使用mongoskin操作MongoDB

安装模块
cnpm install mongodb
cnpm install mongoskin

导入mongoskin  连接MongoDB中test数据库

var mongo = require(‘mongoskin‘);
var db = mongo.db("mongodb://localhost:27017/test", {native_parser: true});

操作与MongoDB原生语法大同小异  只不过多了回调

增

router.post(‘/doadd‘, function (req, res, next) {
    var param = req.body;
    if(param.username && param.password){
        //插入数据
        db.collection(‘user‘).insert({‘username‘: param.username,‘password‘:param.password}, function (err, result) {
            db.close();
            if(!err){
                res.send({‘status‘:1});
            }else{
                res.send({‘status‘:0});
            }
        });
    }
});

删

router.post(‘/dodel‘, function (req, res, next) {
    var param = req.body;
    if(param.id){
        var ObjectId = mongo.ObjectID;
        db.collection(‘user‘).remove({‘_id‘:ObjectId(param.id)}, function (err, result) {
            db.close();
            if(!err){
                res.send({‘status‘:1});
            }else{
                res.send({‘status‘:0});
            }
        });
    }
});

改

router.post(‘/doedit‘, function (req, res, next) {
    var param = req.body;
    if(param.username && param.password){
        var ObjectId = mongo.ObjectID;
        //修改单条数据
        db.collection(‘article‘).update({‘_id‘:ObjectId(param._id),‘username‘:param.username},{$set:{‘password‘: param.password}}, function (err, result) {
            db.close();
            if(!err){
                res.send({‘status‘:1});
            }else{
                res.send({‘status‘:0});
            }
        });
    }
});

查

router.get(‘/‘, function (req, res, next) {
    db.collection(‘article‘).find().toArray(function (err, result) {
        db.close();
        res.render(‘admin/index‘, {title: ‘后台管理‘,result:result});
    });
});
