复制小程序

    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);

    }
