Question

我目前正在尝试学习MEAN堆栈。本教程是关于任务管理器的。现在，我正在尝试连接到mongodb地图集以检索数据库中的示例数据，但是它们没有显示http://localhost:3000/api/tasks

这是我的task.js文件

var express = require('express');
var router = express.Router();
var mongojs = require('mongojs');
var db = mongojs('drivers',['tasks']);


router.get('/tasks', function(req, res, next){
    db.tasks.find(function(err, tasks){
        if(err){
            res.send(err);
        }
        res.json(tasks);
    });
});

module.exports = router;

这是我的server.js文件

var express = require('express');
var path = require('path');
var bodyParser = require('body-parser');
var index = require('./routes/index');
var task = require('./routes/tasks');
var app = express();
var port = 3000;

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.engine('html', require('ejs').renderFile);

app.use(express.static(path.join(__dirname, 'client')));

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

app.use('/', index);
app.use('/api', task);

app.listen(port, function(){
    console.log('Server started on port' +port);
});

这是我的package.json文件

{
  "name": "mytasklist",
  "version": "1.0.0",
  "description": "Task Manager",
  "main": "server.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

    "mongojs": "^2.6.0"
  }
}

问题解决了，我为我的nodejs驱动程序粘贴了错误的版本。

无法连接群集mongo.db地图集
