android - 如何下载 Instagram 页面的 HTML 源代码

Question

在我的应用程序中，我需要下载 Instagram 配置文件的 HTML 源代码并对其进行解析以获取一些信息(媒体和后续计数)。这是我的代码(它适用于我测试过的所有网站，Instagram 除外):

try {
            InputStream in;
            URL url = new URL(urlString);

            URLConnection conn = url.openConnection();
            if(!(conn instanceof HttpURLConnection))
                throw new NoConnectionException("not instanceof http");

            HttpURLConnection httpConn = (HttpURLConnection) conn;
            httpConn.setAllowUserInteraction(false);
            httpConn.setInstanceFollowRedirects(true);
            httpConn.setRequestMethod("GET");

            in = httpConn.getInputStream();

            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            String line;
            String source = "";
            while((line = br.readLine()) != null)
                source += line;
            br.close();
} catch(Exception e) {}

当我用 LogCat 调试它时，String source 是空的。
