nodejs连接mongodb的方法
一、
var express = require('express'); var mongodb = require('mongodb'); var app = express(); app.use(express.static('./website')); var url = 'mongodb://localhost:10089/test'; mongodb.MongoClient.connect(url, function (err, db) { if (err) { console.log(err); return false; } console.log(db); }); app.listen(9000); console.log('running');
二、
1、定义mongodb的连接串:
test_163:/home/exenode/part3/scms/config # more env/development.js module.exports = { port:7101, mongodb:'mongodb://localhost:10089/scms' }
2、导出此连接串的配置:
test_163:/home/exenode/part3/scms/config # more config.js var config = null; if (process && process.env && process.env.NODE_ENV){ config = require("./env/"+ process.env.NODE_ENV + ".js"); }else{ config = require("./env/development.js"); }; module.exports = config;
3、使用mongoose.connect("连接串") 方法连接mongodb
test_163:/home/exenode/part3/scms/config # more mongoose.js var mongoose = require('mongoose'); var config = require('./config'); module.exports = function(){ console.log("config:",config.mongodb); var db= mongoose.connect(config.mongodb); require('../app/models/news.server.model'); return db; }
4、在 app.js 中执行 mongoose.js 中导出的方法,连接mongodb:
test_163:/home/exenode/part3/scms # more app.js var express = require('./config/express'); var mongodb = require('./config/mongoose'); var db = mongodb(); var app = express(); module.exports = app;
