使用nodejs和ejs将数据保存到mongodb

Question

app.js

const mongoose = require('mongoose');
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const methodOverride = require('method-override');
app.use(bodyParser.urlencoded({extended: true}));
app.use(methodOverride('_method'));
const request = require('request');
app.set('view engine', 'ejs');

mongoose.connect('mongodb://localhost/movies_project')
.then(() => { console.log('Connected to mongodb')})
.catch( err => console.error('Could not connect', err));

let movieSchema = new mongoose.Schema({

plot: String,
director: String,
actors: String,
ratings: Number,
votes: Number,
runtime: String,
    imdbID: String
})

const Movie = mongoose.model('Movie', movieSchema);    

app.get('/', (req, res) => {
Movie.find({}, (err, movies) => {
    if(err) console.log(err)
    else res.render('landing', {movies: movies})
 })

 })

 app.get('/movies',(req, res)=>{

 let query = req.query.search || 'Spider Man';
 let url = 'http://www.omdbapi.com/?apikey=2edb4869&t=' + query
 request(url, (error, response, body) =>{
    if(!error && response.statusCode == 200){
        let data = JSON.parse(body)
        res.render('results',{data: data })
        }
})
});

app.post('/movies',(req, res) => {

let newMovie = { title: title, poster: poster, genre: genre, plot: plot,

    if(err) console.log(err)
    else res.redirect('/')

    if(err) res.redirect('.')
        else res.render('edit', {
            movie: foundMovie
        })
})

})

app.put('/movies/:id', (req, res) =>{

Movie.findByIdAndUpdate(req.params.id, req.body.movie, (err, updatedMovie) 
  =>{
    if (err) console.log(err)
        else res.redirect('/')
})
})

app.delete('/movies/:id', (req, res) =>{
Movie.findByIdAndRemove(req.params.id, (err) =>{
    if(err) console.log(err)
        else res.redirect('/')
})
})

const port = process.env.PORT || 3000;
app.listen(port, () => console.log(`Listening on port ${port}`));

我从OMDB API中获取数据，当我单击表格下方的按钮时，需要将其保存到数据库中。其他一切正常，我可以使用表单将电影保存到数据库，但是一旦我从API得到响应，就无法弄清楚该怎么做，因此我不必手动键入所有内容。
