var express = require(‘express‘);

//引入mongodb模块
var MongoClient = require(‘mongodb‘).MongoClient;
var DB_STR = "mongodb://localhost:27017/blog";//这里的是在mongodb下建立的库
var ObjectId = require(‘mongodb‘).ObjectId;  //这里主要是用来处理mongodb下id的

/* GET users listing. */

        }
        //此处的db，就是blog数据库
        var c = db.collection(‘category‘);
