我是Nodejs和mongodb的新手，并尝试将数据插入数据库并在提交表单时获取404。不确定代码中有什么问题。任何帮助，将不胜感激。这是我的代码如下。
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 mongo = require('mongodb');
var index = require('./routes/index');
var restaurant = require('./routes/restaurant');
var shopping = require('./routes/shopping');
var hotel = require('./routes/hotel');
var aboutus = require('./routes/about');
var event = require('./routes/event');
var admin = require('./routes/admin');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
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('/', index);
app.use('/restaurant',restaurant);
app.use('/shop',shopping);
app.use('/hotel',hotel);
app.use('/about',aboutus);
app.use('/event',event);
app.use('/admin',admin);
app.use('/insert',admin);
app.use('/get-data',admin);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Page Not Found');
err.status = 404;
next(err);
});
// 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;
admin.js
var express = require('express');
var router = express.Router();
var mongo = require('mongodb');
var mongoClient = mongo.MongoClient;
var assert = require('assert');
var url = 'mongodb://localhost:27017/aligarhcity';
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('admin', { title: 'Aligarh City'});
});
//READ THE DATA FROM DATABASE
router.get('/get-data', function(req,res,next){
var resultArray = [];
mongoClient.connect(url,function (err,db) {
assert.equal(null,err);
var cursor = db.collection('shopping').find();
cursor.forEach(function(doc,err){
assert.equal(null,err);
resultArray.push(doc);
},function () {
db.close();
res.render('/admin',{item:resultArray});
});
});
});
//iNSERT THE DATA IN THE DATABASE
router.post('/insert', function(req,res,next){
var shop = {
shop_name:req.body.shop_name,
shop_address:req.body.shop_address,
shop_city:req.body.shop_city,
shop_zip:req.body.shop_zip,
shop_email:req.body.shop_email,
shop_phone:req.body.shop_phone,
shop_rating_5: '10',
shop_rating_4: '10',
shop_rating_3: '10',
shop_rating_2: '10',
shop_rating_1: '10'
};
console.log(shop_name,shop_city,shop_address,shop_zip,shop_email,shop_phone);
mongoClient.connect(url,function (err,db) {
assert.equal(null,err);
db.collection('shopping').insertOne(shop,function (err, result) {
assert.equal(null,err);
console.log('Item Inserted Successfully');
db.close();
});
});
res.redirect('/');
});
module.exports = router;

404主要来自服务器，检查您的快速实现，您尝试访问的路由是否在代码中实现
