我正在尝试使用 Rome 并且只是为了测试,我正在尝试获取一个简单的 RSS 提要并不断收到“无效 XML”错误。我实施了此解决方案中给出的解决方案,但它对我不起作用。我究竟做错了什么?

代码:

  private void fetchRSSDetails()  {
    HttpClientFeedFetcher feedFetcher = new HttpClientFeedFetcher();
    try {
      SyndFeed feed = feedFetcher.retrieveFeed(new URL("http://feeds.bbci.co.uk/news/world/rss.xml"));
      System.out.println(feed.getLink());
    } catch (IllegalArgumentException | IOException | FeedException | FetcherException e) {
      e.printStackTrace();
    }
}

我得到的例外是:

下面是我如何将罗马添加到我的 Android 项目中。

compile ('com.rometools:rome:1.5.1'){
    exclude module: 'slf4j-api'
}
compile ('com.rometools:rome-fetcher:1.5.1'){
    exclude module: 'slf4j-api'
}

我一定错过了一些简单的东西......如果有人能指出我对罗马的任何好的文档可能会有所帮助。此外,如果你想推荐一些更容易使用的东西,我没有设置罗马和任何其他 RSS 解析库可以做的事情。我只需要解析 RSS 提要。

我无法复制您的问题,但您可以尝试为 feed fetcher 添加您自己的用户代理字符串(以防他们重定向某些用户代理):

SyndFeed feed = feedFetcher.retrieveFeed("your-rss-reader-user-agent", new URL( "http://feeds.bbci.co.uk/news/world/rss.xml"));

另请参阅有关弃用 rome-fetcher 的问题。有一个关于如何使用 Apache HttpClient 获取提要的示例。
