NodeJS mongo-express错误:无法获取/

Question

我正在尝试使用Mongo-Express来查找我的mongoDB，在我进入user并通过后，我得到了错误-> Cannot /

    var express = require('express')
  , routes = require('./routes')
  , http = require('http');

var _ = require('underscore');
var async = require('async');
var utils = require('./utils');

var mongodb = require('mongodb');
var cons = require('consolidate');
var swig = require('swig');
var swigFilters = require('./filters');
var app = express();

var config = require('./config');

//Set up swig
app.engine('html', cons.swig);

Object.keys(swigFilters).forEach(function (name) {
    swig.setFilter(name, swigFilters[name]);
});

//App configuration
app.configure(function(){
  if(config.useBasicAuth){
    app.use(express.basicAuth(config.basicAuth.username, config.basicAuth.password));
  }
  app.set('views', __dirname + '/views');
  app.set('view engine', 'html');
  app.set('view options', {layout: false});
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(config.site.baseUrl,express.static(__dirname + '/public'));
  app.use(express.bodyParser());
  app.use(express.cookieParser(config.site.cookieSecret));
  app.use(express.session({
    secret: config.site.sessionSecret,
    key: config.site.cookieKeyName
  }));
  app.use(express.methodOverride());
  app.use(app.router);

});

Answer 1

首先，试着从实际/更新的教程中学习。实际的express版本是4，它删除了：

 app.use(app.router);

(因此我对过时教程的推断)第二件事，我在你的代码中看不到任何路由。如果你想从服务器得到响应，你需要写路由。例如：

app.get('/test', function(req, res) {
    res.send('Hello from route');
});
