'app.router'已被弃用!在简单的网站上

我非常喜欢将NodeJS与Express结合使用。我正在尝试使用Bootstrap组件创建一个简单的网站。我使用Express生成器生成了以下文件夹结构

  • app.js
  • bin(文件夹)
  • node_modules(文件夹)
  • package.json
  • public(文件夹:css,javascript,img)
  • routes(index.js,oudRijswijk.js)
  • views(玉器文件)

Express(版本4.13.1) NodeJS(版本0.10.25)

一切正常,直到我在app.js文件中添加一些额外的路线。

APP.JS

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var nodemailer = require('nodemailer');

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

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(app.router);
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

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

routes.initialize(app);

app.use('/OudRijswijk', oudRijswijk);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err
    });
  });
}

// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {}
  });
});


module.exports = app;

在文件夹中使用命令“npm start”启动NodeJS服务器后,我收到以下错误:

Error: 'app.router' is deprecated!

我希望你能帮我解决这个问题。

非常感谢

根据迁移指南,已删除手动执行app.use(app.router)的需要。 现在你可以直接使用(例如):

app.get('/'...); app.post(...);

之后不添加'app.use(app.router)'行。
