angularJS + mongoose：TypeError：无法读取未定义的属性“模型”

-1

我有一个简单的快速应用程序，它应该提供发布某些内容的端点。当调用$ HTTP在我的控制，我得到了以下错误：angularJS + mongoose：TypeError：无法读取未定义的属性“模型”

TypeError: Cannot read property 'model' of undefined at new model (C:\Webpages\veryNiceWords\API\node_modules\mongoose\lib\model.js:738:17) at C:\Webpages\veryNiceWords\API\api.js:24:17 at Layer.handle [as handle_request] (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\layer.js:95:5) at next (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\route.js:131:13) at Route.dispatch (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\route.js:112:3) at Layer.handle [as handle_request] (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\layer.js:95:5) at C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:277:22 at Function.process_params (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:330:12) at next (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:271:10) at C:\Webpages\veryNiceWords\API\api.js:16:2 at Layer.handle [as handle_request] (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\layer.js:95:5) at trim_prefix (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:312:13) at C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:280:7 at Function.process_params (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:330:12) at next (C:\Webpages\veryNiceWords\API\node_modules\express\lib\router\index.js:271:10) at C:\Webpages\veryNiceWords\API\node_modules\body-parser\lib\read.js:129:5

我不知道这意味着什么，或者如何解决它。有人可以看看我的代码并指出我做错了什么吗？

api.js（明示应用）

var express = require('express'); 
var bodyParser = require('body-parser'); 
var mongoose = require('mongoose'); 
var Words = require('./models/words.js'); 
//initialize our express app 
var app = express(); 
//use body parser with JSON 
app.use(bodyParser.json()); 

//middleware for CORS requests 
app.use(function(req, res, next) { 
    res.header('Access-Control-Allow-Origin', '*'); 
    res.header('Access-Control-Allow-Methods', 'GET, PUT, POST, DELETE'); 
    res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization'); 

    next(); 
}); 

//register endpoint 
app.post('/API/addWords', function(req, res) { 
    //get user from request body 
    var words = req.body; 

    var newWords = new Words.model({ 
     author: words.author, 
     source: words.source, 
     quote: words.quote 
    }); 

    newWords.save(function(err) { 
     if (err) throw err; 

    console.log('words saved!'); 
    }); 
}); 

//connect to mongoDB 
mongoose.connect(''); 

//define our server 
var server = app.listen(3000, function() { 
    console.log('api listening on ', server.address().port); 
});

words.js（由API所需的模型）

// grab the things we need 
var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 

// create a schema 
var wordsSchema = new Schema({ 
    author: String, 
    source: String, 
    quote: String 
}); 

var Words = mongoose.model('Words', wordsSchema); 

// make this available to our users in our Node applications 
module.exports = Words;

前端HTML：

<div class="container-fluid"> 
    <div class="row"> 
     <div class="form-group"> 
      <form ng-submit="submit()"> 
       <label for="author">Author:</label> 
       <input type="text" class="form-control" id="author" ng-model="author" placeholder="Maya Angelou"> 
       <br> 
       <label for="source">Source:</label> 
       <input type="text" class="form-control" id="source" ng-model="source" placeholder="I know why the caged bird sings"> 
       <br> 
       <label for="quote">Quote:</label> 
       <textarea class="form-control" rows="10" id="quote" ng-model="quote" placeholder="There is no greater agony than bearing an untold story inside you"></textarea> 
       <br> 
       <div class="col-xs-4 col-xs-offset-4"> 
        <input class="btn btn-default postQuote" type="submit" value="Quote it"></div> 
      </form> 
     </div> 
    </div> 
</div> 

<div class="container"> 
    <p>{{ author }}</p> 
    <p>{{ source }}</p> 
    <p>{{ quote }}</p> 
</div>

前 - 控制器：

'use strict'; 

angular.module('frontEndApp') 
    .controller('AddwordsCtrl', function($scope, $http) { 
     $scope.submit = function() { 

      var url = 'http://localhost:3000/API/addWords'; 
      var words = { 
       author: $scope.author, 
       source: $scope.source, 
       quote: $scope.quote 
      }; 

      $http.post(url, words) 
       .success(function(res) { 
        console.log('posted quote!'); 
       }) 
       .error(function(err) { 
        console.log(err); 
       }); 
     }; 
    });

感谢您的帮助。

有一个在var newWords = new Words.model({问题，它应该是var newWords = new Words({

new Words.model(不是必需的。只需要new Words(。

请更正代码。
