JSON请求返回空主体Node.js

Question

I'm using request to get a list of movies from yts.ag/api , and display them in grid of thumbnails, when I click on each of the thumbnail I'm taken to another page which display more details of the movie, when I click the thumbnail first time the data is retrieved, the next time when I click the same movie or other movies the body is empty, I'll have to restart the server for it work and it only works with one request after the request returns an empty body . What seems to be the problem or am I implementing request wrong?

var express = require('express');
var router = express.Router();
var request = require('request');
var url = 'https://yts.ag/api/v2/movie_details.json';

router.get('/:id', function (req, res, next) {
    url += '?movie_id=' + req.params.id;
    request(url, function (error, response, body) {
        if (!error && response.statusCode == 200) {
            if (body) {
                var importJSON = JSON.parse(body);
                res.render('movie', {title: 'Hypertube - Torrent streaming', moviedetails: importJSON.data.movie});
            }else {
                res.render('movie', {title: 'Hypertube - Torrent streaming', moviedetails: false});
            }
        }
    });
});

module.exports = router;

Answer 1

You are adding the query string containing movie_id to the request URL over and over again. So only the first request will work while all subsequent requests have an invalid request URL. Instead create a new request URL in your request callback. In addition, you just ignore any errors that you might get.
