使用URLConnection获取页面返回的xml数据

    public static void main(String[] args) throws Exception {

        String path="http://flash.weather.com.cn/wmaps/xml/hubei.xml";
        URL url = new URL(path);//获得url对象
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();  //创建URLConnection连接
        conn.setReadTimeout(5*1000);
        conn.setRequestMethod("GET");
        BufferedReader bufr=new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));//设置文件输入流的编码，和url的编码一致
        String lines="";
        String result="";
        while ((lines=bufr.readLine())!=null) {
            result+=lines;
        }
        System.out.println(result);
    }

特殊的当请求页面被gzip压缩过之后

    public static void main(String[] args) throws Exception {

        String path="http://wthrcdn.etouch.cn/WeatherApi?citykey=101010100";
        URL url = new URL(path);
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
        conn.setReadTimeout(5*1000);
        conn.setRequestMethod("GET");
        BufferedReader bufr=new BufferedReader(new InputStreamReader(new GZIPInputStream(conn.getInputStream()),"UTF-8"));//使用GZIPInputStream解压缩
        String lines="";
        String result="";
        while ((lines=bufr.readLine())!=null) {
            result+=lines;
        }
        System.out.println(result);
    }
