求助 MongoDB 服务起来了，但是 Node 连结 MongoDB 始终错误。
求助 MongoDB 服务起来了，终端可以使用 shell 可以查询，但是 Node 始终连结不上？ Node代码如下
const mongoose = require('mongoose');
const db = mongoose.connect('mongodb://localhost:27017/test');
db.Promise = global.Promise;
db.connection.on('error', function(error) {
console.log('___db：error');
console.log(error);
});
db.connection.on('open', function() {
console.log('___db:open');
});
打印的错误堆栈信息
___db：error

浏览器访问：http://localhost:27017 显示：It looks like you are trying to access MongoDB over HTTP on the native driver port. 哪里出问题了？

说出来大家可能不信
const db = mongoose.connect('mongodb://localhost:27017/test');
改成
const db = mongoose.connect('mongodb://127.0.0.1:27017/test');
这样就不会报错了，我的天啊
