Google 新闻 RSS 提要 Android 开发

Question

我试图在我的 andorid 应用程序中从 google 新闻 rss feed 获取新闻，但我无法获得正确的响应。当我尝试使用邮递员进行相同操作时，我得到了回复。

代码：

    URL url;
    HttpURLConnection connection = null;

    try {

        //Create connection
        url = new URL(targetURL);
        connection = (HttpURLConnection)url.openConnection();
        connection.setRequestProperty("content-type", "application/xml; charset=utf-8");

        InputStream is;

        int status = connection.getResponseCode();

        if (status != HttpURLConnection.HTTP_OK) {

            is = connection.getErrorStream();

        }
        else {

            is = connection.getInputStream();

        }


        BufferedReader rd = new BufferedReader(new InputStreamReader(is));
        String line;
        StringBuffer response = new StringBuffer();

        while((line = rd.readLine()) != null) {

            response.append(line);

            response.append('\r');
        }

        rd.close();

        return response.toString();

    } catch (Exception e) {


        return null;

    } finally {

        if(connection != null) {
            connection.disconnect();
        }
    }

回复：

Postman 中的响应：Postman Response

需要更改什么才能获得 link 的响应？任何帮助将不胜感激。

使用RSS Parser Library可以轻松实现。只需在你的 gradle 中添加依赖项，然后你就可以做这样的事情

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String urlString = "https://news.google.com/news/rss/story/dUuojVTpzSeUCKMyoBbnmsAFajvtM?ned=in&hl=en-IN&gl=IN";
    Parser parser = new Parser();
    parser.execute(urlString);
    parser.onFinish(new Parser.OnTaskCompleted() {
        @Override
        public void onTaskCompleted(ArrayList<Article> list) {
            //what to do when the parsing is done
            //the Array List contains all article's data. For example you can use it for your adapter.
            Toast.makeText(MainActivity.this,"completed", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError() {
            Toast.makeText(MainActivity.this,"error", Toast.LENGTH_SHORT).show();
        }
    });

}
