节点 js 404 未找到'localhost:3000/register/'

Question

嗨，我是nodejs和express的新手，我正在努力用这个框架记录路由。我创建了一个路由，但当我用它的URL运行项目时，我出现了典型的错误，404没有找到。

routes/register.js:

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

//REGISTRO
router.get('/register', function(req, res, next){
res.render('register')
});
module.exports = router;

app.js

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var registerRouter = require('./routes/register');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use('/register', registerRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;

我不习惯这个框架。我通常使用laravel或django，但路由和使用视图似乎非常不同。

您已经在/register/register下注册了路由，这意味着当您到达寄存器路由时，加载寄存器路由，然后它就没有/路径，只有另一个/register。因此，它将把这两条路径连接到/register/register。

从使用方法中删除url

app.use(registerRouter);

或更改路线。注册到

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

//REGISTRO
router.get('/', function(req, res, next){
res.render('register')
});
module.exports = router;
