到服务器上的初学者，所以我正在通过 npm 在服务器上运行我的代码，通过帮助我的朋友，我发现我必须运行 pm2 来获取实时应用。

Answer 3

我也遇到了这个错误，但在精神上有些疲劳后，我能够解决这个问题。这是对我来说很好用的解决方案。将这行代码 app.set('views', path.join(__dirname, 'views')); 更改为 app.set('views', path.join(__dirname, '../views')); this。

无法通过express.js和path在views目录中查找视图
