var mongoose = require(\'mongoose\');
mongoose.connect(\'mongodb://127.0.0.1:27017/whhhh\', { useMongoClient: true });
var db = mongoose.connection;
db.on(\'error\', console.error.bind(console, \'connection error:\'));
db.once(\'open\', function (callback) {
    console.log("数据库成功连接");
});
module.exports = db;

try.js

var User = require("./user.js");

/**

 */
function insert() {

    var user = new User({
        username : \'zhangxiao\',                 
        usersex: \'nan\',                            
        userage: 17,                                //年龄
                             
    });

    user.save(function (err, res) {

        if (err) {
            console.log("Error:" + err);
        }
        else {
            console.log("Res:" + res);
        }

    });

var mongoose = require(\'mongoose\');
var db = require("./db.js");
  var   Schema=mongoose.Schema;

var UserSchema = new mongoose.Schema({

    usersex:{type:String},
    userage:{type:Number}
