关于mongoose连接mongodb重复访问报错的解决办法_mariadb_

 var express = require('express'); var mongoose = require('mongoose'); var router = express.Router(); var Person = mongoose.model('Person',{ id:Number, name:String }); /*新增*/ router.get('/insert', function(req, res){ var student = new Person({ id:1, name:"huop" }); mongoose.connect("mongodb://localhost:27017/test"); student.save(function(e, product, numberAffected) { if (e) res.send(e.message); var html = " 新增的数据为：" + JSON.stringify(product); html += " 影响的数据量为：" + numberAffected; res.send(html); }); }); router.get('/find',function(request, response){ mongoose.connect("mongodb://localhost:27017/test"); Person.find({ id: 1 }, function(e, docs) { if (e) response.send(e.message); var html = " 查询到的数据为：" + JSON.stringify(docs); response.send(html); }); });

 var mongoose = require(‘mongoose'); mongoose.connect(‘mongodb://localhost/nuaidibi'); module.exports = mongoose;
