我如何获取多个 RSS 提要并将它们合并为一个提要,然后将合并的提要转换为 JSON 数据? (JavaScript)

How can i fetch multiple RSS feeds and merge them in one feed, then convert the merged feed to JSON data? (JavaScript)

我正在尝试将多个 RSS 提要合并为一个并将其转换为 JSON。为了合并 RSS 提要,我使用了这个包:rss-combiner

这是我用来合并 RSS 提要的代码:

var RSSCombiner = require('rss-combiner');

var feedConfig = {
  title: 'Tech news from Guardian and BBC',
  size: 20,
  feeds: [
    'http://feeds.bbci.co.uk/news/technology/rss.xml',
    'https://www.theguardian.com/uk/technology/rss'
  ],
  pubDate: new Date()
};

RSSCombiner(feedConfig)
.then(function (combinedFeed) {
  xml = combinedFeed.xml();
  console.log(xml);
});

然后将提要转换为 JSON 我使用了这个包:rss-to-json 和这段代码,它有效:

var Feed = require('rss-to-json');

Feed.load('https://codek.tv/feed/', function(err, rss){
   console.log(rss);
});

问题是当我尝试将合并的 Feed 转换为 JSON 时,使用此代码我没有得到任何结果:

var RSSCombiner = require('rss-combiner');
var Feed = require('rss-to-json');

var feedConfig = {
  title: 'Tech news from Guardian and BBC',
  size: 20,
  feeds: [
    'http://feeds.bbci.co.uk/news/technology/rss.xml',
    'https://www.theguardian.com/uk/technology/rss'
  ],
  pubDate: new Date()
};

// combine feeds
RSSCombiner(feedConfig)
.then(function (combinedFeed) {
  var xml = combinedFeed.xml();

  // convert combined feed to json
  Feed.load(xml, function(err, rss){ 
    console.log(rss);
  });
});

我认为 rss-to-json 要求 URL;您传递的是 XML 结果。为什么不在合并 RSS 后直接使用 xml2js

const RSSCombiner = require('rss-combiner');
const xml2js = require('xml2js');

const feedConfig = {
  title: 'Tech news from Guardian and BBC',
  size: 20,
  feeds: [
    'http://feeds.bbci.co.uk/news/technology/rss.xml',
    'https://www.theguardian.com/uk/technology/rss',
  ],
  pubDate: new Date(),
};

RSSCombiner(feedConfig)
  .then((combinedFeed) => {
    const xml = combinedFeed.xml();
    const parser = xml2js.Parser();

    parser.parseString(xml, (err, result) => {
      console.log(result);
    });
  });
