Question

我正在尝试使用罗马，只是为了测试，我试图获取一个简单的RSS提要并继续获取＆＃34;无效的XML＆＃34;错误。我实施this solution中给出的解决方案，但它不适用于我。我做错了什么？

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：

以下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'
}

我必须错过一些简单的事情...如果有人能指出我可能有帮助的任何罗马文件。另外，如果你想推荐一些更容易使用的东西，我不会设置在罗马和任何其他java的RSS解析库。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"));

见also this issue about deprecation of rome-fetcher。有一个关于如何使用Apache HttpClient获取提要的示例。
