如何使用 Content-Encoding 读取压缩的 HTML 页面：gzip

我请求一个发送内容编码：gzip标题，但卡住了如何阅读它..

My code:

    try {
        URLConnection connection = new URL("http://jquery.org").openConnection();                        
        String html = "";
        BufferedReader in = null;
        connection.setReadTimeout(10000);
    in = new BufferedReader(new InputStreamReader(connection.getInputStream()));            
    String inputLine;
    while ((inputLine = in.readLine()) != null){
    html+=inputLine+"\n";
        }
    in.close();
        System.out.println(html);
        System.exit(0);
    } catch (IOException ex) {
        Logger.getLogger(Crawler.class.getName()).log(Level.SEVERE, null, ex);
    }

输出看起来非常混乱..（我无法将其粘贴到这里，一种符号..）

我相信这是一个压缩内容，如何解析它？

Note:
如果我将 jquery.org 更改为 jquery.com （不发送该标头，我的代码运行良好）

实际上，这是 pb2q 的答案，但我为未来的读者发布了完整的代码

try {
    URLConnection connection = new URL("http://jquery.org").openConnection();                        
    String html = "";
    BufferedReader in = null;
    connection.setReadTimeout(10000);
    //The changed part
    if (connection.getHeaderField("Content-Encoding")!=null && connection.getHeaderField("Content-Encoding").equals("gzip")){
        in = new BufferedReader(new InputStreamReader(new GZIPInputStream(connection.getInputStream())));            
    } else {
        in = new BufferedReader(new InputStreamReader(connection.getInputStream()));            
    }     
    //End        
    String inputLine;
    while ((inputLine = in.readLine()) != null){
    html+=inputLine+"\n";
    }
in.close();
    System.out.println(html);
    System.exit(0);
} catch (IOException ex) {
    Logger.getLogger(Crawler.class.getName()).log(Level.SEVERE, null, ex);
}
