// Módulos
const express = require('express');

const bodyparser = require('body-parser');
const app = express() 
const admin = require('./routes/admin.js');
// const mongoose = require('mongoose');
// Config
// Body Parser
app.use(bodyparser.urlencoded({extended:true}));
app.use(bodyparser.json);
//Handlebars
app.engine('handlebars', handlebars({defaltLayout: 'main'}));
app.set('view engine','handlebars');
//Mongoose
//Rotas  
app.use('/admin',admin);
//Outros
const PORT = 8081;
app.listen(PORT, () => {
console.log('Servidor Rodando');

const router = express.Router();
router.get('/', (req,res) => {
res.send('Pagina principal, painel de adm')
})

res.send('Pagina de posts');
})
router.get('/categorias',(req,res) => {
res.send('Pagina de categorias');

Answer 1

我设法解决了错误，遵循代码APP.JS

// Módulos
const express = require('express');
const handlebars = require('express-handlebars');
const bodyparser = require('body-parser');
const app = express();
const admin = require("./routes/admin.js");
// const mongoose = require('mongoose');
// Config
// Body Parser
app.use(bodyparser.urlencoded({extended:true}));
app.use(bodyparser.json());
//Handlebars
app.engine('handlebars', handlebars({defaultLayout: 'main'}));
app.set('view engine','handlebars');
//Mongoose
//Rotas  
app.use('/admin', admin);
//Outros
const PORT = 8081;
app.listen(PORT, () => {
console.log('Servidor Rodando');
})

ADMIN.JS

const express= require('express');
const router = express.Router();
router.get('/', (req,res) => {
res.send("Pagina principal do painel ADM");
})
router.get('/posts', (req,res) => {
res.send("Pagina de posts");
})
router.get('/categorias', (req,res) => {
res.send("Pagina de categorias");
})

module.exports = router;

Answer 2

如果你试图访问根URL，即http://localhost:8081/，那么你必须编写处理该路由的代码，目前你的代码只处理http://localhost:8081/admin/*路由，所以如果这是一个错误，那么为根创建一个路由。

App.js文件中的-

APP.JS

// Módulos
const express = require('express');
const handlebars = require('express-handlebars');
const bodyparser = require('body-parser');
const app = express() 
const admin = require('./routes/admin.js');
// const mongoose = require('mongoose');
// Config
// Body Parser
app.use(bodyparser.urlencoded({extended:true}));
app.use(bodyparser.json());
//Handlebars
app.engine('handlebars', handlebars({defaltLayout: 'main'}));
app.set('view engine','handlebars');
//Mongoose

//Rotas
//here is the code to handle the root route

app.get('/',(req, res)=>{
res.send("this is the homepage");
});  
app.use('/admin',admin);
//Outros
const PORT = 8081;
app.listen(PORT, () => {
console.log('Servidor Rodando');
})
