javascript - 在 Angular 应用程序上将 XML RSS feed 转换为 Json

Question

我有一个像这样的 API https://blog.com/rss。它返回以下 xml 作为博客提要。

注意:我已经看到了这个。但这是针对nodejs应用程序的。 https://github.com/nasa8x/rss-to-json

那么你能告诉我如何检索图像、标题、日期和描述吗它？即 Json 输出。

之后我需要在 html 页面上显示它，如下所示:

注意:这只是一个节点。根据 feed 输出，它将有许多节点。即ngFor循环

.html

  <div class="card">
          <div class="card-wrapper">
            <img class="card-img-top" src="../../../assets/img/blog-1.png" alt="Card image cap">
            <div class="card-body">
              <h5 class="card-title"> 5 People Management Skills Every Manager Needs</h5>
              <span class="card-date">12.12.2018</span>
              <p class="card-text">Want to see domain names for sale in your own language? Browse domain names by
                languages.</p>
            </div>
          </div>

https://blog.com/rss 输出:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<rss xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" version="2.0">

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p> <p></p>

希望您会发现这个库有帮助:

rss-parser: https://github.com/bobby-brennan/rss-parser

- 该库支持 NodeJS 和 web

这是在浏览器中使用回调的示例:

<script src="/node_modules/rss-parser/dist/rss-parser.min.js"></script>
<script>

// Note: some RSS feeds can't be loaded in the browser due to CORS security.
// To get around this, you can use a proxy.
const CORS_PROXY = "https://cors-anywhere.herokuapp.com/"

let parser = new RSSParser();
parser.parseURL(CORS_PROXY + 'https://www.reddit.com/.rss', function(err, feed) {
  console.log(feed.title);
  feed.items.forEach(function(entry) {
    console.log(entry.title + ':' + entry.link);
  })
})

</script>
