Question

我收到此错误消息：

这些是我app.js文件的内容

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 mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/emedb');

var Schema = mongoose.Schema;

// create a schema
var userSchema = new Schema({
name: { type: String, required: true,},
email: { type: String, required: true,},
password: { type: String, required: true },
location: String,
age: Number,
created_at: Date,
updated_at: Date
});

// on every save, add the date
userSchema.pre('save', function(next) {
// get the current date
var currentDate = new Date();

// change the updated_at field to current date
this.updated_at = currentDate;

// if created_at doesn't exist, add to that field
if (!this.created_at)
this.created_at = currentDate;

next();
});

var User = mongoose.model('emedb', userSchema);

// post to db
app.post('/newBen', function(req,res){
new user({
    name: req.body.name,
    email: req.body.email, 
    password: req.body.password,
    location: req.body.location,
    age: req.body.age,
    created_at: req.currentDate,
    updated_at: req.currentDate
}).save(function(err, doc){
    if(err)res.json(err);
    else res.send('Thank you for joining');
});res.end();
});

module.exports = User;

另外还有另外70行我觉得这里发帖有点太多了。还有我的表格，这是一个非常标准的玉文件。如果需要，我会发布它。它有一个名称和一个类，方法是post，动作是/ new。

这是我在mongodb的第一次尝试，我觉得我非常接近它。或者我在几英里之外？我尝试找到教程，大部分代码来自一个，但我怀疑它可能有几年了。

请添加此行。

您尚未创建服务器实例

var express = require('express');

var app = express();

从nodejs app中的表单插入monogdb
