因为初学，跟着书本开始学习使用node-mongodb-native驱动器来操纵mongodb
但是还是因为书本使用的mongodb驱动估计太老旧，采取书本和多数网上的链接方式均报出如下错误
var server = new mongodb.Server('127.0.0.1', 27017, {});
new mongodb.Db('test', server, {}).open(function (err, client) {
if (err) throw err;
console.log('\033[96m + \033[39m connected to mongodb');
app.users = new mongodb.Collection(client, 'maning');
app.listen(3000, function () {
console.log('\033[96m + \033[39m app listening on *:3000');
});
})
报错：大概意思是集合名应该为字符串

网上很多博文都有这个错误的发生，但是没有解决的回复，本能是马上去github找原著
还真的发现我又犯傻了，人家在node-mongodb-native2.0的推荐链接方式已经和书上的完全不同
当然我没有看过变更履历，这也是小白的做法，但是长了记性，就是跟着书学编程是不靠谱的。。。凡是找API或者github原著
看过官方的方法后尝试，通过：
var MongoClient = require('mongodb').MongoClient
, assert = require('assert');
// Connection URL
var url = 'mongodb://localhost:27017/myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected correctly to server");
db.close();
});
我自己的连接测试：
var MongoClient = require('mongodb').MongoClient;
var DB_CONN_STR = 'mongodb://localhost:27017/test';
MongoClient.connect(DB_CONN_STR, function(err, db) {
console.log("连接成功！");
});
