javascript - Nodejs Rest API : UnhandledPromiseRejectionWarning: TypeError: News. 查找不是函数

Question

当我点击新闻 api 时，我似乎一直收到错误

UnhandledPromiseRejectionWarning: TypeError: News.find 不是函数

我阅读了有关 Promises 的内容，但无法解决这个问题。这是 Mongoose 的东西吗？我该如何解决？

我的 Controller NewsController.js

const NewsController = {};
const News = require('../models/news.model');

// await indicates wait for the function to get over.
// we may also use Promises in its place
NewsController.getNews = async function(req, res) {
    const allnews = await News.find({}, function(err, ns) {
            assert.equal(err, null);
            res.json(ns);
        });
      //res.json(allnews);

  };
  // ES6 style
  NewsController.getSingleNews = async (req, res) => {

      const news = await News.findById(req.params.Id);
      res.json[news];
    };
    NewsController.createNews = async (req, res) => {
        const news = new News(req.body);
        await news.save();

        res.json[{
          'status': 'item saved successfully'
        }];
      };

      NewsController.deleteNews = async (req, res) => {
        await News.findByIdAndRemove(req.params.id);
        res.json[{
          'status': 'item deleted successfully'
        }]
      };

module.exports = NewsController;

我的模型 news.model.js

const mongoose = require('mongoose');


const {Schema}= mongoose;
const newsSchema = new Schema({
  title: {type: String, required:true},
  content:{type: String, required:true},
  author:{type: String},
  image:{type: String},
  source:{type: String}
});

mongoose.exports = mongoose.model('news', newsSchema);

问题是 mongoose.exports。应该是 module.exports 谢谢@AnthonyWinzlet
