Próbuję pobrać zawartość HTML strony internetowej i uzyskać status 416. Znalazłem jedno rozwiązanie, które poprawnie poprawia kod statusu jako 200, ale nadal nie pobiera właściwej treści. Jestem bardzo blisko, ale czegoś brakuje. Proszę pomóż.

Kod o statusie 416:

    public static void main(String[] args) {
        String URL="http://www.xyzzzzzzz.com.sg/";

        HttpClient client = new org.apache.commons.httpclient.HttpClient();
        org.apache.commons.httpclient.methods.GetMethod method = new org.apache.commons.httpclient.methods.GetMethod(URL);
        client.getHttpConnectionManager().getParams().setConnectionTimeout(AppConfig.CONNECTION_TIMEOUT);
        client.getHttpConnectionManager().getParams().setSoTimeout(AppConfig.READ_DATA_TIMEOUT);
        String html = null; InputStream ios = null;
        try {
            int statusCode = client.executeMethod(method);

            ios = method.getResponseBodyAsStream();
            html = IOUtils.toString(ios, "utf-8");
            System.out.println(statusCode);
        }catch (Exception e) {
            e.printStackTrace();
        } finally {
            if(ios!=null) {
                try {ios.close();} 
                catch (IOException e) {e.printStackTrace();}
            }
            if(method!=null) method.releaseConnection();
        }

        System.out.println(html);
    }

Code with 200 status (but htmlContent is not proper):

    public static void main(String[] args) {

        String URL="http://www.xyzzzzzzz.com.sg/";

        HttpClient client = new org.apache.commons.httpclient.HttpClient();
        org.apache.commons.httpclient.methods.GetMethod method = new org.apache.commons.httpclient.methods.GetMethod(URL);
        client.getHttpConnectionManager().getParams().setConnectionTimeout(AppConfig.CONNECTION_TIMEOUT);
        client.getHttpConnectionManager().getParams().setSoTimeout(AppConfig.READ_DATA_TIMEOUT);
        String html = null; InputStream ios = null;
        try {
            int statusCode = client.executeMethod(method);
            if(statusCode == HttpStatus.SC_REQUESTED_RANGE_NOT_SATISFIABLE) {
                method.setRequestHeader("User-Agent", "Mozilla/5.0");
                method.setRequestHeader("Accept-Ranges", "bytes=100-1500");
                statusCode = client.executeMethod(method);
            }
            ios = method.getResponseBodyAsStream();
            html = IOUtils.toString(ios, "utf-8");
            System.out.println(statusCode);
        }catch (Exception e) {
            e.printStackTrace();
        } finally {
            if(ios!=null) {
                try {ios.close();} 
                catch (IOException e) {e.printStackTrace();}
            }
            if(method!=null) method.releaseConnection();
        }

        System.out.println(html);
    }
