通過URL讀取rss - java.net.ConnectException：連接超時：connect

Question

你好，我有一個問題，我想通過網站，我不能做的rss消費RSS。 例子：

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()); 

錯誤：

java.net.ConnectException: Connection timed out: connect 

我需要幫助IBM的網站和論壇，本次搜索，並且不解決問題。 問候 喬奧·索薩

Answer 1

如果可以打開http://pplware.sapo.pt/feed/槽瀏覽器，你不需要是前兩行：

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

有沒有proxy.example.local。

，當然，刪除行

InputStream stream = connection.getInputStream(); 

最終代碼會

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()); 

它爲我工作。
