连接异常- XMLPullParser

Question

我正试着读BBC足球RSS。

下面是我尝试过的代码：：

        URL url = new URL("http://feeds.bbci.co.uk/sport/0/football/rss.xml");        
        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(false);
        XmlPullParser xpp = factory.newPullParser();
        xpp.setInput(url.openConnection().getInputStream(), "UTF_8"); // -- ERROR - Line 21

但我得到了连接异常。

下面的是控制台中的例外：

java.net.ConnectException: Connection timed out: connect

    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
    at com.testing.code.RssParsing.main(RssParsing.java:21)

有什么建议吗？

Answer 1

设置下面的属性会使.

System.setProperty("java.net.useSystemProxies", "true");

Answer 2

我使用以下代码：

URL url = new URL("http://feeds.bbci.co.uk/sport/0/football/rss.xml");
    HttpURLConnection conn = (HttpURLConnection) 
    url.openConnection();
    conn.setReadTimeout(10000);
    conn.setConnectTimeout(15000);
    conn.setRequestMethod("GET");
    conn.setDoInput(true);
    conn.connect();
    InputStream stream = conn.getInputStream();
    xmlFactoryObject = XmlPullParserFactory.newInstance();
    XmlPullParser xpp = xmlFactoryObject.newPullParser();
    xpp.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
    xpp.setInput(stream, null);
    stream.close();
