Node.js TypeError：熊不是一个函数

我想学习本教程中的node.js： https ： //scotch.io/tutorials/build-a-restful-api-using-node-and-express-4

当我到创build一个熊POST / api /熊部分，我从邮递员得到以下错误

它说熊是不是一个函数，当我实例化它的变种熊=新熊（）; 是当我得到错误。

这是我的bear.js

// app/models/bear.js var mongoose = require('mongoose'); var Schema = mongoose.Schema; var BearSchema = new Schema({ name: String }); module.exports = mongoose.model('Bear', BearSchema); 

这里是我的server.js

 // server.js // BASE SETUP // ============================================================================= // call the packages we need var express = require('express'); // call express var app = express(); // define our app using express var bodyParser = require('body-parser'); var mongoose = require('mongoose'); mongoose.connect('mongodb://node:[e-mail]:27017/Iganiq8o'); // connect to our database var Bear = require('./app/models/bear'); // configure app to use bodyParser() // this will let us get the data from a POST app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); var port = process.env.PORT || 8080; // set our port // ROUTES FOR OUR API // ============================================================================= var router = express.Router(); // get an instance of the express Router // middleware to use for all requests router.use(function(req, res, next) { // do logging console.log('Something is happening.'); next(); // make sure we go to the next routes and don't stop here }); // test route to make sure everything is working (accessed at GET http://localhost:8080/api) router.get('/', function(req, res) { res.json({ message: 'hooray! welcome to our api!' }); }); // <-- route middleware and first route are here // more routes for our API will happen here // on routes that end in /bears // ---------------------------------------------------- router.route('/bears') // create a bear (accessed at POST http://localhost:8080/api/bears) .post(function(req, res) { var bear = new Bear(); // create a new instance of the Bear model bear.name = req.body.name; // set the bears name (comes from the request) // save the bear and check for errors bear.save(function(err) { if (err) res.send(err); res.json({ message: 'Bear created!' }); }); }); // REGISTER OUR ROUTES ------------------------------- // all of our routes will be prefixed with /api app.use('/api', router); // START THE SERVER // ============================================================================= app.listen(port); console.log('Magic happens on port ' + port); 

我能做些什么来做一个function？ 提前致谢。

对不起，我不能评论。

试试这个东西：

1.使用本地mongodb数据库，在这里设置连接string给你：

  mongoose.connect('mongodb://node:[e-mail]:27017/Iganiq8o'); 

2.在邮差中设置身体参数，而不是头。
