java用get请求xml乱码问题

Question

网址

我在java里面用get请求上面这个网址，获取网页内容的时候，显示出来的是乱码，然而用浏览器显示正常啊，而且上面这个网址的编码格式应该是utf8的，或者是windows-1252的，然而这两种编码我都试过，都是乱码，就是那种一堆问号。怎么搞？
附上我的代码：

    URL url = new URL("http://wthrcdn.etouch.cn/WeatherApi?citykey=101010100");

    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));
    String line;
    while ((line = reader.readLine()) != null){
    System.out.println(line);
    }
    reader.close();

Answer 1

URL url = new URL("http://wthrcdn.etouch.cn/WeatherApi?citykey=101010100");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
InputStream urlStream = new GZIPInputStream(connection.getInputStream());

BufferedReader reader = new BufferedReader(new InputStreamReader(urlStream,"UTF-8"));

String line = "";

while((line = reader.readLine()) != null) {

System.out.println(line);

}

reader.close();

这样写就不会乱码了，如果解决了请采纳！！！
