Question

我设法在heroku上部署了应用程序，这是链接：https://damp-reef-60581.herokuapp.com

当您导航到此链接时：https://damp-reef-60581.herokuapp.com/ 通常显示整个页面，

但是当您导航到https://damp-reef-60581.herokuapp.com/movies时您会看到错误：Cannot GET /movies

在本地主机中：我导航至以下路由：

http://localhost:8000/movies/movies
http://localhost:8000/movies/review
http://localhost:8000/movies/theatre

我需要在我的server.js中进行什么更改才能使其在heroku中正常运行？

here is my server: 
const express = require('express');
const path = require('path');
const flash = require('connect-flash');
const bodyParser = require('body-parser');
const cors = require('cors');
const mongoose = require('mongoose');
const db = require('./app/config/database');

// Connect To Database
mongoose.connect(db.database);

// On Connection
mongoose.connection.on('connected', () => {
  console.log('Connected to database '+db.database);
});

// On Error
mongoose.connection.on('error', (err) => {
  console.log('Database error: '+err);
});

const app = express();

const movies = require('./app/routes/movies');

// Port Number
const port = process.env.PORT || 8000

// CORS Middleware
app.use(cors());

// Set Static Folder
app.use(express.static(path.join(__dirname, '/movies-client/dist/movies-client')));
// Body Parser Middleware
app.use(bodyParser.json());

app.use('/movies', movies);

app.get('/', (req, res) => {
  res.sendFile(path.join(__dirname + '/movies-client/dist/movies-client/index.html'));
});

// Start Server
app.listen(port, () => {
  console.log('Server started on port '+port);
});

我想我明白您的问题所在。在您的app.js中，您拥有以下内容：

app.use('/movies', movies);

然后在您的./app/routes/movies中打赌您有类似的东西

router.get('/movies', function(req, res, next){ ....

或类似的东西。问题是两个/movies都加了。您要告诉服务器“在路径/movies上使用路由器movies。但是在movies路由器内部，您还有另一个/movies。因此，如果要使用这样的路由：localhost:8000/movies应该在./app/routes/movies内定义路线，如下所示：

router.get('/', function(req, res, next){ ....

因为您已经告诉服务器您在/movies内部的app.js路径中
