HTTPUrlConnection和.torrent文件

Question

我正在尝试创建独立的file服务器，以编程方式搜索torrent文件(例如.从torrentz.eu下载。

我完全疯了下载单个洪流文件，它似乎服务器响应是不同的使用浏览器或java。

这是一个脚本：

      connection = (HttpURLConnection)url.openConnection();

            connection.setRequestProperty("Cookie", cookies);
                    System.setProperty("http.agent", "");
                    connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");

                    connection.setRequestMethod("GET");
                    connection.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
                    connection.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
                    connection.setRequestProperty("Connection", "keep-alive");
                    connection.setRequestProperty("Content-Language", "en-US");
                    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                    connection.setRequestProperty("Connection", "Keep-Alive");            
                    connection.setConnectTimeout(22000);
                    connection.setReadTimeout(12000);
                    connection.setUseCaches(false);
                    connection.setDoInput(true);
                    connection.setDoOutput(true);

    connection.connect();
    respCode = connection.getResponseCode();

    if(respCode != 200){
    // do something..
    return false;
    }

    ByteArrayOutputStream list = new ByteArrayOutputStream();
stream = connection.getInputStream();

            byte[] buffer = new byte[512];
            int c;
            while ((c = stream.read(buffer)) != -1) {
                if(c > 0){
                    list.write(buffer, 0, c);
                }
            }
            list.flush();
            stream.close();

此代码适用于html、图像文件、ecc。但是不可能获得.torrent文件，它们已经损坏：

例子: UBUNTU，https://torcache.net/torrent/B415C913643E5FF49FE37D304BBB5E6E11AD5101/[katproxy.com]ubuntu.14.10.desktop.64bit.iso.torrent

• 浏览器下载的.torrent文件大小: 44920字节
• java下载的.torrent文件大小: 44795字节135字节丢失！只是为什么？？

发现问题了！

文件被压缩了！可能，默认情况下浏览器会自动解压.非常感谢你！
