Question

你好，我有一个问题，我想通过网址使用rss，我不能这样做。例如：

System.setProperty("https.proxyHost", "proxy.example.local");
System.setProperty("https.proxyPort", "80");

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();

URL url = new URL("http://pplware.sapo.pt/feed/");  
InputStream stream = connection.getInputStream();
InputStream stream = url.openStream();  
Document doc = docBuilder.parse(stream);    
System.out.println ("Root element of the doc is " + doc.getDocumentElement().getNodeName());

错误：

java.net.ConnectException: Connection timed out: connect

我需要在IBM网站和论坛中进行此搜索的帮助，并且不解决问题。欢迎 JoãoSousa

如果您可以通过浏览器打开http://pplware.sapo.pt/feed/，则不需要前两行：

System.setProperty("https.proxyHost", "proxy.example.local");
System.setProperty("https.proxyPort", "80");

没有proxy.example.local。

当然，删除行

InputStream stream = connection.getInputStream();

最终的代码是

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();

    URL url = new URL("http://pplware.sapo.pt/feed/");
    InputStream stream = url.openStream();
    Document doc = docBuilder.parse(stream);
    System.out.println("Root element of the doc is "
            + doc.getDocumentElement().getNodeName());

它对我有用。

按URL读取rss - java.net.ConnectException：连接超时：connect
