如何使用Content-Encoding读取压缩的HTML页面：gzip [英] How to read compressed HTML page with Content-Encoding : gzip

问题描述

我请求一个发送 Content-Encoding：gzip 标头的网页，但却被卡住了怎么读... ..

I request a web page that sends a Content-Encoding: gzip header, but got stuck how to read it..

My代码：

    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);
    }

输出看起来很乱......（我无法将其粘贴到此处，一种符号..）

The output looks very messy.. (I was unable to paste it here, a sort of symbols..)

我相信这是一个压缩内容，如何解析它？

I believe this is a compressed content, how to parse it?

注意：

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

Note:
If I change jquery.org to jquery.com (which don't send that header, my code works well)

推荐答案

有一个类：GZIPInputStream 。它是一个 InputStream ，因此使用起来非常透明。

There is a class for this: GZIPInputStream. It is an InputStream and so is very transparent to use.
