返回信息流URL url = new URL(urlString);
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
XMLReader reader = parser.getXMLReader();
handler = new RSSHandler();
reader.setContentHandler(handler);
InputStreamReader in = new InputStreamReader(url.openStream(), "GBK");
InputSource inputsouce = new InputSource(in);
reader.parse(inputsouce);
用这种方法获取 rss文件的流，并且解析，之前好的，今天运行突然报错，错误信息如下：
